Abstract:
Background. Operative vaginal deliveries (OVD) are vaginal deliveries accomplished with the use of a vacuum device or forceps. If
it is technically feasible and can be safely accomplished, termination of second stage labor by operative vaginal delivery is indicated
in any condition threatening the mother or fetus that is likely to be relieved by delivery. Hence, the objective of this study is to
assess the prevalence, common indication, outcome, and associated factors of operative vaginal delivery among mothers who gave
birth in Jimma University Medical Center (JUMC). Method. A facility-based cross-sectional study design was used in maternity
ward on 242 mothers who gave birth by operative vaginal delivery from December 01, 2016, to May 30, 2017. Te clinical data
were collected using a check list, recordings of intrapartum fetal and maternal state, and immediate fetomaternal outcomes. Te
study participants were recruited using consecutive sampling method. Sociodemographics and related data were collected at exit
using structured interviewer administered questionnaire which was developed by reviewing diferent literature and the remaining
information abstracted from patient charts. Data were entered to Epidata 3.1 and exported to SPSS version 21 for analysis. Bivariate
analysis was done to identify candidate variables using p<0.25. Multivariable logistic regression was used to control the efect of
confounding variables and to identify factors afecting the fetomaternal outcome. Statistical signifcance was declared at P<0.05
using adjusted OR with 95% CI. Result. Out of the 2348 pregnant mothers who gave birth in the labor ward of JUMC during the
6 months of the study period, 242 (10.3%) were by operative vaginal delivery (OVD). Te commonest indication for operative
vaginal delivery is found to be nonreassuring fetal heart rate pattern, 136 (56.2%). Out of all neonates delivered by operative vaginal
delivery 210 (86.8%) had favorable outcome. Of all mothers who gave birth by operative vaginal delivery 232 (95.9%) had favorable
outcome. Type of instrument used for operative vaginal delivery (AOR=0.228, 95%CI: 0.078, 0.671) and presence of grade two
(AOR=0.163, 95%CI: 0.031, 0.858) and grade three (AOR=0.088,95%CI: 0.024,0.327) meconium stained amniotic fuid are factors
afecting neonatal outcome while neonatal birth weight (AOR=0.007, 95%CI: 0.000, 0.151) is factor afecting maternal outcome of
operative vaginal delivery. Conclusion. Prevalence of operative vaginal delivery is found to be 10.3% with the commonest indication
of nonreassuring fetal heart rate pattern. Nearly all of mothers and neonates had favorable outcome. Type of instrument applied
for operative vaginal delivery is the strongest predictor of neonatal outcome while neonatal birth weight is the only predictor of
maternal outcome identifed in this study
