Comparison of maternal and neonatal outcomes following TOLAC (Trial of labour after caesarean) vs. ERCS (Elective repeat caesarean section) in post-caesarean pregnancies: A prospective study

Abstract

Methods: A prospective study was carried out in the Department of Obstetrics and Gynecology at Government Thiruvannamalai medical college, Tamil Nadu from July 2019 to July 2020. 288 patients were included in the study who had previous one caesarean section. Out of this, 180 patients underwent elective caesarean section .108 cases fulfilled the TOLAC criteria and were given trial of labour. 62 patients had successful vaginal delivery. 46 had failed trial and underwent Emergency LSCS. Results: In this study VBAC success rate was 57.4%. Mode of delivery was significantly associated with history of one previous vaginal delivery. For neonatal outcomes, the difference was not statistically significant. Percentage of Elective repeat caesarean section (ERCS) was 62.5% (Group 2). Percentage of VBAC in TOLAC group was 57.4%(Group 1a). Percentage of Emergency caesarean section in TOLAC group was 42.6% (Group 1b). Conclusion: Prior vaginal delivery is a good predictor of VBAC. TOLAC is acceptable option for women with previous one caesarean section.
