详细描述
Intrapartum ultrasound monitoring is to be compared with conventional labor monitoring to clarify the accuracy of this technology, and then provide a basis for later related research. All pregnant women intending to have a vaginal delivery were enrolled in the study. After admission, women were randomly assigned to either intrapartum ultrasound (IPUS) or vaginal examination (VE). In IPUS group, the patient was evaluated by ultrasound, including fetal orientation, pelvic and cervical conditions. IPUS and VE were performed every 2 to 4 hours during the first stage of labor and at least hourly during the second stage. The progress of labor, the occurrence of complications and the prediction of the success rate of vaginal delivery were observed. Finally, the investigators compared whether there were any differences in labor and vaginal delivery complications between the two groups.
