Background: Labour occasionally may have need for induction or augmentation of labour and nulliparous women are at increased risk of dysfunctional labour. Oxytocin traditionally has been used for induction and augmentation of labour however prolonged labour continued to occur with attendant sequelae. Newer agents like propranolol, a beta blocker have been shown in few studies to decreases the duration of labour when used in synergy with oxytocin, though there is paucity of information and the only available systematic review was inconclusive. Hence, need for this study. Aim: The aim was to assess the role of oral Propranolol in short4ening the duration of labour during induction/augmentation with oxytocin. Methodology: This research was a clinical superiority open labelled randomized controlled trial that involved only nulliparous women who met the inclusion criteria and gave consent to the study over a 6month period. There was daily recruitment of participants. Participants were selected using simple random sampling by replacement and randomization was by utilizing computer-generated numbers from a pool of 110 participants divided into A and B. Group A received 20 mg of oral propranolol 10minutes before initiation of oxytocin titration. Group B received only oxytocin titration. Partograph was used to monitor their labour. Analysis: Absolute and relative frequencies of categorical variables, mean, range and standard deviation of continuous variables were calculated. Associations between continuous variables xvi were analyzed using students t-test while chi-square (χ2) test was used for categorical variables. A P-value of <0.05 was considered significant. Correction for hypothesis testing was done using Bonferroni correction test.
