[Role of misoprostol in the delivery outcome].
OBJECTIVE
Delivery-induced hemorrhage is defined as a blood loss greater than 500 ml within the first 24 hours after delivery. Loss of more than 1000 ml is a sign of gravity. For certain authors, 40% of these hemorrhages could be avoided with systematic preventive measures using uterotonic agents to control the third phase of labor. The aim of our work was to assess the preventive efficacy of active management measures during the third phase of labor and to determine which agents are most effective.


METHODS
We compared two protocols for controlled deliver: a conventional method using ocytocin (2.5 IU i.v. bolus), and a more recent method using a prostaglandin E1 analog: misoprostol (Cytotec, 3 tablets per os). We compared the two methods with a control group where no preventive measures were used, the standard procedure in our maternity unit.


RESULTS
Six hundred two women participated in the study. They were divided into 3 homogeneous groups (ocytocin group misoprostol group, control group). There was a 46% reduction in delivery-induced hemorrhage in the ocytocin group but only a minimal preventive effect against severe hemorrhage. Misoprostol did not demonstrate any efficacy in our study.


CONCLUSIONS
It would appear appropriate to take preventive measures against delivery-induced hemorrhage for all deliveries. A bolus intravenous injection of ocytocin immediately after delivery should bed used. The dose should be greater than that used in this study in order to prevent the development of severe hemorrhage. The most satisfactory results can be obtained with 5 IU (1 ampoule of Syntocinon). It is important to obtain a precise quantification of excessive blood loss in order to institute appropriate care rapidly. Misoprostol should be assessed with other prospective studies because of its easy administration, its low cost and easy storage, important advantages in countries with limited resources.
