Sponsor's own description
Ultrasound during labor and measurement of Angle of progression showed extensive prospective and retrospective publications since 2010. The investigators performed between 2013 and 2016 the only one multicenter, randomized controlled Trial comparing digital exam to angle of progression after a prolonged 2-hour second stage of labor with uncertain fetal head. The investigators consider a cut off of 120° to accepted vaginal birth among cephalic occiput anterior position This randomised PILOT study showed that measurement of Angle of progression in addition to digital exam reduced caesarean delivery from 41% to12% ( n= 33, p=0,06). doi: 10.1016/j.ajog.2022.04.018. The objective of this new study is therefore to validate the results of this PILOT study in a more powerful multicenter randomized trial (DELIVERY).
