Antidotative therapy for snakebite -
Below is US data reported to the National Poison Center Database from to annual average in parenthesis. Of interest, but no utility, the cottonmouth is sometimes called a water moccasin and the copperhead a highland moccasin.
Why moccasin? It is unknown but one rumor has it that neither the cottonmouth nor the copperhead are equipped with rattles like their cousin, thus move about quietly as do humans wearing moccasins.
And if you want to know how the venomous snakes really got their poison click here. In case of bite So what happens if you get bit? Or you are caring for the bitten? Take care of any immediate threats. Make sure the offending snake is not close by and remember that dead snakes may still have a bite reflex.
Assure the patient has an open airway and adequate respirations and be ready to intervene if necessary. If you are IV capable, start a line. Immobilize the bitten part if possible to slow absorption of venom.
Logic suggests that if the bite produces mostly local damage you would want to elevate above the heart to help prevent or decrease edema and additional tissue damage; but if the bite is producing systemic symptoms like shock or bleeding then perhaps the bitten part should be lowered to decrease venom absorption.
Or perhaps the best bet is to keep the involved body part level with the heart. That may be the most logical position because we may not be able to determine if the bite will progress one way or the other. Determine the time of the bite if possible.
Mark a spot above and below the bite and measure the circumference, note the time and repeat the measurement every minutes during transport if not too busy with more urgent treatment. The rate of progression of signs at the bite site and the development of systemic symptoms or signs will help determine if antivenom is indicated and the amount of antivenom administered.
However there is a dwindling supple of coral snake antivenom as the only company that manufactured the product has ceased production. Identify the snake without endangering yourself, like a cell phone photo or two.
And if you have that capability, take a picture of the bite site and note the time, then repeat if there is change. DO NOT cut, suck, shock, or freeze the bite site nor restrict blood or lymphatic flow in or out; these all makes it worse. However, for a neurotoxic snake bite it appears that a pressure immobilization wrap from below the bite to above the bite may be of benefit if done appropriately.

PRODUCT GUIDE. DEEP DIVE. Trending Topics Inside EMS. One for the Road. If no swelling has occurred within 1 hour and no systemic signs of envenomation are present, the bite was probably dry.
The venom of Mojave, timber, and canebrake rattlesnakes is primarily neurotoxic. Envenomation causes neurologic signs such as muscle fasciculations.
If a crotalid bite is not witnessed, it can be mistaken for other disorders. Differential diagnoses include trauma, abscess, bite wound from an animal other than a snake, spider bite, and allergic reaction to an insect bite.
The predominant signs of coral snake envenomation are neurologic, with minimal local swelling and pain. The onset of signs may be delayed for up to 18 hours. Signs include tetraparesis, weakness, ataxia, muscle fasciculations, tachypnea, shallow breathing, altered quiet mental state, hemolysis, anemia, and hemoglobinuria.
Puncture wounds from coral snakes may be difficult to find. Differential diagnoses for elapid envenomation include tick paralysis, botulism, and myasthenia gravis. Diagnostic testing includes a complete blood count, coagulation profile, chemistry panel, and urinalysis.
Anemia and thrombocytopenia can occur with both crotalid and elapid bites, and echinocytes may appear after rattlesnake and coral snake envenomation.
Coagulation deficits may or may not be accompanied by thrombocytopenia. Rhabdomyolysis can cause an increase in serum creatine phosphokinase.
Urinalysis may reveal hematuria, hemoglobinuria, or myoglobinuria. Pigmenturia indicates severe envenomation. Using a snakebite severity score is recommended to track the progression of signs and help decide whether antivenin is needed. Snake envenomation patients should be observed for at least 8 hours.
Rapid-acting corticosteroids, antibiotics, and antivenin are used in some cases. Antivenin may be indicated if swelling progresses rapidly, if coagulopathy or thrombocytopenia is present, or if the patient has signs of neuromuscular toxicity or shock.
Antivenin is often not needed for copperhead bites. Newer Fab antivenins have a lower risk of anaphylaxis but could be too expensive for veterinary patients. Treatment for coral snake envenomation consists of intravenous fluids, anticonvulsants, and respiratory support.
The prognosis for snakebite patients depends on the type of snake, degree of envenomation, size of the patient, location of the bite, and time before initiation of treatment. Severe crotalid envenomation can cause significant long-term effects secondary to tissue necrosis 3 ; limb edema may persist for months.

Snakebite envenomations SBEs Antidotative therapy for snakebite a Antidotativw medical condition of global importance that mainly affect the tropical Anti-cellulite properties subtropical regions. The threapy treatment for snake envenomations is antivenom, Theraly is produced from the hyperimmunization of animals with snake Energy balance and metabolism. The inhibition thedapy the Antidotatife of SBEs using natural or synthetic compounds has been suggested as a complementary treatment particularly before admission to hospital for antivenom treatment, since these alternative molecules are also able to inhibit toxins. Biodiversity-derived molecules, namely those extracted from medicinal plants, are promising sources of toxin inhibitors that can minimize the deleterious consequences of SBEs. In this review, we systematically synthesize the literature on plant metabolites that can be used as toxin-inhibiting agents, as well as present the potential mechanisms of action of molecules derived from natural sources. Matthew Lewin, founder therxpy the Center for Antidotative therapy for snakebite and Anti-cellulite properties Health at the Snakebiye Academy of Sciences, was researching forr treatments in rural Astaxanthin and eczema management in preparation Anti-cellulite properties an expedition to the Philippines in That set Lewin in Fr of a modern snakebite drug, a Antidotatibe that Antidotstive his Corte Madera, California, company, Ophirex, nearing a promising oral treatment that fits in a pocket; is stable, easy to use and affordable; and treats the venom from many species. His work has gotten a boost with multimillion-dollar grants from a British charity and the U. If it works — and it has been shown to work extremely well in mice and pigs — it could save tens of thousands of lives a year. Lewin and Ophirex are not alone in their quest. Snakebites kill nearlypeople a year, overwhelmingly in impoverished rural areas of Asia and Africa without adequate medical infrastructure and knowledge to administer anti-venom.Video
Dr. West's Tips on Snakebite TreatmentAntidotative therapy for snakebite -
It can help to joke about them getting a free ride just this once. Remove any rings or constricting items such as watches, bracelets, and tight-fitting clothing shoes too if the leg was bitten.
A properly stocked first aid kit should have a pair of surgical shears capable of cutting fabric. This purpose-made bandage features printed rectangles that stretch to form squares when the right amount of pressure is applied. See this video for instructions.
Venom spreads more quickly through the lymphatic system when the limb is allowed to move — something you should try to prevent if you have to move the patient yourself. To immobilise the limb, there are two things you can do: splint the bitten limb and carry the patient on a makeshift stretcher.
If you have a rope on you, you can make a stretcher using this and two branches. Shock is a real danger in the case of most snake bites, and if you see any signs of shock such as paleness setting in, you need to treat the patient immediately.
Lay the person flat, raise their feet slightly, and cover them with something — like a jacket or emergency blanket — to make them as comfortable as possible. Do not give the victim anything to eat or drink, and do not give them any medication. Do talk to them in a reassuring tone and try to calm them.
Only attempt to move the victim once signs of shock are no longer evident. You are not Steve Irwin. Do not go chasing reptiles into the bush. And even then, keep your distance. Cutting the victim would be worse in that it would raise the chances of secondary infection and could put the victim into shock.
Warm water does nothing to denature snake venom, so if you clean a wound, it will only be to prevent secondary infection. But know that traces of venom left on the skin can be used in combination with a snake bite identification kit to identify the species. Leaving the wound unwashed can make it easier to determine the right antivenom to administer.
A tourniquet can cut off blood flow completely and may result in the loss of the affected limb. Besides, venom is distributed through the lymphatic system and not veins. Do not give the patient painkillers, alcohol or caffeinated drinks. Antivenom, too, cannot be administered by a layman as it can bring on adverse side effects that have to be countered with other drugs.
Usually, if you leave a snake alone, it will leave you alone. That said, you also want to avoid the kind of surprise encounters that will make a snake feel threatened.
Be careful around tall grass and brush piles, and when scrambling around rocky areas and downed timber. Try to step onto and not over logs and rocks. At the Technical University of Denmark, Andreas Laustsen is looking at engineering bacteria to manufacture anti-venom in fermentation tanks.
The days of incising a snakebite and sucking out the poison are long over, but the current treatment for venomous snakebites remains archaic. A microscopic view of rattlesnake venom destroying cells. Matthew Lewin. Since the early s, anti-venom has been made by injecting horses or other animals with venom milked from snakes and diluted.
Hospitals in the U. A major problem is the roughly two hours it takes on average for a snakebite victim to reach a hospital and begin treatment. The chemical weapon that is venom starts immediately to destroy cells as it digests its next meal, making fast treatment essential to saving lives and preventing tissue loss.
Instead, he thinks of it as the first line of defense until the victim can reach a hospital for anti-venom treatment. Lewin said he expects the drug to be inexpensive, so people in regions where snakebites are common can afford it.
Venom is extremely complicated chemically, and Lewin began his search by sussing out which of its myriad components to block.
He zeroed in on the sPLA2 enzyme. Surveying the literature about drugs that had been clinically tested for other conditions, he came across varespladib.
It had been developed jointly by Eli Lilly and Shionogi , a Japanese pharmaceutical company, as a possible treatment for sepsis. They had never taken it to market. If it worked, Lewin could license the right to produce the drug, which had already been thoroughly studied and was shown to be safe.
He placed venom in an array of test tubes. Varespladib and other drugs were added to the venom. He then added a reagent. If the venom was still active, the solution would turn yellow; if it was neutralized, it would remain clear.
Matthew Lewin holds up a vial containing varespladib, a drug being tested for snakebite treatment. Varespladib may also help treat a respiratory condition caused by COVID Daniel Z. With a small grant, he sent the drug to the Yale Center for Molecular Discovery and found that varespladib effectively neutralized the venom of snakes found on six continents.
The results were published in the journal Toxins and sent ripples through the small community of snakebite researchers. Lewin then conducted tests on mice and pigs.
Both were successful. Human clinical trials are next, but they have been delayed by the pandemic. They are scheduled to get underway next spring. Along the way, Lewin was fortunate enough to make some good connections that led to funding. In , he attended a party at the Mill Valley, California, home of Jerry Harrison, the former guitarist and keyboardist for Talking Heads.
He became an investor and co-founder of Ophirex with Lewin. Lewin met Lt. Rebecca Carter, a biochemist who was assigned to lead the Medical Modernization Division of Air Force Special Operations Command, in when she attended a Venom Week conference in Greenville, North Carolina.
