Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] This embodiment provides a method for predicting vaginal delivery after cesarean section, such as figure 1 shown, including the following steps:

[0035] Step S1: collecting a large number of clinical data of pregnant women who were pregnant after cesarean section and had vaginal trial delivery;

[0036] Step S2: Comparative analysis of the clinical data of the two groups of pregnant and lying-in women in the clinical data, the measurement data of the univariate analysis is compared using t or t’ test, and the count data is compared using X 2 Statistically significant variables were included in the binary Logistic regression model for multivariate analysis, meaningless factors were eliminated, and independent factors affecting the success of vaginal trial delivery in pregnant women after cesarean section were screened out, and the influencing fa...

Abstract

The invention relates to a method for predicting re-pregnant vaginal birth after cesarean delivery. The method comprises the following steps: S1: collecting a large number of clinical data of pregnant and lying-in women experiencing re-pregnant trial vaginal birth after cesarean delivery; S2: comparing the clinical data of two groups of pregnant and lying-in women, screening independent influence factors for influencing successful re-pregnant trial vaginal birth after cesarean delivery, and calculating an odds ratio (OR) of each influence factor; S3: grading and classifying the independent influence factors, scoring the obtained odds ratios (OR) in combination with Logistic regression analysis so as to establish a predictive scoring table used before the re-pregnant vaginal birth after cesarean delivery; S4: according to the predictive scoring table, scoring the collected independent influence factors of each pregnant and lying-in woman, calculating a total score value, and drawing the total score values of all the pregnant and lying-in women into an ROC (receiver operating characteristic) curve to obtain an optimal critical score value, namely a cut-off point, wherein the cut-off point is a critical score value for judging whether a pregnant woman can accomplish the vaginal birth. By the method, a safe and feasible before-birth predictive scoring model for VBAC (vaginal birth after cesarean delivery) is established.

Description

technical field [0001] The invention relates to the medical and health field, in particular to a method for predicting vaginal delivery after cesarean section. Background technique [0002] According to a survey by the World Health Organization (WHO), the cesarean section rate in my country was as high as 46.2% between 2007 and 2008, and even exceeded 60% in many areas. China has become one of the countries with the highest cesarean section rate in the world. Cesarean delivery indicated by a history of cesarean delivery accounted for the top three causes. The United States and other countries have risen to the first reason. With the opening of the "universal two-child" policy, the problem of vaginal birth after cesarean section (VBAC) and the corresponding complications have become the focus of attention of the Chinese society and medical circles. [0003] In 1916, Cragin put forward the saying "one cesarean, another cesarean". In 1980, the above point of view was broken,...
