RESUMO
Objective To investigate delivery mode of uterine scar pregnancy and analyze the safety of vagi-nal delivery.Methods 210 delivery women with scar uterus after cesarean section and 85 delivery women with non -scar uterus vaginal delivery of maternal selection were collected.According to the different ways of delivery,the preg-nant women in the scar group were divided into A group (72 cases)and B group (138 cases).Delivery outcome, maternal complications and average hospitalization time between the two groups were compared.Results 72 cases of maternal vaginal delivery in scar A group was successful and smooth vaginal delivery in 64 cases,and success rate was 88.89%(64 /72).8 patients maternal modified cesarean section production,accounted for 11.11%(8 /72),including 3 cases of persistent occiput posterior position,2 cases of social factors give up vaginal delivery,2 cases fetal distress, 1 case for incomplete rupture of uterus.138 cases delivery women in scar B group successfully obtained the cesarean section.100 cases of delivery women in non scar group,91 cases successfully got vaginal delivery,and the success rate was 91.00% (91 /100).Another 9 cases of delivery women were replaced with caesarean birth[9.00%(9 /100)],of which 3 cases of fetal distress,2 cases for fetal macrosomia,2 cases of persistent occiput transverse position,2 cases as social factors give up of vaginal delivery.Scar in group A maternal average hospitalization time was significantly shor-ter than scar in group B,and mean postpartum hemorrhage was significantly increased than scar in group B,and the differences were statistically significant (t =15.87,26.32,all P 0.05). The maternal average hospitalization time,mean postpartum hemorrhage,postpartum hemorrhage and incidence rate of neonatal asphyxia between scar group A and non scar group had no significant differences (χ2 =0.88,1.30,1.03, 0.00,all P >0.05).Conclusion When choosing vaginal delivery in scar uterus again pregnancy,we should strictly grasp cesarean section pregnancy after vaginal delivery of the indications.Under strict monitoring,the safety of vaginal delivery was high.It was worth of clinical promotion.
