Quick Answer
A tourniquet should not be used for snake bites, as it can cause more harm than good by cutting off circulation and potentially leading to gangrene, and the venom still needs to be allowed to circulate for antivenom to be effective.
Tourniquet Use Contraindicated for Snake Bites
Do not use a tourniquet on a snake bite victim, as this can lead to unnecessary complications. The primary goal of first aid for snake bites is to keep the affected limb below heart level to slow down the spread of venom, remove any constricting items, and seek medical attention immediately.
Applying a Splint Instead
A splint may be applied to the affected limb to immobilize it and prevent further injury, but do not apply a tourniquet. Immobilize the limb by applying a splint or sling, and keep the patient calm and still to prevent further venom spread. Remove any constricting items such as watches, jewelry, or tight clothing.
Medical Attention and Antivenom
Once you have applied a splint, seek medical attention immediately. The medical professional will administer antivenom to counteract the snake venom, and the patient will need to be closely monitored for signs of envenoming, such as respiratory distress, cardiac issues, or renal failure.
