Abstract To investigate the feasibility and safety of vaginal delivery of women with history scar uterus. Methods: From January 2016 to December 2017, 160 pregnant women with history cesarean were selected and divided into group A (the success of vaginal delivery group) and group B (the failure of vaginal delivery group). The incidences of postpartum hemorrhage, puerperal infection, and neonatal asphyxia of women in both groups were observed. Results: The successful rate of vagina delivery was 76.3%. The thickness of scar or the time from the last cesarean section of women in group A were significantly thicker or longer than that of women in group B, but the prenatal BMI of women in group A was significant lower than that of women in group B (P<0.05). The amount of vaginal bleeding in postpartum 24h of women in group A was significant less than that of women in group B (P<0.05). There were no significant different in rate of puerperal infection, fetal body mass, and postnatal 5 min Apgar score of newborns between the two groups (P>0.05). Logistic regression analysis showed that prenatal BMI (> 30kg/m2) and the time from the last cesarean section (≤2 years) were the influencing factors of vaginal delivery successfully. Conclusion: The vaginal delivery of pregnant women with history scar uterus is feasible without increase the risk of neonatal asphyxia, but the amount of postpartum hemorrhage maybe increase.
