Factors predictive of seizures and neurologic outcome in perinatal depression.
To identify which early clinical variables are predictive of outcome in newborns with perinatal depression, we prospectively examined newborns with persistently abnormal neurologic examinations at 48 hours and (1) arterial pH </= 7.15, (2) 5-minute Apgar </= 5, (3) requirement for positive pressure ventilation in the delivery room, or (4) fetal heart rate monitoring abnormalities. Eighty-four such infants completed neurodevelopmental assessment at 1 year. Five-minute Apgar (P = 0.0064), arterial pH (P = 0.0065) and base excess (P = 0.0003), neonatal encephalopathy grade at 48 hours and 7 days (both P = 0.0001), EEG at 48 hours and 7 days (both P = 0.0001), cranial ultrasound (US) at 48 hours (P = 0.0013) and 7 days (P = 0.0002), and the occurrence of neonatal seizures (P = 0.0001) all correlated significantly with developmental outcome, whereas fetal heart rate monitoring, mode of delivery, and presence of the non-neurologic hypoxic-ischemic encephalopathy syndrome did not. In the multivariate analysis, a combination of the 48-hour EEG and 48-hour cranial ultrasound provided the best model to predict developmental outcome, and a point system to predict developmental outcome based on these two variables is proposed.
