title: [Changes in blood coagulation time in patients bitten by young and adult Bothrops jararaca snakes].
abstract: Three hundred and forty eight cases of bites by adult Bothrops jararaca (group A) were admitted to the Hospital Vital Brazil between 1975 and 1984. These cases were compared to 623 cases of bites by young snakes of the same species (group B) during the same period and at the same hospital. There was no difference between groups regarding age or time between bite and admittance to the hospital. However in group B blood incoagulability was more frequent when compared to group A. We conclude that bites caused by young Bothrops jararaca are more likely to cause blood incoagulability in humans than bites caused by adult Bothrops jararaca.
