[Correspondence] Tranexamic acid for post-partum haemorrhage in the WOMAN trial
As one of the many collaborators who contributed to the WOMAN trial1 our team’s involvement in research that will improve maternal outcomes globally has been gratifying. 1 g of intravenous tranexamic acid given within 3 h of post-partum haemorrhage significantly reduced maternal death and the need for surgery (laparotomy). The fact that post-partum haemorrhage was defined as 500 mL or more for vaginal deliveries but 1000 mL or more for caesarean section is important to note. This difference should be considered when clinicians update local guidelines for post-partum haemorrhage.
