Purpose
To compare the effect of combined oxytocin–misoprostol versus oxytocin and misoprostol alone in reducing blood loss at cesarean delivery.
Methods
One hundred fifty patients of 18–40 years with singleton term pregnancies scheduled for cesarean section under spinal anesthesia were recruited in a prospective double-blind randomized clinical trial to one of the three following groups to receive 20 IU infusion of oxytocin (group O), 400-µg sublingual misoprostol tablets (group M) or 200-µg misoprostol plus 5 IU bolus intravenous oxytocin (group MO) after delivery. The hemoglobin level before surgery and 24 h after surgery, the need for additional oxytocic therapy, and the incidence of adverse effects were recorded.
Results
The mean blood loss during surgery was significantly lower in group MO compared to other groups (P = 0.04). Comparison of mean arterial pressure (P = 0.38) and heart rate (P = 0.23) changes during spinal anesthesia and surgery failed to reveal any statistically significant differences between all groups through repeated measure analysis.
Conclusion
The use of combined lower dose of misoprostol–oxytocin significantly reduced the amount of blood loss during and after the lower segment cesarean section compared to higher dose of oxytocin and misoprostol alone, and its use was not associated with any serious side effects.
