Maternal and neonatal outcome after vaginal breech delivery of nulliparous versus multiparous women of singletons at term—A prospective evaluation of the Frankfurt breech at term cohort (FRABAT)

Abstract

IntroductionThe best way to deliver a term breech infant is still a much discussed topic among obstetricians. The question whether nulliparity should be considered an exclusion criterion for an intended vaginal breech delivery is not fully answered. ObjectiveWe compared maternal and neonatal outcome of intended vaginal breech deliveries of nulliparous versus multiparous women at term. Study designWe conducted a prospective case-control study between January 2004 and December 2016. 1046 women expecting singletons at term with favorable pelvic measurements were enrolled in the study. ResultsNeonatal morbidity and mortality was not significantly different in deliveries of nulliparous (n = 647) versus multiparous (n = 399) women. Nulliparous women had a significantly higher rate of a cesarean section during labor than multiparous women. Maternal birth-injury rates and the use of epidural anesthesia were significantly higher comparing vaginal births of nulliparous (n = 384) versus multiparous (n = 331) women. ConclusionNulliparity seems not be an exclusion criterion for intended vaginal breech birth at term. It is still important to inform the women of an increased risk of a cesarean section during labor. A clinical management built on this evidence might reduce negative implications for future pregnancies.
