Perinatal features of birth asphyxia and neurologic outcome.
The perinatal events of 40 term newborn infants who had severe birth asphyxia were reviewed and correlated with the neurological outcome at a mean age of 2 1/2 years. Severe birth asphyxia was defined as an Apgar Score of less than or equal to 3 at 1 min. The majority (68.5%) of the babies had an abnormal fetal heart pattern before delivery. Persistent fetal bradycardia was most frequently associated with poor outcome. The neurological staging, the need for assisted ventilation for more than 24 hours and severe renal impairment were the best predictors of neonatal death or subsequent poor neurological outcome. The overall mortality was 10% and 15% of the surviving babies had varying degrees of neurological handicap.
