Amniotic fluid embolism-risk factors, maternal and neonatal outcomes

Objective. To investigate demographic characteristics, risk factors, maternal and neonatal outcomes of all cases of amniotic fluid embolism that occurred in New Jersey during 1997–2005.Methods. Information was derived from a perinatal linked dataset provided by the MCH-Epidemiology Program in the New Jersey Department of Health. Bivariate analysis for dichotomous variables used the Chi-square test. Stepwise logistic regression models were created to assess the influence of potential risk factors and p value < 0.05 considered statistically significant.Results. Forty-five cases of amniotic fluid embolism were identified among 1,004,116 deliveries, for a prevalence rate of 1 in 22,313 pregnancies. Statistically, significant association was found with multifetal pregnancy, caesarean section, placenta previa, placental abruption, eclampsia and cervical laceration. The rate of maternal complications such as coagulopathy, seizures, neurological damage, shock and cardiac arrest were significantly greater in the c...
