The value of ultrasound measurement of labor process progression parameters in predicting delivery outcomes
Objective To explore the value of ultrasound measurement of labor progression parameters in predicting delivery outcomes.Methods 94 vaginal trial delivery women were selected as the study subjects and divided into two groups based on delivery outcomes.77 successful vaginal deliveries were selected as the success group,and 17 failed trial deliveries transitioning to cesarean section were selected as the control group.Both groups underwent ultrasound monitoring of fetal head progression angle(AOP)and fetal head perineal distance(HPD)at 6 cm and 1～2 hours after the opening of the cervix.The levels of AOP and HPD were compared between the two groups,and the predictive value of AOP and HPD for delivery outcomes was analyzed using receiver operating characteristic(ROC)curves.Results At the opening of the cervix to 6 cm and 1-2 hours later,the AOP of the successful group was higher than that of the control group,and the HPD was shorter than that of the control group(P＜0.05);The application of ROC curve analysis showed that AOP and HPD have good value in predicting delivery outcomes(P＜0.05).Conclusion Ultrasound monitoring of AOP and HPD at 6 cm and 1～2 hours after the opening of the cervix has high value in predicting the delivery outcome of parturients,and can provide scientific basis for delivery management.
