Misoprostol would reduce the uterine bleeding after caesarean delivery, without harmful effects on either mother or baby. The investigators postulated that the use of sublingual misoprostol during isoflurane anaesthesia for uncomplicated caesarean delivery would reduce maternal haemorrhage, uterine atonic effects, and the need for additional uterotonic agents, without harmful effects on either mother or baby. Therefore, the present study was designed to evaluate the effects of preoperative sublingual misoprostol on maternal blood loss, uterine tone, the need for additional oxytocin and neonatal outcome after elective caesarean delivery under isoflurane anaesthesia.
