Abstract:

Objectives: The main objective of this study was to observe the values of transperineal ultrasound parameters in labour both in occiput anterior and occiput posterior (OP) position, and also to verify their importance in labour management. Methods: 91 patients in labour were included in this study, with gestational age over 37 weeks and estimated fetal weight over 2500 g, singleton pregnancy, cephalic presentation, empty urinary bladder. For these patients several ultrasound parameters were assessed: angle of progression, distance of progression, head direction, fetal head rotation, and fetal head-perineum distance. Results: 36 of 91 patients included in the study had an occiput posterior (OP) position     (39.56%) at the first ultrasound exam. 5 patients (5.49%) presented persistent OP position, all of them primiparous. 85 patients (93.4%) had vaginal delivery, 6 patients requiring cesarean section, 5 of which were patients that presented persistent OP position and lack of progress in labour. Ultrasound parameters were measured at the beginning of labour and they showed favorable values in all 5 cases with persistent occiput posterior position. However, in the second stage of labour, values maintained favorable in only one case. Conclusions: The vast majority of OP position had vaginal delivery in occiput anterior position. Similarly, the large majority of cesarean cases presented persistent OP position, with favorable ultrasound parameters values in the first stage of labour, and one case maintaining favorable values in the second stage of labour. Patients with occiput anterior position presented favorable parameters values throughout the labour
