Abstract:【Abstract】 Objective To analyze the feasibility of repregnancy vaginal delivery of cesarean scar uterine.Methods 164 patients with repregnancy after cesarean section were divided into scar virginal group (n=52) and scar cesarean section group (n=112), according to the different modes of delivery. The postpartum indications, complications and neonatal conditions were compared between the two groups, and the scar cesarean section groupscar vaginal group was compared with 114 patients without scarred uterine and undergoing cesarean section for the first time (first cesarean section group) and 134 women undergoing vaginal delivery for the first time (first vaginal group).Results The postpartum 24h blood loss, incidence rates of postpartum fever, neonatal asphyxia and the length of hospital stay in the scar vaginal group were significantly lower than those in the scar cesarean section group (P<005). There were no significantly difference in puerperal disease rate, neonatal birth weight, newborn asphyxia rate and Apgar score between the two groups (P>005). Compared the cesarean section with previous cesarean section, there were significant differences in scarred uterine, fetal distress, fetal abnormalities, labor stagnation, threatened uterine rupture, pregnancy with internal medicine diseases and social factors surgical indications in the scar cesarean section group (P<005), while the other aspects showed none significant differences (P> 005), and the pregnancy outcomes also showed none significant differences (P>005). The postpartum 24h blood loss and length of hospital stay of scar cesarean section group were significantly more and longer than those of the first cesarean section group (P<005). There were no significantly difference in puerperal disease rate, neonatal birth weight, newborn asphyxia rate and Apgar score between the two groups (P>005). Conclusion Repregnancy vaginal delivery of scarred uterine can significantly reduce maternal and neonatal complications, shorten length of stay and has little effect on newborns. Under the condition of strict control of indications of vaginal delivery and close monitoring of labor conditions, vaginal delivery is recommended for women with scarred uterine and repregnancy.
