目的运用逐步判别分析方法建立剖宫产术后再次妊娠分娩(VBAC)结局函数,探讨其相关因素。方法采用回顾性研究方法,将172例VBAC产妇纳入分析,根据阴道试产结果分为阴道试产成功组96例和失败组76例,采集相关临床资料,分别用Fisher和Bayes逐步判别法构建试产结局方程。结果①保留在方程中的变量为年龄(X1),妊娠高血压疾病(X9),距前次剖宫产时间(X11)和子宫下段厚度(X12)。②Bayes判别方程:Y成功组=1.383X1+4.010X9-0.002X11+8.394X12-38.122;Y失败组=1.715X1+5.340X9-0.040X11+7.398X12-43.869;③回代法验证方程的敏感性和特异性分别是87.5%和85.5%。刀切法验证分别是83.3%和81.65%。结论年龄、妊娠高血压疾病、距前次剖宫产时间和子宫下段厚度与VBAC阴道试产结局显著相关;利用判别函数选择试产对象,并对符合试产条件的产妇给予充分试产机会是提高产科质量的关键。
Objective To establish the outcome function of VBAC after cesarean section using stepwise discriminant analysis to explore the related factors. Methods According to the results of vaginal trial, 96 cases of vaginal trial production and 76 cases of failure were included in the retrospective study. A total of 172 VBAC males were enrolled into the study. Relevant clinical data were collected and Fisher’s and Bayes step by step discriminant method Production outcome equation. Results ① The variables retained in the equation were age (X 1), pregnancy-induced hypertension (X 9), time from the previous cesarean section (X 11) and thickness of the lower uterine segment (X 12). ② Bayes discriminant equation: Y success group = 1.383X1 + 4.010X9-0.002X11 + 8.394X12-38.122; Y failure group = 1.715X1 + 5.340X9-0.040X11 + 7.398X12-43.869; ③ back to the law to verify the sensitivity of the equation and The specificity was 87.5% and 85.5% respectively. Knife-cut validation 83.3% and 81.65% respectively. Conclusions Age, pregnancy-induced hypertension (BPH) disease were significantly related to the previous CVAC vaginal delivery test results and the vaginal delivery test results. The discriminant function was used to select the test subjects and the full trial production opportunity Improve the quality of obstetrics the key.
