First aid

Snakebite first aid recommendations vary, in part because different snakes have different types of venom. Some have little local effect, but life-threatening systemic effects, in which case containing the venom in the region of the bite by pressure immobilization is highly desirable. Other venoms instigate localized tissue damage around the bitten area, and immobilization may increase the severity of the damage in this area, but also reduce the total area affected; whether this trade-off is desirable remains a point of controversy.

Because snakes vary from one country to another, first aid methods also vary. As always, this article is not a legitimate substitute for professional medical advice. Readers are strongly advised to obtain guidelines from a reputable first aid organization in their own region, and to be wary of homegrown or anecdotal remedies.

However, most first aid guidelines agree on the following:

1. Protect the patient (and others, including yourself) from further bites. While identifying the species is desirable in certain regions, do not risk further bites or delay proper medical treatment by attempting to capture or kill the snake. If the snake has not already fled, carefully remove the victim from the immediate area. If possible, take a photograph of the snake (many cell phones are equipped with cameras). If you do not know what type of snake it is, someone else might be able to identify it from the photo. A poor photo is better than no photo.
2. Keep the victim calm. Acute stress reaction increases blood flow and endangers the patient. Keep people near the patient calm. Panic is infectious and compromises judgment.
3. Call for help to arrange for transport to the nearest hospital emergency room, where antivenin for snakes common to the area will often be available.
4. Make sure to keep the bitten limb in a functional position and below the victim's heart level so as to minimize blood returning to the heart and other organs of the body.
5. Do not give the patient anything to eat or drink. This is especially important with consumable alcohol, a known vasodilator which will speed up the absorption of venom. Do not administer stimulants or pain medications to the victim, unless specifically directed to do so by a physician.
6. Remove any items or clothing which may constrict the bitten limb if it swells (rings, bracelets, watches, footwear, etc.)
7. Keep the victim as still as possible.
8. Do not incise the bitten site.

Many organizations, including the American Medical Association and American Red Cross, recommend washing the bite with soap and water. However, do not attempt to clean the area with any type of chemical. Australian recommendations for snake bite treatment strongly recommend against cleaning the wound. Traces of venom left on the skin/bandages from the strike can be used in combination with a snake bite identification kit to identify the species of snake. This speeds determination of which antivenin to administer in the emergency room.
