Intracranial hemorrhage in the premature. Its predictive features and outcome.
Sixty-four infants with birth weights of 500 to 1,500 g were studied to determine the incidence and outcome of intracranial hemorrhage. Thirty-seven (58%) had hemorrhage and of these 60% died. Of the survivors, progressive hydrocephalus requiring treatment developed in only two infants. Serial computerized tomographic scans with measurement of ventricular-brain width ratios were found to be useful in objectively evaluating hydrocephalus. Review of perinatal data showed no association of maternal or obstetrical factors with neonatal hemorrhage but the infants who had intracranial bleeding showed a high incidence of low Apgar scores, respiratory distress syndrome, acidosis, hypoxia, apnea, hypotension, seizures, and requirement for respiratory support. Multiple regression analysis of potentially causative factors assigned importance to low gestational age, respiratory distress syndrome, birth asphyxia (low Apgar score), and vaginal delivery.
