ObjectiveTo determine the incidence of moderate to severe neonatal encephalopathy (NE) and neonatal seizures without encephalopathy, and the association with metabolic acidemia. Secondly, to investigate the occurrence of suboptimal intrapartum care and its impact on neonatal outcome. DesignClinical audit. SettingTwo university hospitals in Sweden. PopulationNeonates 34weeks with moderate or severe NE and neonatal seizures alone, i.e. without encephalopathy, from a population of 71189 births, where umbilical blood gases were routinely analyzed. MethodsNeonates were categorized depending on the presence of metabolic acidemia at birth by umbilical artery pH<7.00, base deficit 12mmol/L. Records were audited for suboptimal care and a decision was made on whether management was assessed to have impacted neonatal outcome. Main outcome measuresEncephalopathy and seizures alone. ResultsWe identified 80 neonates with NE and 30 with seizures alone, of which 48 (60%) and none, respectively, had metabolic acidemia. Suboptimal care could be assessed in 77 and occurred in 28 (36%) NE cases and in one neonate with seizures alone (p<0.001). In 47 NE cases with metabolic acidemia, suboptimal care occurred in 22 (47%) vs. 6/30 (20%) without metabolic acidemia (p=0.02). Suboptimal care had an impact on outcome in 18/77 (23%) NE cases but in no cases with seizures alone. ConclusionSuboptimal care was commonly seen with NE, particularly in neonates with metabolic acidemia, and also affected neonatal outcome. No such associations were found in neonates with seizures alone.
