Abstract
OBJECTIVE: To assess the risk of uterine rupture (UR) in attempted vaginal birth after cesarean and to identify risk factors. METHODS: Systematic review by consulting the following databases: PubMed (MEDLINE), Cochrane Library Plus, Embase, Nursing@Ovid, Cuidatge and Dialnet. The search was conducted between January and March 2015. MeSH descriptors used were: vaginal birth after cesarean; uterine rupture; labor induced and labor obstetric or trial of labor. There were no restrictions on date or language. The selection of articles was performed by 2 independent reviewers, standardized and unblinded. A critical review of the summary was conducted, and if was necessary, the full text was consulted. Prospective and retrospective documents were included. RESULTS: A total of 39 documents were included for their relevance and interest. Few clinical trials were found. The UR incidence on the results of the studies analyzed ranged from 0.15-0.98% in spontaneous labor; 0.3-1.5% in stimulation and induction with oxytocin, and 0.68-2.3% in prostaglandin inductions. CONCLUSIONS: The success of vaginal birth after cesarean is important and improves when conditions are optimal. However it is not without risks, the main one being UR. Induction of labor with oxytocin and/or prostaglandins appears as the main risk factor, while the spontaneous onset of labor and a prior vaginal birth are protective factors.
