Abstract Background Trial of labor after a previous cesarean delivery (TOLAC) has helped to reduce the rate of cesarean section (CS). But the increased rate of adverse outcomes limites the spread of TOLAC. The most serious one is the risk of symptomatic uterine rupture, which is possibly associated with oxytocin. This meta-analysis was to evaluate the risk association between oxytocin use and uterine rupture in TOLAC. Methods Multiple electronic databases (PubMed, Embase, Web of Science, and Google Scholar) were searched for case-control or cross-sectional studies about TOLAC, oxytocin and uterine rupture, which were published between January 1986 and October 2019. The bias-corrected Hedge's g was calculated as the effect size using the random-effects model. The risk of bias was evaluated by the Newcastle-Ottawa Scale (NOS). Quality of the evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) certainty ratings system. Results There were 14 studies meeting inclusion criteria including 48457 women undergoing TOLAC. The pooled rate of VBAC and rate of uterine rupture in spontaneous labor were 74.3% and 0.7%. And the pooled rate of VBAC and rate of uterine rupture in induction labor were 60.7% and 2.2%. The women with spontaneous labor had significantly higher rate of VBAC (p=0.0032) and lower rate of uterine rupture (p=0.0003) than that with induction labor. The pooled rates of uterine rupture in women using oxytocin and women not using oxytocin in TOLAC were 1.4% and 0.5%. There was significant difference between these two groups (p=0.0002). Conclusions In TOLAC, women with induction labor had higher risk of uterine rupture than that with spontaneous labor. Oxytocin use may increase the risk. So simplified and standardized intrapartum management, precise procotol and cautiously monitoring of oxytocin in TOLAC are necessary.

Background: The objective of this study is to evaluate the outcomes of induction of labor in women attempting trial of labor after cesarean delivery and to compare maternal and neonatal morbidity and mortality in women who were induced to those delivering spontaneously.Methods: The prospective study was carried out in the Department of Obstetrics and Gynecology in collaboration with the Neonatal Section, Department of Pediatrics at J.N. Medical College and Hospital, AMU Aligarh. The sample included 280 women with one previous cesarean section, of whom 130 women underwent induction of labor (study group) and 150 were admitted with spontaneous onset of labor. Prostaglandin gel and intracervical Foley’s were used for cervical ripening in the study group. Indication of cesarean section, mode of delivery, maternal and neonatal outcome were studied in between groups.Results: Overall rate of vaginal delivery after cesarean section was 45.3% and 56% in both study and control group respectively. The rate of cesarean section were higher in women who were induced and having unfavorable cervix. Maternal and neonatal morbidity were not significantly higher as compared in both groups, however one case of scar rupture was found in study group.Conclusions: Induction of labor in women with previous cesarean section had higher rates of cesarean section however it does not adversely affect neonatal and maternal morbidity. Overall vaginal birth is safe and effective in women with previous cesarean section by prostaglandin gel or intracervical Foley’s. Authors cautiously suggest, induction of labor should be considered in preselected patient with strict monitoring.
