title: Timing of neonatal seizures and intrapartum obstetrical factors.
abstract: One hundred ninety-three neonates with seizures were available on a neonatal seizure database, which included intrapartum and neonatal factors such as labor duration, fetal heart rate abnormalities, cord blood gas values, Apgar scores and clinical signs of encephalopathy. Regression analyses (analysis of variance) were performed on the entire cohort as well as specific subsets of neonates (eg, neonatal encephalopathy vs no encephalopathy) to assess the relationship between seizure timing and intrapartum/neonatal factors. Seizures were noted earlier for the encephalopathic group than for the nonencephalopathic group. No significant differences were noted for any intrapartum or neonatal factors. Timing of neonatal seizures, with or without an encephalopathy occurs within the first 2 days after birth and is independent of selected intrapartum and neonatal factors, underscoring recent task force recommendations concerning neonatal encephalopathy. Factors other than intrapartum events more likely contribute to the encephalopathic repertoire of the newborn, including seizures.
