Objective: This study aims to explore the feasibility and safety of vaginal delivery for subsequent pregnancy in scarred uterus after cesarean section.

Methods: The observation group consisted of 62 puerperas who were admitted in our hospital and accepted vaginal trial delivery after subsequent pregnancy in scarred uterus from October 2015 to October 2016. The control group consisted of 60 primiparas who were hospitalized in the same period, satisfied the vaginal delivery conditions, and accepted vaginal trial delivery. Data of the two groups were statistically analyzed.

Results: Forty-nine puerperas in both groups underwent successful vaginal delivery with success rates of 79.03% and 81.67%, and their difference was not statistically significant (χ²=0.1339, P=0.7144). The duration of both the first stage and second stage of labor (364 ± 105 min and 54 ± 31 min, respectively) in the observation group was shorter than that in the control group, and the difference was statistically significant (P<0.05). Moreover, of the occurrence of postnatal complications was not different between the two groups (P>0.05).

Conclusion: Puerperas with scarred uterus could select vaginal delivery only if sufficient preparations are made before delivery and indications of vaginal delivery are strictly mastered.
