ObjectiveTo compare the difference in risks of neonatal and maternal complications, including uterine rupture, in a second birth following a planned caesarean section versus emergency caesarean section in the first birth.DesignProspective cohort study.SettingPopulation-based cohort in the Netherlands.PopulationLinked data set of outcomes for term caesarean section in a first birth followed by a consecutive delivery.MethodsWe conducted a prospective cohort analysis using data from the Dutch Perinatal Registry. We included primiparous women who gave birth to term singleton infants through planned or emergency caesarean from January 2000 through December 2007, and who had a second singleton delivery during the same period (n = 41,109). Odds ratios and adjusted odds ratios were calculated.Main Outcome MeasuresMaternal and neonatal complications, specifically uterine rupture, in second births associated with planned and emergency caesareans in the first birth.ResultsWomen with a history of a planned caesarean section in the first birth (n = 11,445) had a 0.24% risk for uterine rupture, compared with a 0.16% risk for women with a history of emergency caesarean section (n = 29,664; aOR 1.4, 95% CI 0.8-2.4). In multivariate logistic regression, women with planned caesareans in a first birth had a significantly increased risk of stillbirth (aOR 1.5, 95% CI 1.0-2.2) and postpartum haemorrhage (aOR 1.1, 95% CI 1.0-1.2) in second births, compared with women with emergency caesareans in the first birth.ConclusionsWe found a moderately increased risk of postpartum haemorrhage and a small to moderately increased risk of uterine rupture and stillbirth as a long-term effect of prior planned caesarean delivery on second births.© 2013 Royal College of Obstetricians and Gynaecologists.
