Abstract

Background: Cesarean section is a procedure that is indicated when there are risks to the mother or fetus. The medical literature recommends considering the feasibility of vaginal birth after cesarean. (VBAC) Objective: Determine the prevalence and success factors in vaginal birth after cesarean. Hospital "Vicente Corral Moscoso" Cuenca, January-December 2019. Methodological design: Retrospective, analytical and cross-sectional study; sample of 314 medical records of women in the obstetric service. The success factors correspond to the Flamm score. The data were analyzed with the SPSS v.25 software; the results were presented in tables of frequencies and percentages. The association between VBAC and success factors was determined with Odds Ratios, 95% confidence interval and p-value less than 0.05. Results: The prevalence of VBAC was 24.5 x 100; the average age was 26.14 years, 75.3% live in urban areas, 40.3% in common law unions, 48.1% with a high school education level, and 68.8% are dedicated to household chores. Success factors corresponded to 83.4%, with previous vaginal delivery being significant for VBAC, different diagnosis in previous cesarean section, dilation greater than 4cm, effacement greater than 75%. The Flamm score of 3 was the most prevalent with 37.6%. Conclusions: One of four women with a previous cesarean section achieves a successful vaginal birth after cesarean. Previous vaginal delivery, a different diagnosis in a previous cesarean section, effacement and dilatation on admission are factors associated with the success of VBAC.
