An affordable and broadly out there drug could save the lives of one in three mothers who would in any other case bleed to demise after childbirth, based on a serious research revealed in The Lancet.
The worldwide trial of 20,000 ladies discovered that demise as a result of bleeding was lowered by 31% if the treatment was given inside three hours.
The drug, referred to as tranexamic acid (TXA), works by stopping blood clots from breaking down. The findings additionally present it lowered the want for pressing surgical procedure to regulate bleeding (laparotomy) by greater than a 3rd (36%).
Severe bleeding after childbirth (often known as post-partum haemorrhage or PPH) is the main trigger of maternal demise worldwide. Greater than 100,000 ladies globally die annually from the situation, however this clot-stabilising drug has the potential to scale back the quantity considerably.
The WOMAN (World Maternal Antifibrinolytic) Trial recruited mothers from 193 hospitals in 21 international locations, primarily in Africa and Asia, but in addition in the UK and elsewhere. The London College of Hygiene & Tropical Drugs coordinated the trial. It was funded by The Wellcome Belief and UK Division of Well being by way of the Well being Innovation Problem Fund, and the Invoice & Melinda Gates Basis.

The outcomes present that of the ladies given tranexamic acid inside three hours, 89 died from bleeding in contrast with 127 given placebo (along with customary care). The researchers discovered no unwanted side effects from the drug for both mothers or infants. These findings present the first complete proof on utilizing tranexamic acid for post-partum haemorrhage and recommend it ought to be used as a frontline treatment.
Haleema Shakur, Affiliate Professor of Medical Trials at the London College of Hygiene & Tropical Drugs and Challenge Director on the WOMAN Trial, mentioned: “We now have essential proof that the early use of tranexamic acid can save ladies’s lives and guarantee extra youngsters develop up with a mom. It’s protected, inexpensive and simple to manage, and we hope that docs will use it as early as attainable following the onset of severe bleeding after childbirth.”
Tranexamic acid was invented in the 1960s by a Japanese husband and spouse analysis group, Shosuke and Utako Okamoto.
Ian Roberts, Professor of Medical Trials at the London College of Hygiene & Tropical Drugs, who co-led the research, mentioned: “The researchers who invented tranexamic acid greater than 50 years in the past hoped it will scale back deaths from post-partum haemorrhage, however they couldn’t persuade obstetricians at the time to conduct a trial. Now we lastly have these outcomes that we hope may help save ladies’s lives around the world.”
Nearly all of the deaths from post-partum haemorrhage are in low- and middle-income international locations. Though giving delivery in a well being facility will increase the likelihood of surviving post-partum haemorrhage, ladies nonetheless die from the situation even inside hospitals.
Tim Knott, Senior Accomplice in Improvements at Wellcome Belief, mentioned: “Globally, severe bleeding in childbirth stays one of the predominant causes of maternal demise – with alarming numbers of ladies dying in lots of low- and middle-income international locations. The WOMAN Trial group undertook a massively essential and extremely bold research. Their work stands to make a essential distinction in stopping ladies dying after childbirth.”
Whereas the WOMAN Trial discovered that tranexamic acid considerably lowered demise as a result of bleeding, it didn’t stop hysterectomy. The researchers say it is because in low- and middle-income international locations the place blood provides are restricted, a hysterectomy is usually carried out instantly after the onset of very severe post-partum haemorrhage to save the mom’s life. This implies there is no such thing as a time for tranexamic acid to have an impact.
The research builds on earlier analysis involving 20,000 trauma sufferers, which confirmed that tranexamic acid lowered deaths as a result of bleeding by nearly a 3rd if given inside three hours.
Present World Well being Group tips, based mostly on the earlier trauma analysis, suggest the use of tranexamic acid in post-partum haemorrhage as a subsequent treatment possibility if uterotonics (medicine to induce contractions) fail to regulate the bleeding, or if the bleeding is considered as a result of trauma.
Publish-partum haemorrhage is outlined as a blood loss of greater than 500ml inside 24 hours of giving delivery.
