Outcome of trial of labor after cesarean section in women with past failed operative vaginal delivery

Objective The objective of this study is to determine the maternal and neonatal morbidity associated with attempting operative vaginal delivery (OVD) compared with the alternative of a laboring repeat cesarean delivery (LRCD) in women attempting a trial of labor after cesarean delivery (TOLAC). Methods This is a secondary analysis of a multicenter prospective study designed to assess perinatal outcomes of OVD in women with a prior uterine scar. The study includes women who attempted TOLAC and reached +2 station with a fully dilated cervix. Composites on neonatal and maternal morbidity were compared between women in whom OVD was attempted and those who underwent LRCD by fitting multivariate logistic regression models. Results In total, 6,489 women attempting TOLAC reached 2+ station with a fully dilated cervix. Of these, 5,640 (86.9%) had a spontaneous vaginal delivery, 762 (11.7%) underwent attempted OVD, and 87 (1.3%) had an LRCD. Compared with attempting OVD, LRCD was associated with greater neonatal morbidity (odds ratio [OR]: 2.41; 95% confidence interval [CI]: 1.13–5.15) and less maternal morbidity (OR: 0.28; 95% CI: 0.14–0.55). Maternal morbidity of OVD is driven by perineal injury. Conclusion In laboring women with a previous uterine scar, attempting OVD is associated with greater maternal and less neonatal morbidity than LRCD.

Objectives: To determine the frequency of successful Vaginal Birth after One Cesarean Section in our tertiary care institution and to determine the causes of its failure.Material and Methods: This study was conducted in department of Obstetrics and Gynecology of Shifa International Hospital and Shifa Foundation Community Health Centre Islamabad Pakistan from Feb 2011 to Dec 2014. This study included 592 patients who presented in labor room emergency reception of Obs/Gynae department at term with previous one scar having fulfilled the laid down inclusion criteria for VBAC during ante-natal care. The patients were admitted in hospital and were allowed to proceed for spontaneous labor under vigilant monitoring on complications of trial of scar. Immediate emergency cesarean sections were performed, where indicated.Results: Out of 592 patients 70.7% were delivered vaginally after previous one cesarean section and 29.3% had emergency cesarean section. Leading indications for repeat cesarean section was fetal distress, failure to progress and scar tenderness. No maternal and fetal complication occurred in our study. The success rate of Trial of labor after one previous cesarean delivery was lower in obese (64.38%) as compared to non-obese women (82.06%) (p<0.001). Women with previous successful vaginal delivery had a success rate of 88.2% compared with 62.25% in women without such a history (OR 4.4; 95% CI 2.7-7.2 p <0.001).Conclusion: Vaginal birth after one lower segment cesarean section should be encouraged with vigilant monitoring provided no obstetric contra-indication to vaginal birth exists.Bangladesh Journal of Medical Science Vol.15(4) 2016 p.546-550
