Surgical Bleeding

Every year there are over 300 million surgical procedures worldwide

Bleeding is an important complication and many patients require a blood transfusion

Research Overview

TXA for Surgical Bleeding

About one-third of transfused blood in the UK is used for surgical patients who receive an average of two units. 

However, blood for transfusion is a scarce and costly resource – most people in the world do not have access to donor blood, and blood transfusion is not without risk.

TXA has been used for many years in surgery and there is good evidence from randomised controlled trials that it reduces surgical bleeding.

A systematic review identified 129 trials including 10,488 patients. 

The results showed that TXA reduces the probability of receiving a blood transfusion by 38% (relative risk =0.62, 95% ci 0.58 to 0.65; p<0.001) and blood loss by 34% (proportional ratio=0.6695% CI 0.65 to 0.67; p<0.001).

These effects were seen across different surgical procedures and remained large when the analysis was restricted to trials with good allocation concealment.

TXA reduces blood loss in surgical patients by about one‐third. A total dose of 1 g appears to be sufficient for most adult surgical patients.

However, the effects of TXA on thromboembolic events and mortality in surgery are uncertain.

Although there were fewer deaths and myocardial infarctions in the TXA group, the pooled estimates were imprecise, and because many trials did not report data for these outcomes, there is the potential for bias due to selective reporting.

The uncertainty concerning the effect on thromboembolic events is an important factor limiting the uptake of TXA since an increase in thrombosis could outweigh the benefits of reduced blood use.

In trauma patients with significant bleeding and those with traumatic brain injury (TBI), TXA has been  shown to reduce mortality in both extracranial and intracranial bleeding

Postpartum Haemorrhage (PPH) is the leading cause of maternal death worldwide, responsible for around 100 000 deaths each year. TXA given as quickly as possible after birth and no later than 3 hours, reduces death due to bleeding and the need for surgery to stop bleeding

GI Bleeding is a common emergency that causes substantial mortality and morbidity worldwide. TXA was found to not reduce deaths from GI bleeding and showed an increased risk of thromboembolic events

Every year there are over 300 million surgical procedures worldwide. Bleeding is an important complication and many patients require a blood transfusion. TXA reduces blood loss in surgical patients by about one‐third. However, the effects of TXA on thromboembolic events and mortality in surgery are uncertain

There is ongoing research looking at how Tranexamic Acid (TXA) could be utilised for other bleeding conditions
