Success rate of vaginal birth after cesarean section in Kerbala maternity hospital

Abstract

Objectives To estimate the success rate of vaginal births after cesarean (VBAC) section and to identify its associated factors.
Methods A cross-sectional study of a retrospective data from Holly Karbala Maternity Hospital. In this study, 3000 case sheets were collected randomly during the period from October 2016 to August 2017. From those selected patients, 530 pregnant women with a prior lower transverse cesarean section were selected for the study. Patients with a singleton term pregnancy, vertex presentation, with no medical illnesses and opt to deliver by vaginal delivery were included. Patient’s information was analyzed regarding type of labor in relation to certain factors.
Results A total of 347 cases were included in the research. With a mean age and SD of 30.62 ± 5.98 years. Success rate for VBAC was 73%.The predicted probability of VBAC was significantly higher in those who had a previous successful trial of labor with a success rate of 78.5% than that who did not have previous vaginal delivery 56.1%. The success rate was significantly associated with older maternal age, increase parity and lower neonatal birth weight.
Conclusion The VBAC had high success rate, and the choice trial of labor after cesarean should be supported and chosen whenever it is possible over the choice of conducting second cesarean section. The success rate was positively associated with history of previous vaginal labor, older maternal age, higher parity and lower neonatal birth weight.
