产时超声对阴道分娩率及产后母婴不良结局的影响

Objective To explore the effect of intrapartum ultrasound application on improving the rate of vaginal delivery and reducing adverse postpartum outcomes for both mothers and infants. Methods A total of 200 pregnant women admitted to our hospital were selected between December 2022 and December 2024. They were randomly divided, using a random number table method, into a control group(n=100) and an observation group(n=100). The control group received traditional vaginal examination for labor management, while the observation group was managed with a new protocol that added intrapartum ultrasound. The delivery outcomes, incidence of fetal malposition, labor duration, angle of progression(AOP), headperineum distance(HPD), and adverse maternal and neonatal outcomes were compared between the two groups. Results The rate of natural delivery in the observation group was higher than that in the control group, and the incidence of abnormal fetal position was lower than that in the control group(P<0.05). The first and second stages of labor and the total stage of labor in the observation group were all shorter than those in the control group(P<0.05). There was no difference in the comparison of the latency AOP angle and HPD value between the two groups(P>0.05). The active phase and active phase/latent phase AOP angle and HPD value in the observation group were lower than those in the control group(P<0.05). The incidence of adverse maternal and infant outcomes in the observation group(9.00%) was lower than that in the control group(20.00%)(P<0.05). Conclusion The application of intrapartum ultrasound during delivery can significantly increase the rate of vaginal delivery, shorten the duration of labor, improve the early identification and successful correction of fetal malposition, and reduce the risk of adverse maternal and neonatal outcomes.
