• Breech presentation
• caesarean section
• external cephalic version

ObjectiveTo evaluate the success of an external cephalic version (ECV) training programme, and to determine the rates of successful ECV, complications, and caesarean birth in a low-risk population.
DesignProspective observational study.
SettingPrimary health care and hospital settings throughout the Netherlands (January2008-September2011).
PopulationLow-risk women with a singleton fetus in breech presentation, without contraindications to ECV, were offered ECV at approximately 36weeks of gestation.
MethodsData were collected for all ECVs performed by midwives, and were entered into a national online database.
Main measuresSuccessful ECV was defined as the fetus having a cephalic presentation immediately following the procedure and at birth. Complications were observed at 30minutes and between 30minutes and 48hours after the ECV procedure. All serious pregnancy outcomes that occurred after the ECV procedure until birth were reported.
ResultsA total of 47% had a successful ECv and a cephalic at the time of birth: 34% of nulliparous and 66% of multiparous women. After ECV, 57% of women gave birth vaginally: 45% of nulliparous women and 76% of multiparous women. Within 30minutes after ECV, and between 30minutes and 48hours after ECV, the proportion of women experiencing a complication or serious pregnancy outcome was 0.9% and 1.8%, respectively. Serious pregnancy outcome at any time following ECV until birth was experienced by 58 (2.5%) of the women.
ConclusionsThe success rate of ECVs performed by trained midwives in primary health care or hospital settings is comparable with that of other providers, and the procedure is safe for low-risk women.
