All terrestrial elapids are mainly vertebrate predators; for example, Micrurus mainly eat snakes and lizards, Hemachatus anurans, and Dendroaspis eat birds and mammals. The α-neurotoxins can be subdivided into “short” (60–62 residues; four disulfides), and “long” (66–74 residues; five disulfides), including the κ-neurotoxins (66 residues; five disufides) and “weak” neurotoxins and other homologs (63–66 residues; five disulfides). The majority of viper and cobra venoms cause local pain, swelling and erythema. Wash the eyes and areas surrounding it immediately to stop the spread of permanent damage of the poison to the tissues. The sea krait is mainly nocturnal but sometimes forages during the day. These “muscle-type” receptors are pentameric proteins with two α subunits and one each of β, γ, and ε(or δ), and such receptors are powerfully blocked by the high affinity binding of both short and long α-neurotoxins. In recent years, counterfeit antivenins have appeared in Africa and Asia, possibly explaining recent increases in snake bite case fatality rates at several experienced African medical centers. Although bleeding is not a major consideration following elapid envenomation, victims have been reported to develop significant coagulopathies189,190 (Box 10). In developing regions, patients may succumb days to weeks after the bite, owing to complications such as renal failure, secondary wound infection, or failure of manual or mechanical ventilation. Many snakes of the same species have venom that may vary in potency and clinical effects across that species' range. In contrast, spider venom causes excessive release of acetylcholine, with resulting tetanic spasms followed by paralysis. Following successful resuscitation and antivenin treatment, patients should be monitored for sequelae of envenoming, such as tissue necrosis, renal failure, endocrinopathies, and serum sickness reactions from antivenin. … The rattlesnakes, moccasins, cottonmouths, and copperheads account for 95% of the annual snakebites in the United States.50 Spiders such as the black widow probably account for most of the neurotoxic syndromes that occur after spider bites.

The difference is important due to their lifestyles. is an indication for immediate treatment with antivenin effective against local neurotoxic species.

It has no effect on endplate sensitivity to acetylcholine, and blockade is not prevented by pretreatment with d-tubocurarine. In the case of vipers, coagulopathy is common and is usually first noted at the bite site, where unclotted blood drains from fang marks. Intramuscular and local injection of antivenin is not recommended. 22.35), which exhibit a diversity of color and banding patterns.

If bitten, the venom can cause death. However, it may bite if it's agitated. Important points regarding snake envenoming are highlighted in Table 48.9. We need to be careful with snakes.
