Dall’Asta A, Rizzo G, Masturzo B, et al. - This study was undertaken to investigate the correlation between the transabdominal sonographic indices of fetal head flexion and the mode of delivery in women with protracted active phases of labor. Researchers enrolled a total of 129 women, of whom 43 had occiput posterior (OP) positions. They compared occiput-spine angle (OSA) and the chin-to-chest angle (CCA) between women who had vaginal delivery vs those who had a cesarean delivery. The data exhibited that the sonographic demonstration of fetal head deflexion in OP and in non-OP fetuses is correlated with an elevated incidence of cesarean delivery due to labor dystocia in women with protracted active phase of labor. Data imply that intrapartum ultrasound may contribute to the categorization of the etiology of labor dystocia.
