Venom of the Common Lancehead, Bothrops atrox, was injected subcutaneously into rats in a series of increasing doses. Half of each dose group then was shocked with a device used by the Ecuadoran group. Envenomated animals developed hemorrhagic ulcers at the injection sites, the size of which was strongly related to venom dose. Electric shock did not influence the development of morbidity or the eventual ulcer size in sublethally envenomated animals, nor did shocks reduce mortality in lethally envenomated animals. We conclude that shocks are without effect on snakebitten rats, and we discuss implications of our findings for the treatment of snakebitten human beings.
Electric shocks are ineffective in treatment of lethal effects of rattlesnake envenomation in mice.
Oklahoma State University, Stillwater 74078. Electrical shocks, even crudely delivered from 'stun guns' and gasoline engine spark plugs, have been reported to be effective in the treatment of snake bite. We thus applied similar electric shocks to mice artificially injected with reconstituted rattlesnake venom at various LD50 multiples. Those envenomated mice treated with electric shock survived no better than the controls. We thus found no evidence that electric shocks crudely administered had any life saving effect in mice.
