Oral misoprostol for the third stage of labor: a randomized controlled trial.
OBJECTIVE
To compare oral misoprostol with conventional oxytocics in the management of the third stage of labor. In a controlled trial, 1574 women were randomized into four groups, as follows: Group 1 received intravenous infusion of oxytocin 10 IU plus oral misoprostol 400 micro g, followed by two doses of oral misoprostol 100 micro g 4 hours apart; group 2 received oral misoprostol 400 micro g, followed by two doses of oral misoprostol 100 micro g 4 hours apart; group 3 received intravenous infusion of oxytocin 10 IU; and group 4 received intravenous infusion of oxytocin 10 IU plus intramuscular administration of methylergonovine maleate (Methergine) 0.2 mg. The incidence of postpartum hemorrhage and decrease in hemoglobin concentration from before delivery to 24 hours postpartum were the main outcome measures.


RESULTS
The primary outcome measures were similar in groups 2 and 3. The incidence of postpartum hemorrhage was 9% in group 2, compared with 3.2% in group 1 and 3.5% in group 4 (P <.01, and P =.01, respectively). There were no significant differences among the four groups regarding hemoglobin concentrations. Significantly more women needed additional oxytocin in group 2, when compared with group 4 (5.9% versus 2.2%; P =.01). The proportion of women requiring additional methylergonovine maleate was 4.8% in group 2, compared with 0.7% in group 1 and 1% in group 4 (P <.01 and P =.01, respectively).


CONCLUSIONS
Oral misoprostol alone is as effective as oxytocin alone for the prevention of postpartum hemorrhage; it is less effective than oxytocin plus methylergonovine maleate and oral misoprostol plus oxytocin.
