Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Given this background, the aim of this study was to compare the effect of early versus delay oxytocin infusion in achieving successful vaginal delivery among the low-risk nulliparous women in UKMMC. Besides, this study also compares the adverse maternal and neonatal outcomes between the two practices.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The randomisation sequence, either to the early oxytocin group or the delayed oxytocin group, was generated using the computer randomisation program in block of two. Allocation to either arm of treatment was determined by the sequential opening of sealed numbered envelopes.
In the first arm of early oxytocin group, labour augmentation with oxytocin was started early following artificial ruptured of membrane(ARM). In the second arm of delayed oxytocin group, oxytocin augmentation was delayed at two hours after ARM and this practice is currently being used as standard protocol in this hospital to manage women in labour. In both arms,the infusion rate was doubled every 30 minutes to a maximum of 48 mL/h or until four to five moderate contractions per 10 minutes were achieved at which point the infusion rate was maintained. Continuous fetal heart rate monitoring was maintained throughout the intrapartum period. Vaginal examination was performed at four hours after ARM as well as when clinically indicated ie. abnormal cardiotocography (CTG) and maternal desire to bear down. In the presence of abnormal CTG, either fetal blood sampling or expedited delivery was undertaken as per decided by the obstetrician in charge.
