Obstetric Bleeding

Primary postpartum haemorrhage (PPH), is the leading cause of maternal death worldwide, responsible for around 100 000 deaths each year.

The WOMAN Trial evaluated the effect of tranexamic acid on death, hysterectomy and other surgical interventions and thromboembolic events in women with clinically diagnosed postpartum haemorrhage.   A total of 20,060 women with PPH were randomly allocated to receive tranexamic acid (1g intravenously) or matching placebo in addition to usual care. If bleeding continued, a second dose was given.

Death due to bleeding was significantly reduced with tranexamic acid (RR = 0·81, 95% CI 0·65–1·00, p=0·045), particularly in women treated within 3 hours of giving birth (RR =  0·69, 95% CI 0·52–0·91, p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] tranexamic acid vs 351 [3·5%] placebo; RR 1·02, 95% CI 0·88–1·07, p=0·84).

Treatment within three hours of delivery reduces deaths due to bleeding by about one third.
