Severe cases of green pit viper snake venom poisoning

Two severe cases of green pit viper bites were reported. The clinical manifestations were severe bleeding and diarrhea. The first patient had acute renal failure complicated from severe diarrhea and hypovolemia. Hematological findings showed hypofibrinogenemia and thrombocytopenia. Renal biopsy performed in the first case showed a picture compatible with that of the recovery phase of acute tubular necrosis. Green pit viper antivenine serum together with symptomatic and supportive treatment was given. Both patients recovered uneventfully.
