ABSTRACT
The objective of the study was to find out the factors predicting outcome of trial of labour after previous caesarean delivery among women living in a developing country. A retrospective study of 149 cases of trial of Labour was conducted in women with a history of one prior caesarean section. Binary logistic regression was used to identify predictive factors. The adjusted odds ratios with 95% confidence intervals (95%CI) were used to indicate risk of failure of the trial of Labour when the factor was present. It was found that success rate of vaginal birth was 24.16%. Factors significantly predictive of success of trial of Labour were previous vaginal delivery (OR 18.4, 3.3 -329.6), baby weight < 3 kg (OR 33.3, 5.4-62.6) and 2nd stage of labour during previous LSCS (OR 2.1, 1-4.2). The study has shown that trial of labour can be attempted successfully, in women with previous caesarean delivery, with due consideration of maternal and foetal outcome. A prior history of vaginal delivery and baby weight < 3 kgs are the best predictor of success of trial of labour.
