Blood-clot drug benefit
Immediate treatment with a cheap clot-stabilising drug could save the lives of thousands of people each year, including women with severe bleeding after childbirth, a study has found. A meta-analysis of more than 40,000 patients found that the likelihood of death due to blood loss was reduced by more than 70% if tranexamic acid was administered straight after injury or birth. But the effectiveness of the drug diminished over time. The chances of survival fell by 10% for each 15-minute delay, with no benefit seen when administered after three hours. Postpartum haemorrhage is the leading cause of maternal death worldwide, killing about 100,000 women a year.
