Randomized controlled trial assessing the benefit of cesarean wound drainage in pregnant women at increased risk of hemorrhage. The pregnant women at increased risk of hemorrhage were randomised in two groups. In one group 2 wound drainages were placed during the cesarean section, in the other group none. Outcome measures were difference between preoperative and postoperative hemoglobin, postoperative fever, cumulative opiate dose adjusted to body weight, length of stay and operation time. It is postulated that the pregnant women with increased risk of hemorrhage do not profit from the routine placement of wound drainages.
