BackgroundTo evaluate the perinatal status of neonates delivered by assisted vaginal delivery (AVD) versus second-stage caesarean birth (CS).MethodsA 5-year retrospective study was conducted in a tertiary hospital. Data was analyzed with IBM SPSS (R) version 25.0 statistical software using descriptive/inferential statistics.ResultsA total of 559 births met the inclusion criteria; AVD (211; 37.7%) and second-stage CS (348; 62.3%). Over 80% of the women were aged 20-34years: 185 (87.7%) for the AVD group, and 301 (86.5%) for the second-stage CS group. More than half of the women were parous: 106 (50.2%) for the AVD group, and 184 (52.9%) for the second-stage CS group. The commonest indication for intervention in both groups is delayed second stage: 178 (84.4%) in the AVD group, and 239 (68.9%) in the second-stage CS group. There was a statistically significant difference in decision to delivery interval (DDI) between both groups: 197 (93.4%) women in the AVD group had DDI of less than 30min and 21 women (6.0%) in the CS group had a DDI of less than 30min (p< 0.001). During the DDI, there were 3 (1.4%) intra-uterine foetal deaths (IUFD) in the AVD and 19 (5.5%) in the CS group (p=0.023). After adjusting for co-variates, there were statistically significant differences between the AVD and CS groups in the foetal death during DDI (p=0.029) and perinatal deaths (p=0.040); but no statistically significant differences in severe perinatal outcomes (p=0.811), APGAR scores at 5th minutes (p=0.355), and admission into the NICU (p=0.946). After adjusting for co-variates, use of AVD was significantly associated with the level of experience of the care provider, with resident (junior) doctors less likely to opt for AVD than CS (aOR=0.45, 95% CI: 0.29-0.70).ConclusionSecond-stage CS when compared with AVD was not associated with improved perinatal outcomes. AVD is a practical option for reducing the rising Caesarean delivery rates without compromising the clinical status of the newborn.
