title: Envenoming by the South American pit viper Bothrops neuwiedi Wagler.
abstract: Between 1975 and 1992, 18 cases of envenoming by Bothrops neuwiedi presented at the Hospital Vital Brazil, in São Paulo. Most of these cases were male (67%) and most had been bitten during the day (83%), between November and May (83%), either on the foot/ankle (50%) or hand (39%). Most (72%) of the cases arrived at the hospital 1-6 h after the bite. All presented with pain and most (83%) had oedema, but fewer had ecchymosis (50%), necrosis (17%), abscess (5%) and/or systemic blood-coagulation disorders (12%). Polyspecific Bothrops antivenom was administered to 16 (89%) of the patients. The results of B. neuwiedi bites therefore appear very similar to those of the much better known B. jararaca, even in terms of the gravity of the envenoming. Impairment in blood coagulation, however, seems less frequent among those bitten by B. neuwiedi than in those bitten by B. jararaca.
