In an effort to shorten hospital stay and to further decrease mortality, a new antivenom has been developed. This antivenom is a third generation F(ab')2 "fabotherapeutic" agent.It is administered intravenously which should lead to rapid neutralization of circulating venom. This study will demonstrate whether or not use of the new antivenom in children receiving standardized supportive care leads to resolution of the syndrome within 4 hours of treatment.The onset of clinical symptoms following a scorpion envenomation is usually within 5 to 30 minutes following the sting.
