About

Labour is usually physiologic, spontaneous and progressive, but occasionally, there may be the need for induction or augmentation of labour especially in nulliparous women, who 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, with minimal to no maternal and fetal adverse effects in labour have been shown to decreases the duration of labour when used in synergy with oxytocin. However, the paucity of information on the use of propranolol in labour.

Full description

ABSTRACT Background: Labour is usually physiologic, spontaneous and progressive, but occasionally, there may be the need for induction or augmentation of labour especially in nulliparous women, who 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, with minimal to no maternal and fetal adverse effects in labour have been shown to decreases the duration of labour when used in synergy with oxytocin. However, the paucity of information on the use of propranolol in labour.

Methodology: This research was a superiority open labelled randomized controlled trial that involved only nulliparous women who met the inclusion criteria and gave consent to the study. There was daily recruitment of participants. 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 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. Continuous variables 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.
