Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA randomized clinical trial comparing oral misoprostol with synthetic oxytocin or syntometrine in the third stage of labour.
This is a multicentre, blocked, randomized trial to compare the efficacy of oral misoprostol 400 microg with current injectable uterotonic agents (oxytocin/ Syntometrine) used prophylactically in the third stage of labour. Main outcome measures were blood loss, use of a second uterotonic agent and difference in haemoglobin level from antepartum to postpartum. ⋯ The use of a second uterotonic agent was higher in the misoprostol group (RR 2.89: 95% Cl 2.00-4.18) as well as a greater decrease in postpartum haemoglobin (p = 0.015). Oral misoprostol 400 microg is significantly less effective than the traditional intramuscular uterotonic agents currently used and therefore cannot be considered as a viable option to these agents in the management of the third stage of labour.
