My copy of Wilderness Medicine is at home, not the office so I don't have a good, "official" recommendation right now. IIRC, the best first aid is keeping the victim quiet, +/- on a snug, not tight band above the bite site (controversial), keeping the bite area cool(controversial) and transporting to the nearest hospital. Unfortunately, snake bites are a lot like appendicitis....there really isn't any first aid, only definitive care. <img src="/images/graemlins/frown.gif" alt="" />

A lot of bites are dry, and some only have minimal amounts of venom. Treatment with antivenom and supportive care is an ongoing clinical decision based on how a patient is doing.
