目的 探讨分析剖宫产后再阴道分娩(VBAC)试产结局的影响因素。方法 回顾性分析深圳市罗湖区妇幼保健院妇产科 2017年1月-2018年1月收拾的120例VBAC试产孕妇的临床资料，采用多因素logistic回归分析VBAC试产结局的影响 因素。结果 依据VBAC试产是否成功分为试产成功组和试产失败组，VBAC试产成功率为60.00%；两组在年龄、距离 上次剖宫产时间、是否具有阴道分娩史及宫口扩张程度等方面比较具有显著差异(P＜0.05)；logistic回归分析显 示，年龄、距离上次剖宫产时间、阴道分娩史及宫口扩张均是VBAC试产结局的影响因素。结论 年龄、距离上次剖 宫产时间、阴道分娩史及宫口扩张程度均是VBAC试产结局的重要影响因素，应做好产前检查，提高VBAC试产成功 率，改善母婴结局。

Objective To explore and analyze the influencing factors of trial production outcomes of vaginal birth after cesarean (VBAC). Methods The clinical data of 120 pregnant women with VBAC trial production who were treated in department of gynaecology and obstetrics of Luohu District Maternal and Child Health Hospital of Shenzhen City from January 2017 to January 2018 were retrospectively analyzed. Multivariate logistic regression analysis was used to analyze the influencing factors of VBAC trial production outcomes. Results According to whether the VBAC trial production was successful or not, the pregnant women were divided into trial production success group and trial production failure group, and the success rate of VBAC trial production was 60.00%. There were significant differences in the age, time away from last cesarean section, presence or absence of vaginal delivery history and cervical canal dilatation degree between the two groups(P<0.05). Logistic regression analysis showed that age, time away from last cesarean section, vaginal delivery history and cervical canal dilatation degree were the influencing factors of VBAC trial production. Conclusion Age, time away from last cesarean section, vaginal delivery history and cervical canal dilatation degree are important influencing factors of VBAC trial production outcomes. It is necessary to do prenatal examination so as to enhance the success rate of VBAC trial production and improve maternal-infant outcomes.
