Analysis of the clinical characteristics of forceps-assisted delivery based on intrapartum ultrasound assessment
摘要
Abstract
Objective To explore the characteristics of intrapartum ultrasound indicators in the initial stage of the second stage of labor in pregnant women with forceps-assisted delivery.Methods Base on a cohort of full-term singleton pregnant women who delivered in the maternity ward of Beijing Obstetrics and Gynecology Hospital,Capital Medical University,from March 2023 to August 2023.A retrospective,nested case-control study design was adopted,and 86 pregnant women who had forceps-assisted viginal delivery were included as research subjects(forceps delivery group).Another 172 pregnant women who had spontaneous vaginal delivery during the same period were randomly selected as the control group(natural delivery group)at a ratio of 1∶2.The differences in intrapartum clinical characteristics and intrapartum ultrasound indicators(fetal position,AOP,HPD)between the two groups were compared.The data were analyzed using t-tests,x2 tests,and bivariate correlation analysis.Results(1)Compared with the natural delivery group,the HPD[(32.44±10.04)mm vs.(27.42±7.89)mm],the time of second stage of labor[(79.00±52.30)min vs.(61.10±33.12)min],and the proportion of non-occipitoanterior fetal positions(20.93％vs.5.23％)in the forceps delivery group all significantly increased(P＜0.05),while the AOP[(138.25±14.50)° vs.(143.89±15.75)°]significantly decreased(P＜0.05).(2)There was a significant negative correlation between AOP and HPD,with the Pearson correlation coefficient r=-0.530(P＜0.01).AOP was positively correlated with the fetal presenting part(r=0.376,P＜0.01),and AOP=143.44°was equivalent to the fetal presenting part at S=+2;HPD was negatively correlated with the fetal presenting part(r=-0.485,P＜0.01)and positively correlated with the time of second stage of labor(r=0.132,P＜0.05),and HPD=28.39 mm was equivalent to the fetal presenting part at S=+2.Conclusion Intrapartum ultrasound indicators AOP and HPD can reflect the position of the fetal presenting,assisting in decision-making for forceps-assisted delivery and labor management.关键词
