Some individuals healingg one or more factors that contribute to impaired wound healing, which can lead to chronic ulcerations or nonhealing wounds, woknd can complicate the surgical healiny. The risk factors associated with impaired wound healing due to patient factors, underlying disease, and disease treatments are reviewed here.

Pulmonary complications Metabolic support for optimal health recommendations on smoking cessation and nicotine replacement therapy are discussed Impairer detail elsewhere. See "Strategies to reduce postoperative pulmonary complications healjng adults", section on Impaired wound healing cessation' and "Overview of smoking cessation management in adults".

The constituents eound tobacco smoke and mechanisms responsible for the Impairef and other effects of smoking have not been fully elucidated; for many years nicotine was Nutrition for athletic performance to be responsible, but uealing constituents Ipaired tobacco smoke may Impairec a greater impact.

Tobacco Weight Management Supplement is a complex mixture of compounds eg, nicotine, carbon woind, tar, hezling cyanide, nitrogen oxides, N-nitrosamines, Impairde, benzeneseveral of which have a physiologic impact [ ].

The detrimental effect of smoking on wound healing is multifactorial, with mechanisms that include vasoconstriction causing a relative ischemia of operated tissues, a reduced inflammatory response, impaired bacteriocidal mechanisms, and alterations of collagen metabolism [ 18 ].

These are postulated to impair wound healing and cause wound dehiscence and incisional hernia. See "Basic principles of wound healing", section on 'Wound healing'. Smoking is associated with postoperative wound healing complications, which occur more often in smokers compared with nonsmokers as well as in former smokers compared with those who never smoked.

A systematic review identified four randomized trials that evaluated the impact of preoperative smoking cessation four- to eight-week intervals of abstinence on postoperative wound healing.

Preoperative smoking cessation significantly reduced the incidence of surgical site infection odds ratio [OR] 0. In a separate study, current or past smoking was associated with an increased risk for postoperative infection OR 1.

Although smoking-induced vasoconstriction, mediated by nicotinecan reduce blood flow by up to 40 percent, the effect appears to be temporary, with tissue blood flow and oxygen levels restored to normal levels within 45 minutes [ ].

Most tissues with an adequate blood supply probably tolerate these transient alterations; however, tissue flaps, which have a fragile blood supply, and other ischemic tissues eg, moderate-to-severe peripheral artery disease might be vulnerable to smoking-induced reductions in blood flow.

With respect to other effects of nicotine, both impaired and stimulated wound healing have been identified in experimental studies; however, no clinically significant detrimental or beneficial effects on wound healing have been demonstrated with the use of nicotine replacement therapies [ ].

AGING — Skin is not excluded from the complex processes of aging. The supply of cutaneous nerves and blood vessels decreases with age, in addition to a general thinning of tissue, including the dermis and basement membrane.

There is a progressive loss of collagen and diminished ability to produce more collagen. These physiologic changes associated with aging contribute to slowed or impaired wound healing in older adults [ 35,36 ].

In several studies, the extremes of age infants and older individuals were identified as a risk factor for surgical site infection SSI [ 37 ]. One cohort study of more thanadult surgical patients found that increasing age independently predicted an increased risk of SSI only until age 65 years risk increasing 1.

See 'Infection' above and "Overview of perioperative nutrition support", section on 'Consequences of malnutrition in surgical patients' and "Overview of the evaluation and management of surgical site infection".

Thus, we generally prefer to screen for malnourishment by obtaining preoperative serum prealbumin and albumin levels in potentially high-risk patients and monitoring them to optimize nutritional status. Prealbumin and albumin are not perfect markers of nutritional status; however, these should be obtained on patients with nonhealing wounds [ 43 ].

In addition, measures of frailty and functional status may be linearly related to malnutrition and might also be incorporated into an assessment [ 44,45 ]. These are typically pressure wounds, similar in pathogenesis and appearance to neuropathic wounds occurring in areas of bony prominence such as the sacrum, knees, ankle malleoli, and heels.

The sacrum may be particularly at risk when the presence of incontinence in spinal cord patients leads to a moist environment [ 46 ]. See "Epidemiology, pathogenesis, and risk assessment of pressure-induced skin and soft tissue injury". Immobilization in the absence of pressure is probably not a risk factor for wound development or chronicity.

In fact, complete immobilization with total contact casting is an effective treatment for plantar diabetic foot ulceration [ 47 ].

The inflammatory phase of wound healing may be blunted in patients on long-term immune suppression such as is used in treating transplant patients and HIV patients, among others. Chemotherapy — The administration of chemotherapy may have a detrimental effect on wound healing, specifically through its direct or indirect effects on vascular endothelial growth factor VEGF.

VEGF is an important factor contributing to angiogenesis during the early stages of wound healing but may also be an important regulator in malignancy and thus is a target of cancer therapy [ 52 ].

See "Toxicity of molecularly targeted antiangiogenic agents: Non-cardiovascular effects", section on 'Delayed wound healing' and "Toxicity of molecularly targeted antiangiogenic agents: Non-cardiovascular effects", section on 'Cutaneous toxicity'. Furthermore, neuropathy secondary to chemotherapy can produce loss of protective sensation and instability in a similar manner to diabetes.

Glucocorticoids — Glucocorticoids may not have the same degree of negative effect as other immunosuppressive therapies, and locally applied topical steroids are often used in the treatment of chronic wounds [ 53 ]. While some degree of anti-inflammation may prevent wounds from becoming arrested in the inflammatory stage, significant suppression of inflammation can prevent wounds from progressing into the next stages of wound healing.

This is a subjective and currently unquantifiable inflammatory balance [ 54,55 ]. Several studies have demonstrated the potential beneficial effects of topical steroid application in the treatment of chronic wounds, particularly when an abnormal and uncontrolled inflammatory stage is suspected within the stages of wound healing.

Radiation — Radiation therapy has evolved as a powerful tool for tumor control as a sole therapy or administered adjunctively. More than 50 percent of cancer patients receive some form of radiation treatment, and, despite improvements in radiation technique, radiation-induced injury still contributes to poor wound healing.

The term "radiation injury" refers to the morphologic and functional changes that can occur in noncancerous tissue as a direct result of ionizing radiation and may include apoptosis cell death with low doses of radiation or outright tissue necrosis with higher doses of radiation. Irradiated skin in the chronic stage is thin, hypovascular, extremely painful, and easily injured by slight trauma or infection [ 56 ].

See "Clinical manifestations, evaluation, and diagnosis of acute radiation exposure", section on 'Cutaneous'. Skin ulcers due to radiation injury are more commonly delayed in presentation and are due to ischemic tissue changes.

Characteristic features of delayed radiation injury include telangiectasia and eccentric myointimal proliferation in the small arteries and arterioles.

The proliferative changes may progress to obstruction, or the lumen may thrombose. These ulcers heal very slowly and may persist for several years. Given the changes that are known to occur with respect to the perfusion of irradiated tissue and the phases of wound healing, surgical incisions in these locations are more likely to develop a wound complication.

If an incision is planned in an area of radiation exposure, the optimal timing for surgery remains unclear. While some have recommended waiting three to six weeks after radiation therapy to perform an incision or conversely to delay radiation therapy three to four weeks after an incision, surgery in the immediate perioperative period has been reported [ 57,58 ].

It is likely that the dosing and duration of radiation therapy affects this decision making, preventing the ability to make generalized recommendations; each case needs to be individualized. DIABETES — Numerous cytologic factors contribute to impaired wound healing in patients with diabetes [ 59 ].

These include decreased or impaired growth factor production, angiogenic response, macrophage function, collagen accumulation, epidermal barrier function, quantity of granulation tissue, keratinocyte and fibroblast migration and proliferation, number of epidermal nerves, bone healing, and abnormal balance between the accumulation of extracellular matrix components and their remodeling by matrix metalloproteinases.

Diabetes is a particularly important risk factor for the development of chronic wounds from neuropathy and vasculopathy, which increase the risk of infection and delay healing [ 8,60 ]. Diabetes is frequently associated with peripheral artery disease PAD with atherosclerosis developing at a younger age and affecting more distal arteries below the knee eg, popliteal, tibial arteries.

PAD in combination with diabetic neuropathy contributes to higher rates of nonhealing wounds and limb loss in diabetic patients compared with those without diabetes [ 61,62 ]. Up to one-third of people with diabetes in the United States will develop a foot ulcer [ 60,63,64 ].

Peripheral artery obstruction is present in approximately 20 percent of these patients and diabetic neuropathy in up to 50 percent of these patients [ 56,60 ].

Neuropathy alone can be responsible for the development of diabetic foot ulcers. Neuropathy associated with diabetes affects sensory, motor, and autonomic nerves. Sensory neuropathy diminishes the perception of pain that is protective when tissue injury has occurred [ 65 ].

Patients with diabetes may not be aware of the injury, particularly if the injured region cannot be seen or if the patient has a visual impairment. The motor nerves to the intrinsic muscles of the foot are affected in approximately 50 percent of patients with diabetes, resulting in claw deformities in the digits that transfer pressure to the plantar metatarsal heads.

Increased local tissue pressure on the plantar surface or in other regions where bony deformities contact the shoe may lead to skin erosion and ulceration that may go unnoticed in patients with sensory deficits. In addition, autonomic neuropathy causes the skin to become dry and susceptible to skin fissures, tearing, and infection due to a loss of sweat and oil gland function.

Loss of vascular tone may lead to foot edema [ 66 ]. Peripheral artery disease — Peripheral artery disease PAD with multilevel arterial obstruction decreases arterial blood flow, diminishes the delivery of oxygen and nutrients to the tissues, and impairs removal of metabolic waste products.

Introduction In a way, history of wound care is the history of humankind. Function Normal Wound Healing At times difficult to appreciate, the wound healing process WHP is a highly structured and well-organized biological process [6] [7] [6].

Wound healing can be divided into 4 phases [8] : Hemostasis. Issues of Concern Factors Affecting Wound Healing The WHP is very complex and involves high levels of coordination between multiple tissues and cell types [6]. Diabetes There is no doubt that diabetes plays a detrimental role in wound healing.

Tobacco Abuse Cigarette smoking leads to numerous adverse health consequences, including various types of cancer, primary lung disease, and cardiovascular disease, among others [12] [13]. Malnutrition The nutritional needs of the healing wound are very complex.

Obesity Obesity is a significant factor in surgical wound healing. Stress Stress has been demonstrated to be a major contributor to a broad range of health conditions and illnesses, including cardiovascular disease, cancer, and obesity.

Clinical Significance Wound healing is a vast topic area, with many aspects remaining poorly understood despite the tremendous amount of progress over the past few decades. Other Issues Methods and Techniques Known to Improve Wound Healing Negative Pressure Therapy Numerous wound management devices have been introduced over the years to improve wound healing.

Maggot Debridement While considered by many as archaic, maggot debridement therapy MDT has been shown unequivocally to be of benefit in wound healing [46] [47].

Hyperbaric Oxygen Hyperbaric oxygen therapy HBOT is another treatment modality that has been around for quite some time, but only recently saw a resurgence in interest due to promising effects on the WHP, especially in the setting of chronic and complicated wounds [54] [55]. Enhancing Healthcare Team Outcomes The best management of wounds is taken care of by an interprofessional team of a nurse specializing in wound care and a clinician with significant wound experience.

Abstract Type 1 diabetes is associated with systemic low grade inflammation LGI. Introduction Type 1 diabetes T1D is a metabolic disorder characterized by chronic hyperglycemia and alterations in carbohydrate, lipid and protein metabolism. Figure 1. Full size image. Figure 2.

Figure 3. Figure 4. Figure 5. Figure 6. Figure 7. Figure 8. Discussion Diabetes is a metabolic disorder characterized by chronic LGI. Peritoneal macrophages profile Peritoneal exudates cells were obtained by lavage of the peritoneal cavity with cold PBS. Nitrite and arginine measurements Macrophages were isolated by adherence for arginase activity measurements.

Analysis of macrophages stimulated with IL-4 An assay of dose versus response was performed in vivo in resident peritoneal macrophages from healthy WT mice. Table 1 Sequence of primers. Full size table. Additional factors involved in this complex process include blunting of the immune and inflammatory responses.

Interestingly, these ill-effects of obesity are largely reversible through weight loss [24]. Stress has been demonstrated to be a major contributor to a broad range of health conditions and illnesses, including cardiovascular disease, cancer, and obesity.

Stress states lead to upregulation of stress hormones via the hypothalamic-pituitary axis and the release of adrenocortical hormones. Resultant changes include elevated levels of cortisol, glucocorticoids, and catecholamines. Cortisol works to blunt the immune response by blocking the production of important cytokines such as IL-1beta, IL-6, and TNF-alpha.

The impairment of immune response ultimately leads to deficient wound healing [25] [26]. Wound healing is a vast topic area, with many aspects remaining poorly understood despite the tremendous amount of progress over the past few decades.

Various co-morbid conditions e. More recently, a better understanding of the role micronutrients play in wound healing, along with the introduction of novel wound care therapeutics e.

Numerous wound management devices have been introduced over the years to improve wound healing. However, none have been as influential and successful as negative pressure wound therapy NPWT therapy. NPWT involves the application of subatmospheric pressure on wound via a sponge-based system with an airtight seal directly over the wound, connected under sealed conditions to a suction device.

Benefits of NPWT are realized via several different mechanisms. First, the subatmospheric pressure applied to the wound helps to remove wound exudate and other materials that are known to impair the WHP.

Secondly, the presence of subatmospheric pressure promotes angiogenesis and tissue perfusion by increasing cellular proliferation and migration into the wound. The suction also assists in bringing wound edges together. When combined, all of the above elements and mechanisms work synergistically to help speed up wound healing.

NPWT devices can be used on a wide variety of wounds, such as pressure ulcers, large abdominal wounds, traumatic wounds, as well as complex, difficult-to-cover tissue defects following debridement operations e.

Of note, NPWT is contraindicated in certain situations, such as wound surfaces involving malignancy, untreated osteomyelitis, non-enteric and unexplored fistulae, and necrotic tissue with eschar e. It has long been known that Vitamin A may have beneficial effects on wound healing in the setting of previous systemic exposure to corticosteroids.

More specifically, Vitamin A has been shown to overcome the inhibitory effects of cortisone and related corticosteroids on the rate of gain in tensile strength of the wound [34] [35] [34]. This may be especially pronounced in early stages of the WHP.

At the same time, Vitamin A by itself does not seem to be a significant modulator of the WHP, suggesting that its beneficial action in the setting of prior corticosteroid use is related to the interaction s specific to corticosteroid-specific pathway s [36] [37] [36]. Vitamin C and zinc have both been found to improve wound healing characteristics, although clinical adoption and implementation of this therapeutic combination is less than universal.

Mechanistically, vitamin C has several favorable effects on the WHP. First, it is a powerful antioxidant and free radical scavenger. Second, it is important to systemic immunity, and along with Zinc helps boost the immune system when taken in the postoperative period. Together with Arginine and Zinc, Vitamin C is important for collagen synthesis.

The evidence is strongest for supplementing vitamin C and zinc during the immediate postoperative period [38] [39] [40] [38].

Among other interesting and important developments in wound care, there is evidence that vitamin-D supplementation may help positively modulate impaired wound healing, although further research toward mechanistic understanding is required in this area.

More specifically, the role of vitamin D in the WHP may be indirect, through beneficial effects on closely related physiological processes, such as glucose homeostasis [41] [42].

Finally, another vast topic area that is worth mentioning but too extensive to fully discuss in this review is the use of growth factors in the modulation of the WHP.

It has been demonstrated that delivery of various specific growth factors e. Further research is required to better define mechanisms of action, potential side effects, and the overall risk-benefit of human application of such therapies.

While considered by many as archaic, maggot debridement therapy MDT has been shown unequivocally to be of benefit in wound healing [46] [47]. MDT is based on the observation that fly larvae only debride dead, devitalized, and necrotic tissue.

Healthy, viable tissue is not threatened during the MDT, making this therapy uniquely suited for debridement of devitalized tissues with truly surgical precision [48]. In fact, MDT is considered a form of "biosurgery. This liquefied material is then ingested, resulting in effective debridement of the tissue of interest.

It has been shown that MDT can help debride large wounds in as little as 72 hours, resulting in a viable granulation bed that is suitable for conventional wound management. In addition to chemical debridement, larval secretions are also characterized by significant antimicrobial activity, active against a wide range of pathogenic and often antibiotic-resistant bacteria, mostly gram-positive species.

Maggots work best on moist environments with sufficient oxygen supply [49]. They are approved for use in non-healing necrotic skin and soft tissue wounds, pressure and venous stasis ulcers, neuropathic foot ulcers, and non-healing traumatic or surgical wounds [50].

Most recent developments in this area include the introduction of transgenic maggots that secrete human growth factors in their saliva [51].

Clinical applications of this therapy are continually expanding. Of interest, application of MDT can be accomplished through direct exposure of the maggots to the wound bed using a specialized "housing" or through indirect exposure using larvae contained within a sealed, semi-permeable bag [52] [53].

Hyperbaric oxygen therapy HBOT is another treatment modality that has been around for quite some time, but only recently saw a resurgence in interest due to promising effects on the WHP, especially in the setting of chronic and complicated wounds [54] [55]. Chronic wounds, often seen as a consequence of diabetes, arterial or venous disease, are increasingly common and result in significant impact on the affected patients, their caretakers, and the healthcare system in general.

The beneficial action of HBOT on wound healing is predicated on the increased supply of oxygen to wounds that are refractory to other, more conventional treatment approaches [56]. In practice, HBOT involves the patient being temporarily enclosed in a special chamber that in many ways approximates conditions used for deep sea divers and involves gradual "dive" followed by a pre-defined time interval at a certain "oxygen pressure level," and subsequent gradual "resurfacing" process.

While in the chamber, the patient is exposed to markedly elevated concentrations of pure oxygen, leading to elevation of systemic and tissue oxygen levels. It has been demonstrated that HBOT is effective in improving the course of chronic diabetes-related extremity wounds, potentially reducing the need for major but not necessarily minor amputations.

Available evidence suggests beneficial effects of HBOT on wounds are usually apparent within approximately 6 weeks of therapy, but long-term beneficial effects continue to be questionable. Another area where HBOT can be beneficial is the management of necrotizing soft tissue infections e.

Additional difficult-to-treat types of wounds that have been speculated to benefit from HBOT are the chronic pressure ulcers due to its inherently "ischemic" nature and venous ulcers; however, there is no solid evidence to support HBOT for either of these indications at this time [57] [60].

The best management of wounds is taken care of by an interprofessional team of a nurse specializing in wound care and a clinician with significant wound experience.

Caring for wounds not only involves regular follow-ups but patient education. A coordinated team approach has been shown to be most effective in wound management. Disclosure: Brian Wernick declares no relevant financial relationships with ineligible companies.

Introduction In a way, history of wound care is the history of humankind. Function Normal Wound Healing At times difficult to appreciate, the wound healing process WHP is a highly structured and well-organized biological process [6] [7] [6].

Wound healing can be divided into 4 phases [8] : Hemostasis. Issues of Concern Factors Affecting Wound Healing The WHP is very complex and involves high levels of coordination between multiple tissues and cell types [6].

Diabetes There is no doubt that diabetes plays a detrimental role in wound healing. Tobacco Abuse Cigarette smoking leads to numerous adverse health consequences, including various types of cancer, primary lung disease, and cardiovascular disease, among others [12] [13].

Malnutrition The nutritional needs of the healing wound are very complex. Obesity Obesity is a significant factor in surgical wound healing.

Stress Stress has been demonstrated to be a major contributor to a broad range of health conditions and illnesses, including cardiovascular disease, cancer, and obesity. Clinical Significance Wound healing is a vast topic area, with many aspects remaining poorly understood despite the tremendous amount of progress over the past few decades.

Other Issues Methods and Techniques Known to Improve Wound Healing Negative Pressure Therapy Numerous wound management devices have been introduced over the years to improve wound healing.

Amino Acids. This might also result in a pathologic cycle as the presence of necrotic tissue additionally serves as a nidus for bacterial proliferation. Surgical site infection — Surgical site infection SSI is defined by the United States Centers for Disease Control and Prevention as infection related to an operative procedure that occurs at or near the surgical incision within 30 days of the procedure or within 90 days if prosthetic material is implanted at surgery table 1 [ 12 ].

SSIs are often superficial and localized to the incision site but can also extend into deeper adjacent structures. See "Overview of the evaluation and management of surgical site infection" and "Complications of abdominal surgical incisions", section on 'Surgical site infection'.

The degree of contamination of a surgical wound at the time of the operation is an important risk factor for infection. See "Overview of the evaluation and management of surgical site infection", section on 'Surgical wound classification'. Cellulitis — Cellulitis is both a descriptive term used to describe a clinical finding and a pathophysiologic process accompanying infection.

Cellulitis refers to a non-necrotizing inflammation of the skin and subcutaneous tissue. Infectious changes causing cellulitis typically involve direct inoculation through the skin.

However, the source is frequently not obvious and may involve microscopic breaches in the integument. See "Acute cellulitis and erysipelas in adults: Treatment". Burn wound infection — Thermal injury with tissue loss is often accompanied by concomitant immunosuppression, which can place the injured person at greater risk for infection [ 16 ].

See "Burn wound infection and sepsis". Pulmonary complications and recommendations on smoking cessation and nicotine replacement therapy are discussed in detail elsewhere. See "Strategies to reduce postoperative pulmonary complications in adults", section on 'Smoking cessation' and "Overview of smoking cessation management in adults".

The constituents of tobacco smoke and mechanisms responsible for the vasoactive and other effects of smoking have not been fully elucidated; for many years nicotine was presumed to be responsible, but other constituents of tobacco smoke may have a greater impact. Tobacco smoke is a complex mixture of compounds eg, nicotine, carbon monoxide, tar, hydrogen cyanide, nitrogen oxides, N-nitrosamines, formaldehyde, benzene , several of which have a physiologic impact [ ].

The detrimental effect of smoking on wound healing is multifactorial, with mechanisms that include vasoconstriction causing a relative ischemia of operated tissues, a reduced inflammatory response, impaired bacteriocidal mechanisms, and alterations of collagen metabolism [ 18 ].

These are postulated to impair wound healing and cause wound dehiscence and incisional hernia. See "Basic principles of wound healing", section on 'Wound healing'. Smoking is associated with postoperative wound healing complications, which occur more often in smokers compared with nonsmokers as well as in former smokers compared with those who never smoked.

A systematic review identified four randomized trials that evaluated the impact of preoperative smoking cessation four- to eight-week intervals of abstinence on postoperative wound healing. Preoperative smoking cessation significantly reduced the incidence of surgical site infection odds ratio [OR] 0.

In a separate study, current or past smoking was associated with an increased risk for postoperative infection OR 1. Although smoking-induced vasoconstriction, mediated by nicotine , can reduce blood flow by up to 40 percent, the effect appears to be temporary, with tissue blood flow and oxygen levels restored to normal levels within 45 minutes [ ].

Most tissues with an adequate blood supply probably tolerate these transient alterations; however, tissue flaps, which have a fragile blood supply, and other ischemic tissues eg, moderate-to-severe peripheral artery disease might be vulnerable to smoking-induced reductions in blood flow.

With respect to other effects of nicotine, both impaired and stimulated wound healing have been identified in experimental studies; however, no clinically significant detrimental or beneficial effects on wound healing have been demonstrated with the use of nicotine replacement therapies [ ]. AGING — Skin is not excluded from the complex processes of aging.

The supply of cutaneous nerves and blood vessels decreases with age, in addition to a general thinning of tissue, including the dermis and basement membrane. There is a progressive loss of collagen and diminished ability to produce more collagen.

These physiologic changes associated with aging contribute to slowed or impaired wound healing in older adults [ 35,36 ]. In several studies, the extremes of age infants and older individuals were identified as a risk factor for surgical site infection SSI [ 37 ]. One cohort study of more than , adult surgical patients found that increasing age independently predicted an increased risk of SSI only until age 65 years risk increasing 1.

See 'Infection' above and "Overview of perioperative nutrition support", section on 'Consequences of malnutrition in surgical patients' and "Overview of the evaluation and management of surgical site infection".

Thus, we generally prefer to screen for malnourishment by obtaining preoperative serum prealbumin and albumin levels in potentially high-risk patients and monitoring them to optimize nutritional status. Prealbumin and albumin are not perfect markers of nutritional status; however, these should be obtained on patients with nonhealing wounds [ 43 ].

In addition, measures of frailty and functional status may be linearly related to malnutrition and might also be incorporated into an assessment [ 44,45 ]. These are typically pressure wounds, similar in pathogenesis and appearance to neuropathic wounds occurring in areas of bony prominence such as the sacrum, knees, ankle malleoli, and heels.

The sacrum may be particularly at risk when the presence of incontinence in spinal cord patients leads to a moist environment [ 46 ]. See "Epidemiology, pathogenesis, and risk assessment of pressure-induced skin and soft tissue injury".

Immobilization in the absence of pressure is probably not a risk factor for wound development or chronicity. In fact, complete immobilization with total contact casting is an effective treatment for plantar diabetic foot ulceration [ 47 ]. The inflammatory phase of wound healing may be blunted in patients on long-term immune suppression such as is used in treating transplant patients and HIV patients, among others.

Chemotherapy — The administration of chemotherapy may have a detrimental effect on wound healing, specifically through its direct or indirect effects on vascular endothelial growth factor VEGF. VEGF is an important factor contributing to angiogenesis during the early stages of wound healing but may also be an important regulator in malignancy and thus is a target of cancer therapy [ 52 ].

See "Toxicity of molecularly targeted antiangiogenic agents: Non-cardiovascular effects", section on 'Delayed wound healing' and "Toxicity of molecularly targeted antiangiogenic agents: Non-cardiovascular effects", section on 'Cutaneous toxicity'.

Furthermore, neuropathy secondary to chemotherapy can produce loss of protective sensation and instability in a similar manner to diabetes. Glucocorticoids — Glucocorticoids may not have the same degree of negative effect as other immunosuppressive therapies, and locally applied topical steroids are often used in the treatment of chronic wounds [ 53 ].

While some degree of anti-inflammation may prevent wounds from becoming arrested in the inflammatory stage, significant suppression of inflammation can prevent wounds from progressing into the next stages of wound healing. This is a subjective and currently unquantifiable inflammatory balance [ 54,55 ].

Several studies have demonstrated the potential beneficial effects of topical steroid application in the treatment of chronic wounds, particularly when an abnormal and uncontrolled inflammatory stage is suspected within the stages of wound healing.

Radiation — Radiation therapy has evolved as a powerful tool for tumor control as a sole therapy or administered adjunctively.

More than 50 percent of cancer patients receive some form of radiation treatment, and, despite improvements in radiation technique, radiation-induced injury still contributes to poor wound healing. The term "radiation injury" refers to the morphologic and functional changes that can occur in noncancerous tissue as a direct result of ionizing radiation and may include apoptosis cell death with low doses of radiation or outright tissue necrosis with higher doses of radiation.

Irradiated skin in the chronic stage is thin, hypovascular, extremely painful, and easily injured by slight trauma or infection [ 56 ]. See "Clinical manifestations, evaluation, and diagnosis of acute radiation exposure", section on 'Cutaneous'. Skin ulcers due to radiation injury are more commonly delayed in presentation and are due to ischemic tissue changes.

Characteristic features of delayed radiation injury include telangiectasia and eccentric myointimal proliferation in the small arteries and arterioles. The proliferative changes may progress to obstruction, or the lumen may thrombose.

These ulcers heal very slowly and may persist for several years. Given the changes that are known to occur with respect to the perfusion of irradiated tissue and the phases of wound healing, surgical incisions in these locations are more likely to develop a wound complication.

If an incision is planned in an area of radiation exposure, the optimal timing for surgery remains unclear.

While some have recommended waiting three to six weeks after radiation therapy to perform an incision or conversely to delay radiation therapy three to four weeks after an incision, surgery in the immediate perioperative period has been reported [ 57,58 ].

It is likely that the dosing and duration of radiation therapy affects this decision making, preventing the ability to make generalized recommendations; each case needs to be individualized. DIABETES — Numerous cytologic factors contribute to impaired wound healing in patients with diabetes [ 59 ].

These include decreased or impaired growth factor production, angiogenic response, macrophage function, collagen accumulation, epidermal barrier function, quantity of granulation tissue, keratinocyte and fibroblast migration and proliferation, number of epidermal nerves, bone healing, and abnormal balance between the accumulation of extracellular matrix components and their remodeling by matrix metalloproteinases.

Diabetes is a particularly important risk factor for the development of chronic wounds from neuropathy and vasculopathy, which increase the risk of infection and delay healing [ 8,60 ]. Diabetes is frequently associated with peripheral artery disease PAD with atherosclerosis developing at a younger age and affecting more distal arteries below the knee eg, popliteal, tibial arteries.

PAD in combination with diabetic neuropathy contributes to higher rates of nonhealing wounds and limb loss in diabetic patients compared with those without diabetes [ 61,62 ]. Up to one-third of people with diabetes in the United States will develop a foot ulcer [ 60,63,64 ].

Peripheral artery obstruction is present in approximately 20 percent of these patients and diabetic neuropathy in up to 50 percent of these patients [ 56,60 ].

Neuropathy alone can be responsible for the development of diabetic foot ulcers. Neuropathy associated with diabetes affects sensory, motor, and autonomic nerves. Sensory neuropathy diminishes the perception of pain that is protective when tissue injury has occurred [ 65 ]. Patients with diabetes may not be aware of the injury, particularly if the injured region cannot be seen or if the patient has a visual impairment.

The motor nerves to the intrinsic muscles of the foot are affected in approximately 50 percent of patients with diabetes, resulting in claw deformities in the digits that transfer pressure to the plantar metatarsal heads.

Increased local tissue pressure on the plantar surface or in other regions where bony deformities contact the shoe may lead to skin erosion and ulceration that may go unnoticed in patients with sensory deficits. In addition, autonomic neuropathy causes the skin to become dry and susceptible to skin fissures, tearing, and infection due to a loss of sweat and oil gland function.

Loss of vascular tone may lead to foot edema [ 66 ]. Peripheral artery disease — Peripheral artery disease PAD with multilevel arterial obstruction decreases arterial blood flow, diminishes the delivery of oxygen and nutrients to the tissues, and impairs removal of metabolic waste products.

Limb-threatening ischemia develops when blood flow is insufficient to meet the metabolic demands of tissue at rest and manifests clinically with extremity pain, nonhealing wounds picture 1 , or tissue loss [ 1,2 ]. There is no single cutoff or perfusion threshold for limb-threatening ischemia, as the condition is a spectrum.

The presence of concomitant factors such as diabetes, renal failure, nutritional status, the complexity and extent of the wound, and recent or concomitant wound infection may require greater perfusion than expected to heal a given wound, particularly for foot wounds in patients with diabetes.

For this reason, blood flow should be assessed in all such wounds and graded as part of a spectrum of ischemia that may require revascularization to expedite wound healing [ 8 ]. The ankle-brachial index is widely considered to be an appropriate baseline test for this assessment.

See "Clinical features and diagnosis of lower extremity peripheral artery disease" and "Upper extremity atherosclerotic disease". Chronic venous insufficiency — Venous leg ulcers account for approximately 40 percent of wounds of the lower extremity [ 59 ].

An understanding of the normal anatomy and physiology of the venous return to the heart is essential for understanding the defects present in patients with chronic venous disease and ulceration. See "Pathophysiology of chronic venous disease".

Faulty vein valves, venous obstruction, or failure of the "venous pump" leads to abnormally directed flow from the deep to superficial venous systems via the perforating veins. The most common site of incompetent perforators is 5 to 10 cm above the medial malleolus [ 63 ].

Congestion and pooling of blood in the superficial veins leads to venous hypertension, which, if sustained, is associated with histologic changes in the vein wall. See "Pathophysiology of chronic venous disease", section on 'Histologic changes'.

EDEMA — Peripheral edema can be caused by a variety of conditions, but regardless of the etiology, the accumulation of interstitial fluid reduces the integrity of the skin and subcutaneous tissue, making it prone to injury.

The increased interstitial pressure also impairs the capillary diffusion and cellular function required as part of the normal tissue healing process, contributing to impaired healing when wounds do occur. See "Pathophysiology and etiology of edema in adults". OBESITY — Obese individuals have a higher incidence of wound complications, including seroma, hematoma, wound infection, and wound dehiscence, as well as a higher incidence of pressure ulcers and venous ulcers.

The etiology of wound complications in obese individuals is multifactorial, involving both local and systemic factors. Locally, factors contributing to poor wound healing include relative hypovascularity of the subcutaneous adipose tissue, which may also reduce antibiotic delivery and increase wound tension.

Poor skin perfusion also makes obese individuals susceptible to pressure injury, which can be aggravated by difficulties in repositioning and increased shear forces during movement.

LESS COMMON FACTORS — Other etiologies that can impair wound healing or lead to skin breakdown and chronic ulceration include conditions that cause vascular inflammation, obstruction, or thrombosis at the microvascular level.

The final common pathway that produces ulceration or poor wound healing in these disorders is tissue ischemia. See 'Impaired wound healing' above and "Approach to the differential diagnosis of leg ulcers". Sickle cell disease — Sickle cell disease represents a form of local tissue ischemia occurring at the specific location of the wound.

It is also obstructive in nature, similar to peripheral artery disease, but is caused by dysmorphic red blood cells physically occluding small vessels, usually of the lower extremities. The location and appearance of sickle cell wounds may be similar to ischemic and venous ulcerations.

A peripheral blood smear may be helpful in making the diagnosis. Treatment of these wounds is similar to the treatment of other chronic wounds, but sickle cell wounds are known to progress much more slowly through wound healing and carry an increased risk of reoccurrence [ 67 ].

See "Overview of the clinical manifestations of sickle cell disease", section on 'Leg ulcers'. Others — Other conditions associated with impaired wound healing include cholesterol embolism, vasculitis, pyoderma gangrenosum, polyarteritis nodosum, scleroderma, cryoglobulinemia, granulomatosis with polyangiitis, thromboangiitis obliterans, warfarin-associated necrosis, heparin-induced thrombocytopenia, protein C deficiency, protein S deficiency, and antiphospholipid antibody syndrome.

The cutaneous manifestations of these diseases can be found in separate topic reviews. SOCIETY GUIDELINE LINKS — Links to society and government-sponsored guidelines from selected countries and regions around the world are provided separately.

See "Society guideline links: Chronic wound management". Wounds may be caused by a variety of mechanisms, including acute injury abrasion, puncture, crush , surgery, or other factors that cause breakdown of previously intact skin eg, ischemia, pressure.

There is no specific time frame that distinguishes between acute and chronic wounds. These chemoattractants, including vascular endothelial growth factor VEGF , platelet-derived growth factor PDGF , and fibroblast growth factor FGF , as well as cytokines, promote the migration of inflammatory cells to the wound.

After approximately 24 to 48 hours, vasodilation occurs, allowing for inflammatory cells such as neutrophils, monocytes, macrophages, and lymphocytes to arrive at the injured tissue and perform a host of different functions.

Neutrophils are the first of the inflammatory cells to arrive, peaking at 24 hours. They phagocytize bacteria, clear microbial and other cellular debris. Also, polymorphonuclear leukocytes PMNs release reactive oxygen species that potentiate this killing process [8]. The next major step in wound healing involves the accumulation of macrophages, usually around 48 to 72 hours [8].

Macrophages help initiate the proliferation phase of the WHP. These cells also perform a variety of diverse functions, including promoting the inflammatory healing process through the release of cytokines, clearance of cellular debris, and attracting blast cells to the area of the wounding [8].

T-lymphocytes also play a critical but still poorly understood role, as their absence in the wound or delayed arrival has been associated with WHP impairment. As the proliferation phase gives way to remodeling, fibroblasts lay down the extracellular matrix ECM and allow for re-epithelialization of the wound.

Fibroblasts produce components of the ECM, including collagen-glycosaminoglycan scaffolds and proteoglycans [8]. Furthermore, endothelial cells promote angiogenesis and formation of a new capillary bed to allow for continued remodeling [8].

Myofibroblasts promote wound contracture via actin filaments. The WHP is very complex and involves high levels of coordination between multiple tissues and cell types [6]. Consequently, impairment in the process can occur at any step along the sequence that leads to process completion.

Many known factors can affect or modulate wound healing [7]. In the subsequent sections, we will discuss major modulators both positive and negative of the WHP, including a summary of some of the methods and techniques devised to promote wound healing [9].

There is no doubt that diabetes plays a detrimental role in wound healing. It does so by affecting the WHP at multiple steps.

Wound hypoxia, through a combination of impaired angiogenesis, inadequate tissue perfusion, and pressure-related ischemia, is a major driver of chronic diabetic wounds [10]. Ischemia can lead to prolonged inflammation, which increases the levels of oxygen radicals, leading to further tissue injury.

Elevated levels of matrix metalloproteases in chronic diabetic wounds, sometimes up to times higher than acute wounds, cause tissue destruction and prevent normal repair processes from taking place [10].

Furthermore, diabetes is associated with impaired immunity, with critical defects occurring at multiple points within the immune system cascade of the WHP. For example, neutrophils show impaired chemotaxis and phagocytosis. As a result, diabetic wounds are prone to chronic infection due to inadequate bacterial clearance [10].

To further complicate matters, these wounds have defects in angiogenesis and neovascularization. Normally, wound hypoxia stimulates mobilization of endothelial progenitor cells via vascular endothelial growth factor VEGF [8]. In diabetic wounds, there are aberrant levels of VEGF and other angiogenic factors such as angiopoietin-1 and angiopoietin-2 that lead to dysangiogenesis [11].

Diabetic neuropathy may also play a role in poor wound healing. Lower levels of neuropeptides, as well as reduced leukocyte infiltration as a result of sensory denervation, have been shown to impair wound healing [10].

When combined, all these diverse factors play a role in the formation and propagation of chronic, debilitating wounds in patients with diabetes. Cigarette smoking leads to numerous adverse health consequences, including various types of cancer, primary lung disease, and cardiovascular disease, among others [12] [13].

However, in addition to those, smoking has severe ill-effects on the WHP [14]. This occurs through multiple pathways, but most have the common theme of inducing wound ischemia. For example, nicotine in smoke acts as a vasoconstrictor.

Also, tobacco use stimulates the release of catecholamines such as epinephrine, leading to further reductions in tissue blood flow and hypoxia [15]. Relative wound ischemia can also result from the development of chronic obstructive pulmonary disease, which can lead to the permanent lowering of oxygen tension in the blood.

Carbon monoxide CO in cigarette smoke binds to hemoglobin with times greater affinity than oxygen, so even small amounts of carbon monoxide can profoundly reduce the oxygen carrying capacity of hemoglobin.

CO binding to hemoglobin will cause a leftward shift of the oxyhemoglobin dissociation curve, leading to less oxygen unloading at the tissue level [16] [14] [16]. In addition to the induction of ischemia, smoking leads to immunopathy of the wound via impaired PMN migration into the wound.

Fibroblast migration and proliferation are also hindered, leading to decreased production of ECM and ultimately weaker scar formation.

Not surprisingly, patients who stop smoking show improvement in wound healing [17]. The nutritional needs of the healing wound are very complex. Wounds require a myriad of different micro and macronutrients to heal properly [18].

Among amino acids of importance to the WHP, arginine, and glutamine play a critical in the overall process. Arginine improves immune function, supports collagen deposition as a precursor to proline , and plays a role in neovascularization.

Arginine supplementation also has a positive effect on wound healing. Glutamine is a critical energy source in proliferating cells e. This amino acid is thought to improve the overall wound strength by increasing levels of mature collagen.

The 2 other major macronutrients, fatty acids and carbohydrates, are also critical to wound healing. Carbohydrates, primarily glucose, act as the primary fuel for cells as it becomes broken down to form adenosine triphosphate ATP.

Polyunsaturated fatty acids, such as omega-3 and omega-6 fatty acids, both of which are essential fatty acids, may enhance the WHP by having an overall positive effect on host immune function [19] [20].

Several micronutrients are worth mentioning because they play a particularly important role in wound healing [21]. These include ascorbic acid, or vitamin C, vitamin A, vitamin E, as well as magnesium, zinc, and iron.

Vitamin C supports the hydroxylation of proline to hydroxyproline, which is essential for proper collagen formation. Vitamin A similarly supports collagen formation, as well as immune modulation, and decreased metalloprotease ECM degradation. As an antioxidant, vitamin E helps protect against oxidative tissue destruction, as well as may decrease excess scar formation.

Magnesium is a cofactor in enzymes involved in collagen synthesis. Zinc, on the other hand, is a cofactor for DNA and RNA polymerase, playing a vital role in cell division. Finally, iron deficiency has been shown to result in impaired collagen synthesis.

Further discussion of the most critical among the above micronutrients is provided at the end of this manuscript [22]. Obesity is a significant factor in surgical wound healing.

Abdominal obesity is correlated with oxidative stress, a phenomenon associated with deficiency of adiponectin e. Adiponectin-deficient state leads to impaired perfusion and reepithelialization of the wound.

Moreover, hypovolemia combined with relative hypoperfusion and reduction in oxygen delivery lead to further tissue injury. Consequently, wound complications, including surgical site infections and fat necrosis are more prevalent in obese patients.

Various combinations of the same factors may be associated with impaired secondary healing following primary wound-related morbidity [23].

Pressure ulcers are more likely to develop in obese patients through pressure-related ischemia and hypovascularity, as well as decreased mobility. Contact between the skin and various hospital surfaces e. Systemic effects of obesity, such as hypertension, hyperglycemia, and upregulation of the stress hormones in response to the physiologic burden of surgery and acute illness, all work to impair further wound healing.

Additional factors involved in this complex process include blunting of the immune and inflammatory responses. Interestingly, these ill-effects of obesity are largely reversible through weight loss [24]. Stress has been demonstrated to be a major contributor to a broad range of health conditions and illnesses, including cardiovascular disease, cancer, and obesity.

Stress states lead to upregulation of stress hormones via the hypothalamic-pituitary axis and the release of adrenocortical hormones.

Resultant changes include elevated levels of cortisol, glucocorticoids, and catecholamines. Cortisol works to blunt the immune response by blocking the production of important cytokines such as IL-1beta, IL-6, and TNF-alpha.

The impairment of immune response ultimately leads to deficient wound healing [25] [26]. Wound healing is a vast topic area, with many aspects remaining poorly understood despite the tremendous amount of progress over the past few decades.

Various co-morbid conditions e. More recently, a better understanding of the role micronutrients play in wound healing, along with the introduction of novel wound care therapeutics e. Numerous wound management devices have been introduced over the years to improve wound healing.

However, none have been as influential and successful as negative pressure wound therapy NPWT therapy. NPWT involves the application of subatmospheric pressure on wound via a sponge-based system with an airtight seal directly over the wound, connected under sealed conditions to a suction device.

Benefits of NPWT are realized via several different mechanisms. First, the subatmospheric pressure applied to the wound helps to remove wound exudate and other materials that are known to impair the WHP.

Secondly, the presence of subatmospheric pressure promotes angiogenesis and tissue perfusion by increasing cellular proliferation and migration into the wound.

The suction also assists in bringing wound edges together. When combined, all of the above elements and mechanisms work synergistically to help speed up wound healing. NPWT devices can be used on a wide variety of wounds, such as pressure ulcers, large abdominal wounds, traumatic wounds, as well as complex, difficult-to-cover tissue defects following debridement operations e.

Of note, NPWT is contraindicated in certain situations, such as wound surfaces involving malignancy, untreated osteomyelitis, non-enteric and unexplored fistulae, and necrotic tissue with eschar e. It has long been known that Vitamin A may have beneficial effects on wound healing in the setting of previous systemic exposure to corticosteroids.

More specifically, Vitamin A has been shown to overcome the inhibitory effects of cortisone and related corticosteroids on the rate of gain in tensile strength of the wound [34] [35] [34]. This may be especially pronounced in early stages of the WHP.

At the same time, Vitamin A by itself does not seem to be a significant modulator of the WHP, suggesting that its beneficial action in the setting of prior corticosteroid use is related to the interaction s specific to corticosteroid-specific pathway s [36] [37] [36].

Vitamin C and zinc have both been found to improve wound healing characteristics, although clinical adoption and implementation of this therapeutic combination is less than universal. Mechanistically, vitamin C has several favorable effects on the WHP. First, it is a powerful antioxidant and free radical scavenger.

Second, it is important to systemic immunity, and along with Zinc helps boost the immune system when taken in the postoperative period. Together with Arginine and Zinc, Vitamin C is important for collagen synthesis.

The evidence is strongest for supplementing vitamin C and zinc during the immediate postoperative period [38] [39] [40] [38]. Among other interesting and important developments in wound care, there is evidence that vitamin-D supplementation may help positively modulate impaired wound healing, although further research toward mechanistic understanding is required in this area.

More specifically, the role of vitamin D in the WHP may be indirect, through beneficial effects on closely related physiological processes, such as glucose homeostasis [41] [42].

Finally, another vast topic area that is worth mentioning but too extensive to fully discuss in this review is the use of growth factors in the modulation of the WHP.

It has been demonstrated that delivery of various specific growth factors e. Further research is required to better define mechanisms of action, potential side effects, and the overall risk-benefit of human application of such therapies.

While considered by many as archaic, maggot debridement therapy MDT has been shown unequivocally to be of benefit in wound healing [46] [47]. MDT is based on the observation that fly larvae only debride dead, devitalized, and necrotic tissue. Healthy, viable tissue is not threatened during the MDT, making this therapy uniquely suited for debridement of devitalized tissues with truly surgical precision [48].

In fact, MDT is considered a form of "biosurgery. This liquefied material is then ingested, resulting in effective debridement of the tissue of interest. It has been shown that MDT can help debride large wounds in as little as 72 hours, resulting in a viable granulation bed that is suitable for conventional wound management.

In addition to chemical debridement, larval secretions are also characterized by significant antimicrobial activity, active against a wide range of pathogenic and often antibiotic-resistant bacteria, mostly gram-positive species.

Maggots work best on moist environments with sufficient oxygen supply [49]. They are approved for use in non-healing necrotic skin and soft tissue wounds, pressure and venous stasis ulcers, neuropathic foot ulcers, and non-healing traumatic or surgical wounds [50].

Most recent developments in this area include the introduction of transgenic maggots that secrete human growth factors in their saliva [51]. Clinical applications of this therapy are continually expanding. Of interest, application of MDT can be accomplished through direct exposure of the maggots to the wound bed using a specialized "housing" or through indirect exposure using larvae contained within a sealed, semi-permeable bag [52] [53].

Hyperbaric oxygen therapy HBOT is another treatment modality that has been around for quite some time, but only recently saw a resurgence in interest due to promising effects on the WHP, especially in the setting of chronic and complicated wounds [54] [55].

Chronic wounds, often seen as a consequence of diabetes, arterial or venous disease, are increasingly common and result in significant impact on the affected patients, their caretakers, and the healthcare system in general.

The beneficial action of HBOT on wound healing is predicated on the increased supply of oxygen to wounds that are refractory to other, more conventional treatment approaches [56].

In practice, HBOT involves the patient being temporarily enclosed in a special chamber that in many ways approximates conditions used for deep sea divers and involves gradual "dive" followed by a pre-defined time interval at a certain "oxygen pressure level," and subsequent gradual "resurfacing" process.

While in the chamber, the patient is exposed to markedly elevated concentrations of pure oxygen, leading to elevation of systemic and tissue oxygen levels. It has been demonstrated that HBOT is effective in improving the course of chronic diabetes-related extremity wounds, potentially reducing the need for major but not necessarily minor amputations.

Available evidence suggests beneficial effects of HBOT on wounds are usually apparent within approximately 6 weeks of therapy, but long-term beneficial effects continue to be questionable. Another area where HBOT can be beneficial is the management of necrotizing soft tissue infections e.

Additional difficult-to-treat types of wounds that have been speculated to benefit from HBOT are the chronic pressure ulcers due to its inherently "ischemic" nature and venous ulcers; however, there is no solid evidence to support HBOT for either of these indications at this time [57] [60].

The best management of wounds is taken care of by an interprofessional team of a nurse specializing in wound care and a clinician with significant wound experience. Caring for wounds not only involves regular follow-ups but patient education.

A coordinated team approach has been shown to be most effective in wound management. Disclosure: Brian Wernick declares no relevant financial relationships with ineligible companies.

Impaired wound healing -

Positioning and elevation of the edematous body part to promote venous return and diminish congestion improve tissue perfusion. Assist in preparing the client for hyperbaric oxygen therapy.

Hyperbaric oxygen therapy involves either the application of topical oxygen at increased pressure directly to the wound or placing the client into a hyperbaric oxygen chamber.

Both methods of hyperbaric oxygen therapy promote wound healing by stimulating new vascular growth and aiding in the preservation of damaged tissue.

Administer muscle relaxants for spasticity or prepare the client for surgery. Spasticity should be controlled pharmacologically with medications such as diazepam , baclofen, or dantrolene sodium.

Clients with spasticity refractory to medication may be candidates for neurosurgical ablation. Provide oral nutritional supplementation as recommended. Malnutrition is one of the few reversible contributing factors for pressure injuries.

Prepare the client for surgical procedures as indicated. Surgical intervention is necessary when the injury is extensive when complications exist, and when the ulcer does not respond to treatment.

Surgical procedures include debridement, incision and drainage, bone resection, and skin grafting. Osteomyelitis is a common complication of wounds of stage IV depth.

Assist during urinary or fecal diversion procedures as indicated. Urinary or fecal diversion may be necessary to optimize wound healing. Prepare the client for the reconstruction of pressure injury as indicated. Reconstruction of a pressure injury is aimed at the improvement of client hygiene and appearance, prevention or the resolution of osteomyelitis and sepsis, reduction of fluid and protein loss through the wound, and prevention of future malignancy.

Educating clients and caregivers about wound care and skin integrity empowers them to take an active role in their own care. By providing knowledge bout proper wound cleaning, dressing changes, and preventive measures, individuals can confidently perform self-care activities and actively contribute to their healing process.

Educate the client about proper nutrition, hydration, and methods to maintain tissue integrity. The client needs proper knowledge of their condition to prevent impaired tissue integrity. Teach the client and caregiver about skin and wound assessment and ways to monitor for signs and symptoms of infection, complications, and healing.

Early assessment and intervention help prevent the development of serious problems. Signs of a localized wound infection include redness, warmth, and tenderness around the wound. Instruct client, significant others, and family in the proper care of the wound, including handwashing , wound cleansing, dressing changes, and application of topical medications.

Nursing management for clients who must perform self-care for skin problems, such as applying medications and dressings, focuses on educating the client about how to cleanse the affected area and pat it dry, apply medication to the lesion while the skin is moist, cover the area with plastic if recommended, and cover with an elastic bandage, dressing, or paper tape to seal the edges.

Educate the client on the need to notify the healthcare provider or nurse. This is to prevent further impaired tissue integrity complications. New signs of infection should be reported to the healthcare provider with an anticipated order for a wound culture. Inform the client or caregiver against elevating the head of the bed repeatedly.

Encourage the use of lifting devices like trapeze or bed linen to move the client in bed. The common cause of impaired skin integrity is friction which involves rubbing heels or elbows toward bed linen and moving the client up in bed without the use of a lift sheet.

Educate the client and caregiver about the causes of pressure. This information can assist the client or caregiver in finding methods to prevent skin breakdown. The development of pressure injuries is directly related to the duration of immobility: if the pressure continues long enough, small vessel thrombosis and tissue necrosis occur, and a pressure injury results.

Reinforce the importance of turning, mobility, and ambulation. These will enhance their sense of efficacy and can improve compliance with the prescribed interventions. When a person is immobile and inactive, pressure is exerted on the skin and subcutaneous tissue by objects on which the person rests, such as a mattress, chair seat, or cast.

Educate clients and caregivers about proper skin care. Educating clients and caregivers on methods to maintain skin integrity enhances their sense of self-efficacy and prevents skin breakdown. Continuous moisture on the skin must be prevented by meticulous hygiene measures.

It is important to pay special attention to skin folds, including areas under the breasts, arms, and groin, and between the toes. The skin may be lubricated with a bland lotion to keep it soft and pliable.

Drying agents and powders are avoided. Educate the client to inspect pressure areas routinely. When decreased sensory perception exists, the client and caregivers are taught to inspect potential pressure areas visually every morning and evening, using a mirror if necessary, for evidence of pressure injury development.

Reinforce the importance of regularly checking diapers and incontinence pads in immobile clients. Diapers and incontinence pads may be useful in absorbing moisture away from the surface of the skin, provided that they are checked regularly and changed when soiled. The nurse must instruct the family to be alert for environmental factors that may contribute to pressure on the skin and diminished circulation such as wrinkles in sheets or pressure of tubes on the skin, and remove the source of pressure.

Ensure that the client has a strong support system at home. Clients and their support system must realize that it is their responsibility to avoid recurrent and new ulceration and that this is a lifelong process.

Client and Caregiver Education Recommended Resources See also References and Sources What is tissue integrity? Phases of wound healing When skin is injured, there are four phases of wound healing that take place: hemostasis, inflammatory, proliferative, and maturation.

In the hemostasis phase, platelets release growth factors that alert various cells to start the repair process at the wound location. This phase lasts up to 60 minutes, depending on the severity of the injury. After the hemostasis phase, the inflammatory phase begins, wherein vasodilation occurs so that white blood cells in the bloodstream can move into the wound to start cleaning the wound bed.

This appears as edema, erythema, and exudate to the observers. The proliferative phase begins within a few days after the injury and includes four important processes: epithelialization, angiogenesis, collagen formation, and contraction.

Epithelialization refers to the development of new epidermis and granulation tissue, which is a new connective tissue with new, fragile, thin-walled capillaries. Angiogenesis occurs when capillaries begin to develop within the wound 24 hours after injury.

These capillaries bring more oxygen and nutrients to the wound for healing. Collagen is formed to provide strength and integrity to the wound. At the end of the proliferation phase, the wound begins to contract in size. During this phase, collagen continues to be created to strengthen the wound.

A wound typically heals within four to five weeks and often leaves behind a scar. Types of wound healing There are three types of wound healing: primary intention, secondary intention, and tertiary intention.

Primary intention. This means that the wound is sutured, stapled, glued, or otherwise closed so the wound heals beneath the closure. This type of healing occurs with clean-edged lacerations or surgical incisions.

Closed edges are referred to as approximated. Secondary intention. This occurs when the edges of a wound cannot be approximated or brought together, so the wound fills in from the bottom up by the production of granulation tissue.

Examples of this type are pressure injuries and chainsaw injuries. These are at a higher risk of infection. Tertiary intention. This refers to a wound that has had to remain open or has been reopened, often due to severe infection. The wound is typically closed at a later date when the infection has resolved.

Nursing Care Plans and Management Effective wound care and the maintenance of skin integrity are vital aspects of nursing care. Nursing Problem Priorities The following are the nursing priorities for clients with wounds or compromised skin integrity.

Wound assessment. Frequent wound assessment based on the type, cause, and characteristics of the wound is necessary to help determine the type of treatment required to manage the wound effectively and promote maximal wound healing. Effective wound care.

Quality wound care is important for rapid and uncomplicated healing through decreasing complications, repeated admissions, length of hospital stay, and costs, and enhancing client quality of life. Proper suture and staple removal. Proper timing and technique in suture or staple removal prevent complications that may arise from a non-healed wound.

Drain management. The site and drain should be checked periodically throughout the shift to ensure the drain is functioning effectively and that no leaking occurs. Wound care for burns. Proper management of burn injuries is required to prevent wound deterioration.

Prevention and effective treatment are imperative to avoid developing or worsening pressure injuries. Client and caregiver education. Education empowers the client and their caregivers to actively participate in the healing process, promotes adherence to treatment plans, and fosters a proactive approach to preventing complications.

Nursing Assessment A thorough assessment of the skin or the wound must be conducted, including measurements of wound dimensions, evaluation of wound bed appearance, identification of any signs of infection, and assessment of surrounding skin integrity.

A break in tissue integrity is characterized by the following subjective and objective data: The affected area is hot, and tender to touch Damaged or destroyed tissue e. Nursing Goals Goals and expected outcomes may include: The client reports any altered sensation or pain at the site of tissue impairment.

The client demonstrates an understanding of the plan to heal tissue and prevent injury. The client describes measures to protect and heal the tissue, including wound care. Nursing Interventions and Actions Therapeutic interventions and nursing actions for clients with impaired skin integrity include: 1.

Type Types of wounds may include abrasions, lacerations, burns, surgical incisions, pressure injuries, skin tears, arterial ulcers, or venous ulcers. It is important to understand the type of wound present to select appropriate interventions. Location The location of the wound should be documented precisely.

A body diagram template is helpful to demonstrate exactly where the wound is located. Size Wound size should be measured regularly to determine of the wound is increasing or decreasing in size.

Length is measured using the head-to-toe axis, and width is measured laterally. Degree of tissue injury Wounds are classified as partial-thickness or full-thickness. For pressure injuries, it is important to assess the stage of the injury see Management of Pressure Injuries.

Color of the wound base Assess the base of the wound for the presence of healthy, pink, or red granulation tissue. Note the unhealthy appearance of dark red granulation tissue, white or yellow slough, or brown or black necrotic tissues.

Drainage The color, consistency, and amount of exudate or drainage should be assessed and documented at every dressing change. Murphree, Assess the skin for dermatitis or exposure to chemical irritants These conditions can cause inflammation, resulting in redness, and itching, and may cause blisters.

Providing Effective Skin and Wound Care There are much more opportunities to protect and enhance skin integrity from the outside. Promoting skin integrity Clean, dry, and moisturize skin, particularly bony prominences, twice daily or as indicated by incontinence or sweating.

Providing wound care Provide wound care as needed. Polyhexamethylene biguanide When PHMB attaches to the acid membrane elements of the bacteria, the bacteria subsequently lose fluidity, causing the separation of the individual membrane lipids and dissolution of the bacterial cell. This bactericidal mechanism means there are no residual organisms left alive to facilitate resistance.

PHMB has been combined in gauze and foam dressing formats. They are best utilized for healable surface wounds with exudate. Silver Silver is ideally suited to healable wounds with critical colonization.

It is an antibacterial agent in an ionized form that can attack cell membranes, cytoplasmic organelles, and DNA, so resistance is uncommon. Silver is most often combined with calcium alginates, hydrofibers, foams, and hydrogels. Iodine Iodine has several antimicrobial actions including blocking bacterial cell efflux pumps, interfering with cellular respiratory processes, changing DNA structure, and denaturing cellular proteins and enzymes.

Iodophors are safer-slow-release iodine delivery systems. The two most commonly used are povidone-iodine and cadexomer iodine. Clients on iodine for large wounds or extended periods should have thyroid function tests at regular intervals as hypothyroidism or hyperthyroidism can be induced by iodine wound dressings.

Methylene blue and crystal violet foam dressings This product is a relatively non-release foam dressing with two agents, MB and CV, which produce a redox environment inhibiting the growth and survival of bacteria. The original polyvinyl alcohol foam needs to be partially hydrated to bind the surface slough and provide autolytic debridement.

Honey Honey has been used in wound care for centuries because of its antibacterial and anti-inflammatory properties. Its acidic pH and high sugar content make the local wound environment hostile to bacteria.

Honey may lose its antibacterial action when diluted with wound exudate, but this may not increase the incidence of bacterial resistance. Medical-grade honey should be used instead of honey from food sources this is because bacterial spores can persist in honey and have the potential to cause disease if activated Sibbald et al.

Topical growth factor therapy This is a platelet-derived growth factor that recruits and stimulates fibroblast proliferation, promoting granulation tissue formation.

It is usually indicated for neuropathic diabetic ulcerations and wounds that extend to the subcutaneous tissues or deeper. This can be applied once daily to the wound bed. Acellular extracellular matrices These are non-living tissues derived from allogenic, xenographic, or synthetic sources that accelerate healing with minimized scar tissue formation.

These agents are indicated for partial and full-thickness wounds, burn wounds, traumatic wounds, and surgical wounds. They deliver exogenous growth factors to the wound bed and are antimicrobial and anti-inflammatory.

These allografts are indicated for acute and chronic wounds and non-healing wounds. They can be applied directly to the wound bed. Cell-based therapies These deliver exogenous growth factors to the wound bed with visible cells cultured on different bioabsorbable matrices.

Cell-based therapies can be epidermal, dermal, or bilayer therapies. These cells are removed from cell-based therapies including hair follicles, sweat glands, blood vessels, and immune cells. Proper Suture and Staple Removal Sutures are tiny threads, wire, or other materials used to sew body tissue and skin together.

Drain Management Drain management systems are commonly used during post-operative surgical management to remove drainage, prevent infection, and enhance wound healing. Assessment of burn injuries Evaluate the burn client using the ABCs. First-degree burns These are usually red, dry, and painful. Burns initially termed first-degree are often actually superficial second-degree burns, with sloughing occurring the next day.

Second-degree burns These burns are often red, wet, and very painful. Their depth, ability to heal, and propensity to form hypertrophic scars vary enormously. Third-degree burns These are generally leathery in consistency, dry, insensate, and waxy. These wounds will not heal, except by contraction and limited epithelial migration, with resulting hypertrophic and unstable cover.

Fourth-degree burns These burns involve underlying subcutaneous tissue, tendon, or bone. Emergency burn management Remove the source of flames. Irrigate chemical burns. Wound cleaning and dressing Cleanse and dress the wound gently and regularly.

Medication administration Apply topical antibacterials to burn wounds as indicated. Silver has a broad antibacterial spectrum and is painless upon application.

Aqueous 0. This has broad-spectrum coverage, including fungi; however, it leeches off electrolytes. Mafenide acetate. This agent has also broad antibacterial spectrum properties and can best penetrate eschars. This is a bland and nontoxic topical material.

Debriding enzymes. These enzymes are useful in selected partial-thickness wounds. Porcine xenograft This adheres to the wound coagulum and provides excellent pain control. Split-thickness allograft This graft vascularizes and provides durable temporary closure of the wounds.

Hydrocolloid dressings These provide a vapor and bacteria barrier while absorbing wound exudate. Impregnated gauzes These provide a vapor and bacteria barrier while allowing drainage.

Acticoat This is a nonadherent wound dressing that delivers a low concentration of silver for antisepsis. Biobrane A synthetic bilaminate that facilitates fibrovascular tissue growth into the inner layer and provides a temporary vapor and bacteria barrier.

Transcyte A synthetic bilaminate that facilitates fibrovascular tissue growth into the inner layer populated with allogenic fibroblasts and an overlying layer that provides a temporary vapor and bacteria barrier.

Alloderm R This consists of cell-free allogenic human dermis and requires an immediate thin overlying autograft. Surgical management of burns Assist in wound debridement as indicated.

There are four types of debridement: Natural debridement The devitalized tissue separates from the underlying viable tissue spontaneously. Bacteria present at the interface of the burned tissue and the viable tissue gradually liquefy the fibrils of collagen that hold the eschar in place.

The process may take weeks to months to occur. Mechanical debridement This involves the use of surgical tools to separate and remove the eschar. Dressing changes and wound cleaning aid in the removal of wound debris.

Wet-to-dry dressings are not advocated in burn care because of the possibility of removing viable cells along with necrotic tissue. Chemical debridement Topical enzymatic agents are available to promote the debridement of burn wounds.

Because such agents usually do not have antimicrobial properties, they may be used together with topical antibacterial therapy to protect the client from bacterial invasion.

Surgical debridement Early surgical excision to remove devitalized tissue along with early burn wound closure is now recognized as one of the most important factors contributing to the survival of a client with a major burn injury. This may be performed as soon as possible after the burn, once the client is hemodynamically stable and edema has decreased.

Ideally, the wound is then covered immediately with a skin graft and a dressing. Management of Pressure Injuries Once a pressure injury has developed, immediate treatment is required.

Assessment and classification of pressure injuries Classify pressure ulcers by assessing the extent of tissue damage.

The following are the stages of pressure ulcers: Stage I. Nonblanchable erythema signaling potential ulceration.

This leads to wound contraction and formation of the granulation tissue. New blood vessel formation - called angiogenesis - occurs simultaneously which facilitates the transport of oxygen and nutrients to the newly formed tissue.

In the final stage, type III collagen is remodeled and replaced with type Icollagen which has more tensile strength. Any factor or disease that can disrupt the normal stages of wound healing can lead to delayed wound healing.

Some of the factors are described below:. A common cause of delayed wound healing is infection. At the time of injury, microorganisms can enter the tissue. These microbes can delay wound healing by further prolonging the inflammatory process. Bacteria cause the release of pro-inflammatory cytokines which can inadvertently raise the levels of MMPs matrix metalloproteases , which are a family of enzymes that degrade the extracellular matrix.

This enzyme degrades the granulation tissue at the wound site, hence contributing to a delayed wound closure. The commonly associated bacteria with delayed wound healing are P.

aeruginosa and Staph Aureus. These bacteria tend to form 'biofilms' which are complex structures that resist antibiotics and degradation by the neutrophils. Without adequate wound care and decontamination, healing is extensively delayed in the setting of bacterial superinfection.

Collagen is an important constituent of granulation tissue and any nutritional deficiency that can affect its synthesis will lead to delayed wound healing.

Vitamin C, which is a cofactor required for collagen synthesis, and protein deficiency can negatively affect the wound healing process. When assessing chronic wounds, wound care specialists need to consider the nutritional status of their patients. Addressing these deficiencies can help improve wound healing.

Steroids are known for their potent anti-inflammatory effect and unfortunately, this effect can be destructive for wound healing. Inflammation is an essential step in wound healing.

As steroids inhibit the inflammatory process, they can halt normal wound repair. As a result, an inadequate amount of granulation tissue is produced. Steroids are also known to increase the risk of wound infections which leads to impaired wound healing.

Patients on long-term steroid use are also at an increased risk of developing diabetes, a metabolic syndrome that can further complicate the wound healing process.

Globally, million people are suffering from diabetes. The prevalence of diabetes is steadily rising, and diabetes-related complications are also expected to see an increase.

Diabetes contributes to wound chronicity through multiple mechanisms. Patients with diabetes experience low tissue blood supply which affects the oxygen and nutrient supply to the wound site.

As a consequence,wounds heal slowly. Moreover, diabetes also predisposes individuals to neuropathy or nerve damage which means that diabetic patients aren't always aware of any trauma they experience. Decreased tissue perfusion combined with neuropathic changes puts diabetic patients at an increased risk of developing chronic ulcers and wounds.

Diabetes is the single most likely cause of lower-limb amputations in the United States. To minimize these grim statistics, initial screening and management by podiatristsis vital. Podiatrists are well trained in the lower limb anatomy and are often the first to detect any initial ischemic or neuropathic changes.

They can formulate a comprehensive foot care plan, treatment, and follow-up for diabetic patients. Diabetic foot ulcers are complex and often require a multidisciplinary management approach. A comprehensive treatment plan led by vascular surgeons, podiatrists and endocrinologists can help significantly reduce the rate of amputations in diabetic patients.

Wounds require oxygen, nutrients, and proper blood supply for optimum healing. An adequate blood supply to the tissues is therefore essential. Peripheral vascular disease affects the blood supply to the extremities and is linked with the development of chronic wounds.
