Envenomation caused by poisonous animals

poisonous snakes

Abstract

Physiopathological, clinical and therapeutic aspects of human envenomation caused by Bothrops, Crotalus and Micrurus gender of poisonous snakes, prevalent in the southwest brazilian region, are discussed. The U.E.-HCFMRP-USP guidelines for treatment and the indications for antivenom serum are shown. If indicated, the antivenom serum should be given through intravenous infusion, drop by drop, after antihistaminic (anti H

1 and anti H2) and corticoids usage, to prevent possible hipersensibility reaction. No cutaneous sensibility test is advocated previously to the antivenom serum.
