Afibrinogenemia following snake bite (Crotalus durissus terrificus).

Following the bite of Crotalus durissus terrificus, an 11-year-old boy developed afibrinogenemia and high output acute renal failure. His platelet count remained within normal limits. He was treated with epsilon aminocaproic acid and whole fresh blood transfusion, with full recovery from afibrinogenemia 40 hours after the beginning of these measures and 75 hours after the snake bite. No hemorrhagic disturbances were present. The acute renal failure was treated conservatively, and the patient recovered 12 days after the snake bite and discharged from hospital with no sequelae.
