to assess the mode of childbirth and adverse neonatal outcomes in women with a breech presentation with or without an external cephalic version attempt, and to compare the mode of childbirth among women with successful ECV to women with a spontaneous cephalic presentation.
prospective matched cohort study.
25 clusters (hospitals and its referring midwifery practices) in the Netherlands. Data of the Netherlands perinatal registry for the matched cohort.
singleton pregnancies from January 2011 to August 2012 with a fetus in breech presentation and a childbirth from 36 weeks gestation onwards. Spontaneous cephalic presentations (selected from national registry 2009 and 2010) were matched in a 2:1 ratio to cephalic presentations after a successful version attempt. Matching criteria were maternal age, parity, gestational age at childbirth and fetal gender. Main outcomes were mode of childbirth and neonatal outcomes.
Measurements and findings
of 1613 women eligible for external cephalic version, 1169 (72.5%) received an ECV attempt. The overall caesarean childbirth rate was significantly lower compared to women who did not receive a version attempt (57% versus 87%; RR 0.66 (0.62–0.70)). Women with a cephalic presentation after ECV compared to women with a spontaneous cephalic presentation had a decreased risk for instrumental vaginal childbirth (RR 0.52 (95% CI 0.29–0.94)) and an increased risk of overall caesarean childbirth (RR 1.7 (95%CI 1.2–2.5)).
women who had a successful ECV are at increased risk for a caesarean childbirth but overall, ECV is an important tool to reduce the caesarean rate.
Implication for practice
ECV is an important tool to reduce the caesarean section rates.
