【摘要】：目的:分析剖宫产术后阴道分娩(VBAC)的影响因素。方法:选取剖宫产术后阴道试产(TOLAC)的114例孕妇。超声测定其宫颈长度,根据最终是否成功VBAC分为成功组和失败组,采用单因素和多因素Logistic回归分析影响VBAC的因素,观察宫颈长度是否是影响VBAC的独立因素。结果:TOLAC成功率为46.49%。单因素分析显示,成功组和失败者的年龄、出血量、孕产次、距上次剖宫产时间、上次是否进入产程、分娩孕周、阴道分娩史等比较,差异均无统计学意义(均P0.05);成功组的自然临产率和分娩镇痛率均较失败组高(均P0.05),新生儿体重低于失败组(P0.05)。Logistics多因素分析显示,自然临产和宫颈长度为VBAC的独立影响因素,自然临产(B=3.014,P0.001,OR=20.372)为TOLAC成功的保护因素,宫颈长度为TOLAC成功的危险因素(B=-0.091,P0.05,OR=0.913)。成功组的平均宫颈长度(19.86±11.05)mm,明显短于失败组[(28.61±7.75)mm](P0.01)。宫颈长度每减少1mm对TOLAC成功的优势比为1.095。结论:自然临产是TOLAC成功的有利因素,超声测量的宫颈长度为TOLAC成功率的独立影响因素。
[Abstract]:Objective: to analyze the influencing factors of vaginal delivery (VBAC) after cesarean section. Methods: 114 pregnant women with vaginal trial labor after cesarean section were selected and their cervical length was measured by ultrasound. According to the final success of VBAC was divided into success group and failure group. Univariate and multivariate Logistic regression analysis was used to analyze the influencing factors of VBAC. Results the success rate of VBAC was 46.49%. Univariate analysis showed that the age, blood loss and pregnancy rate of the successful group and the loser were the same. There was no significant difference between the last time of cesarean section, whether or not to enter the labor process, the gestational week of delivery, the history of vaginal delivery, and so on (all P 0.05). The natural labor rate and labor analgesia rate in the successful group were higher than those in the failed group (all P0.05%), and the weight of the newborn was lower than that in the failed group (P0.05N. Logistics multivariate analysis showed. Spontaneous labor and cervix length were independent factors of VBAC, and the natural parturition Bu 3.014 P 0.001 ORG 20.372) was the protective factor of TOLAC. The length of cervix was a risk factor for success of TOLAC. The average cervical length in the successful group was 19.86 卤11.05 mm. Significantly shorter than failure group. [(P 0.01). The odds ratio of cervix length reduction 1 mm to success of TOLAC was 1.095. Conclusion: spontaneous labor is a favorable factor for success of TOLAC. The length of cervix measured by ultrasound was an independent factor influencing the success rate of TOLAC.
