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.

Abstract Uterine rupture is a serious public health concern that causes high maternal and perinatal morbidity and mortality in the developing world. Few of the studies conducted in Ethiopia show a high discrepancy in the prevalence of uterine rupture, which ranges between 1.6 and 16.7%. There also lacks a national study on this issue in Ethiopia. This systematic and meta-analysis, therefore, was conducted to assess the prevalence and determinants of uterine rupture in Ethiopia. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic review and meta-analysis of studies. All observational published studies were retrieved using relevant search terms in Google scholar, African Journals Online, CINHAL, HINARI, Science Direct, Cochrane Library, EMBASE and PubMed (Medline) databases. Newcastle–Ottawa assessment checklist for observational studies was used for critical appraisal of the included articles. The meta-analysis was done with STATA version 14 software. The I2 test statistics were used to assess heterogeneity among included studies, and publication bias was assessed using Begg's and Egger's tests. Odds ratio (OR) with a 95% confidence interval (CI) was presented using forest plots. A total of twelve studies were included in this study. The pooled prevalence of uterine rupture was 3.98% (95% CI 3.02, 4.95). The highest (7.82%) and lowest (1.53%) prevalence were identified in Amhara and Southern Nations, Nationality and Peoples Region (SNNPR), respectively. Determinants of uterine rupture were urban residence (OR = 0.15 (95% CI 0.09, 0.23)), primipara (OR = 0.12 (95% CI 0.06, 0.27)), previous cesarean section (OR = 3.23 (95% CI 2.12, 4.92)), obstructed labor(OR = 12.21 (95% CI 6.01, 24.82)), and partograph utilization (OR = 0.12 (95% CI 0.09, 0.17)). Almost one in twenty-five mothers had uterine rupture in Ethiopia. Urban residence, primiparity, previous cesarean section, obstructed labor and partograph utilization were significantly associated with uterine rupture. Therefore, intervention programs should address the identified factors to reduce the prevalence of uterine rupture.

Abstract Background Trial of labor after a previous cesarean delivery (TOLAC) has reduced the rate of cesarean sections. Nevertheless, the widespread use of TOLAC has been limited by an increase in adverse outcomes, the most serious one being the risk of symptomatic uterine rupture, which is possibly associated with oxytocin. In this meta-analysis, we explored the risk association between oxytocin use and uterine rupture in TOLAC. Methods Multiple electronic databases were searched for cross-sectional studies reporting on 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. A two-sample Z test was used to compare the differences in synthetic rates. The Newcastle-Ottawa Scale was used to evaluate the risk of bias.Results A total of 14 studies, which included 48457 women who underwent TOLAC, met the inclusion criteria. The pooled rate of vaginal birth after a cesarean section (VBAC) and the rate of uterine rupture in spontaneous labor were 74.3% and 0.7%, respectively. In addition, the pooled rate of VBAC and the rate of uterine rupture in the induction labor group was 60.7% and 2.2%, respectively. The women who had spontaneous labor had a significantly higher rate of VBAC (p=0.0032) and a lower rate of uterine rupture (p=0.0003) compared to induced labor. The pooled rates of uterine rupture in women using oxytocin and women not using oxytocin in TOLAC were 1.4% and 0.5%, respectively, and the difference was significant (p=0.0002). Also, the synthetic rate of uterine rupture in oxytocin augmentation among women with spontaneous labor and women who had a successful induction of labor were 1.7% and 2.2%, respectively, without significant difference (p=0.443). Conclusions Women with induced labor had a higher risk of uterine rupture compared to women with spontaneous labor following TOLAC. Oxytocin use may increase this risk, which could be influenced by the process of induction or individual cervix condition. Consequently, simplified and standardized intrapartum management, precise protocol, and cautious monitoring of oxytocin use in TOLAC are necessary.
