Abstract:
Objective To establish a prenatal prediction scoring formula for evaluating the risk of vaginal trial delivery after cesarean section.The formula will guide the selection of delivery methods.Methods A total of 240 cases of vaginal trial delivery after cesarean section delivered in the Affiliated Women and Children's Hospital of Ningbo University from January 2019 to December 2020 were selected as subjects.According to the final mode of delivery,they were divided into two groups:successful group(n=202)and failed group(n=38).Single factor analysis and multivariate Logistic regression analysis were used to analyze the influencing factors of vaginal delivery after cesarean section.Based on these,prediction scoring formula was established.Results The success rate was 84.2％.The rate of uterine rupture was 0.99％.Overall prediction accuracy of the Logistic regression prediction formula was 83.8％,and fit degree of the formula was good(x2=8.828,P=0.357).The area under the curve was 0.798.Conclusion History of vaginal delivery,thickness of the lower segment of uterus and induced labor are independent influencing factors for vaginal delivery after cesarean section.The prediction scoring formula established by these three factors has good prediction efficiency and high accuracy.
