瘢痕子宫再次妊娠经阴道分娩可行性研究

The feasibility research on vaginal delivery of re-pregnancy in scarred uterus

目的探讨瘢痕子宫再次妊娠经阴道分娩的可行性及安全性。方法对2015年1～9月在我院住院分娩的瘢痕子宫产妇要求经阴道试产的80例作为研究组,并随机抽取同期非瘢痕子宫要求阴道分娩的80例作为对照组,进行回顾性分析。结果研究组中55例成功分娩,试产成功率达68.75%;对照组中57例成功分娩,试产成功率达71.25%。两组均未发生母婴死亡及子宫破裂等情况,且在产后出血量、新生儿窒息率、产褥感染率等比较,差异均无统计学意义（P〉0.05）。结论瘢痕子宫再次妊娠经阴道分娩是可行的,但应严密监护,把握好试产条件,较直接采取剖宫产,损伤小、恢复快。

Objective To investigate the feasibility and safety of vaginal delivery of re-pregnancy in scarred uterus.Methods A total of 80 patients of re-pregnancy with scarred uterus willing to vaginal delivery from January to September 2015 in our hospital were retrospectively analyzed as study group, another 80 patients with normal uterus were se lected randomly from inpatients during the same period as control group. Results 55 patients（68.75%） in study group and 57 patients（71.25%） in control group were successfully delivered. Rupture of uterus, death of maternal and infants were not occurred in both two groups. There was no significant difference between the two groups in achievement ratio,postpartum hemorrhage volume, neonatal asphyxia rate and puerperal infection rate（P〉0.05）. Conclusion Vaginal delivery of re-pregnancy in scarred uterus is feasible under exact evaluation and close monitor. It is superior with less trauma and quick recovery compared to cesarean delivery.
