We have studied the number of important bleeds in our patients with respect to the age group in order to find criteria for putting the hemophilic child on an effective continuous prophylactic regime as early as possible. The bleeding sites are shown in the Tables. 48 children with severe hemophilia were studied. We observed an increase in bleeds with an increase in age. This increase in bleeds and their recurrence in preferential sites in a high percentage (48%) of these children indicate a higher exposure to trauma in part, and a gradual incipience of an arthro-miopathy as well. To avoid this occurring we propose beginning prophylactic treatment as early as possible.
