The choice of delivery mode of secondary pregnancy after cesarean section

Objective:To investigate the choice of delivery mode of secondary pregnancy after cesarean section.Methods:Six hundred and fourteen late pregnancy women with cesarean section were set as the observation group,and divided into group A(vaginal birth after cesarean section),group B(who could vaginal delivery,but choosing to cesarean section),group C(secondary cesarean delivery) and group D(third and fourth cesarean delivery).Three hundred and seventy-six late pregnancy women without cesarean section were set as the control group,and divided into group E(vaginal delivery) and group F(first cesarean delivery).The maternal and infant complications,operation time and hospital stay between group A and group B,between group A and group E,and between group C & group D and F group were analyzed.Results:The bleeding volume and time of hospitalization in group A after delivery were significantly less than that in group B(P<0.01).The differences of the rates of puerperal morbidity and neonatal asphyxia between group A and group B were not statistically significant(P>0.05).The differences of the postpartum bleeding volume,puerperal morbidity,time of hospitalization,neonatal asphyxia and rate of vaginal delivery between group A and group E were not statistically significant(P>0.05).The rate of perineal incision in group A was significantly higher than that in group E(P<0.01).The differences of the postpartum bleeding volume,puerperal morbidity,time of hospitalization and neonatal asphyxia between group C,group D and group E were not statistically significant(P>0.05).The operation time and abdominopelvic cavity adhesions rate in group F were significantly less than those in group C(P<0.01).The operation time and abdominopelvic cavity adhesions rate in group C and F were significantly less than those in group D(P<0.01).Conclusions:The vaginal trial production in the pregnant women with repregnance after cesarean section is safe according to the rigorous evaluation and selection,which can short hospitalization days and reduce maternal and infant complications.
