About

In order to reduce the cesarean sections rate, an adjunctive test is recommended in case of non-reassuring fetal heart rate tracing. In France, the reference adjunctive test is fetal scalp blood sampling. However, there is no study about the repetition of fetal blood sampling. Our hypothesis is that the repetition of fetal blood sampling is useful when fetal heart rate stays non-reassuring and may lead to vaginal delivery without impair neonatal prognostic. Therefore, our objective was to compare the patients with three or more fetal blood sampling with the patients with one or two.
