Abstract：Objective To investigate the guiding value of intrapartum ultrasound in the delivery methods of primiparas with prolonged second stage of labor and its impact on maternal and neonatal outcomes.Methods A total of 100 primiparas with prolonged second stage of labor who delivered at Guangzhou Women and Children Medical Center from July 2022 to December 2023 were selected as the research subjects.They were randomly divided into a control group and an observation group,with 50 cases in each group.The control group was guided by simple vaginal digital examination,while the observation group received intrapartum ultrasound examination in addition to the control group's method.The delivery methods,maternal outcomes,and neonatal outcomes were compared between the two groups.Results The incidence of cesarean section,forceps-assisted delivery,and perineal lacerations of degrees III to IV in the observation group was lower than that in the control group,with a higher rate of spontaneous vaginal delivery,the amount of postpartum hemorrhage within 2 hours was significantly less in the observation group than that in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in neonatal birth weight between the two groups(P>0.05).The observation group had higher Apgar scores at 1 and 5 minutes after birth,and fewer neonates required respiratory support and admission to the Neonatal Intensive Care Unit(NICU),with statistically significant differences(P<0.05).Conclusion The guidance of delivery by combining vaginal digital examination with intrapartum ultrasound in primiparas with prolonged second stage of labor can reduce the rate of cesarean sections,decrease the amount of postpartum hemorrhage,improve the degree of perineal lacerations,and enhance neonatal outcomes.
