Disinfect the Bite Area
Rather than slicing the bite area or putting it under suction, you’ll want to simply avoid unnecessary contact with the wound with one exception.
You should clean the wound area after allowing it to bleed freely for 15-30 seconds.
Using an antiseptic wipe from a first aid kit, or simple soap and water, clean the bite area thoroughly to reduce the chances of infection. A snake bite is bad enough, the last thing you need is an infected one.
If you have a clean bandage, cover the wound loosely to protect it. If all you have is a dirty bandana, don’t bother.
If you can immobilize the bite area with a loose fitting splint, this can help minimize pain and inflammation.
All the while, monitor the bite victim for signs of shock (sweating, clammy skin, shallow breathing, etc.).
Do not apply ice or a cold pack to the bite area. Given the toxins and damage occurring around the wound, applying a cold pack to the area will most like reduce healthy circulation. It could even result in frostbite if apply for too long. Better to simply avoid these risks altogether.
