Abstract:
Introduction: Vaginal birth after caesarean (VBAC) is a vaginal child birth by a woman who has
had a surgical delivery caesarean section in the past.Multiple studies have shown that successful
VBAC has the lowest rate of maternal morbidity and mortality compared to elective repeat
caesarean delivery (ERCD).Vaginal delivery after previous one caesarean section for a nonrecurring indication has been described by several authors as safe and having a success rate of 60–
80%.
Objective:Toassess success rate of vaginal birth after caesarean section and factors associated with
VBAC in Women who gave birth atMettu Karl referral Hospital.
Method:Institutional based cross-sectional study was conducted at Mettu Karl referral Hospital
among 194 mothers who have one previous c\s scar. The data was collected by structured
questionnaire which pretested before data collection and participants were selected by sampling
convenienttechnique. The data was entered and cleaned by epidata 3.1 and analysed by SPSS v.20
to identify frequency distributions, mean with standard deviations and bivariate and multivariate
logistic regression was used to assess success rate of vaginal birth after caesarean section and
factors associated with VBAC. A95% confidence interval and 5% level of precision was used to
declare presence of association between dependent and independent variables in final model.
Results: The total number ofmother with one previous caesarean section who were offered trail of
labour and included in the study was 194 out of this 48(24.7%) was successful vaginal birth , the
independent variable history of meconium stained amniotic fluid [AOR=0.106(.023,.490)] pervious
history of VBAC [AOR=3.136(1.348,7.295)]andindication of pervious caesarean section with
unknown indication [AOR=.202(.057,718)]are highly associated with current VBAC.
Conclusion: Generally the overall success rate of VBAC is low inthis study when compared to
previous studies. The Study revealed that VBAC, previous historyofvaginal birth after C/Sscar,
previous indication of C/S Scar and Mecoinium Stained AmnioticFluidarethe main predictors of
Success rate of VBAC.
