The problem, however, is that research strongly indicates that snakebite kits don’t work. One study published in the Annals of Emergency Medicine explains why. To put it into context, consider your last influenza vaccine shot … How easily do you really think that you could suction the medication from the muscle and fat in your arm once injected, especially one or more minutes afterwards? The practical answer is not easily.I'm sure it depends largely on depth of the bite, but even removing a small portion of venom could make a difference if you're far from a hospital.
Our local hospital doesn't stock anti-venin anyway. :/
So why would the same process work any better when a snake injects his venom into you?
In fact, additional research indicates that attempting to suction snake venom is likely more harmful to you than the initial bite because it could concentrate the hemotoxin thereby causing even more tissue damage.
So before you attempt to help a victim of snakebite, don’t just blindly rely on collective wisdom, what is shown on television, or what you spot on a store shelf. Instead, take a first-aid course, learn the facts, and continue to study.
