title: Eclampsia: Maternal and neonatal outcomes.
abstract: The objective of our study is to define the maternal and neonatal outcomes associated with eclampsia. This retrospective cohort study was performed using the Consortium on Safe Labor, database from 12 clinical centers, including 19 hospitals, from 2002-2008. All patients admitted with a diagnosis of eclampsia or seizure in labor and delivery or postpartum were included in the analysis. Patients with history of seizure disorder were excluded. Maternal and neonatal outcomes were compared to outcomes of women with preeclampsia and their neonates. Statistical analyses were performed using SAS. Chi square and t-test were used for categorical and continuous variables, respectively. Logistic regression and general linear regression were used to calculate odds ratios and 95% confidence intervals. p<0.05 was considered significant. The eclampsia prevalence was 0.08% (n=191) in our population; the preeclampsia cohort had 7012 women. There were significantly more eclamptic women (49%) delivered by cesarean section, as compared to preeclamptic women (36%), OR 1.7 (1.28-2.28). These women were more likely to have an ICU admission OR 12.9 (7.0-23.7). The mean gestational ages and birthweights were lower in the neonates of the eclampsia group. A multivariate analysis revealed that low cord arterial pH, low 5min Apgar score, respiratory distress syndrome OR 5.5, (1.11-27.66) and seizures OR 10.3 (3.12-33.68), p<0.05, were significantly elevated in the eclampsia cohort. The prevalence of eclampsia in our contemporary obstetrics population was 0.08%. Both mothers as well as neonates of eclamptics are at significant risk for complications due to their illness.
