Vaginal Birth after Cesarean Section (VBAC) Success Rate and Predictors of Success in a Tertiary Care Hospital
Objective: The objective of the study was to assess the success rate and safety of Vaginal Birth after Cesarean Section (VBAC) in the cases of previous Low Segment Cesarean Section (LSCS). The study also aims to understand and evaluate the predictors for successful VBAC.
Methods: A total of 160 cases of previous CS were enrolled in the study. Proper approval was approved from the ethical committee. Cases with previous classical or inverted T-shaped incision on the uterus, previous two or more LSCSs, with other uterine scars, history of previous rupture of the uterus or scar dehiscence, contracted pelvis or cephalopelvic disproportion, and those having other medical or obstetrical complications associated with pregnancy were excluded from the study. The trials for vaginal delivery were continued till there was satisfactory progress.
Results: 10% of the induced cases went for VBAC while 90% induced cases went for C-section. On the other hand, 58.8% of the spontaneous cases went for VBAC while 41.2% of the spontaneous women went for C-section. 62.8%booked patients were delivered via VBAC versus 13.6% of non-booked while 37.2% delivered via LSCS were booked versus 86.4% of non-booked.
Conclusion: Majority of the cases of previous CS done for nonrecurrent indication can be delivered safely by the vaginal route, without any major complication to the mother and the newborn, in an institution having facilities for emergency CSs. It has been proved to be a safe alternative to repeat an elective CS.
