Abstract
Tranexamic acid (TXA) is an antifibrinolytic that can prevent clot breakdown. Trauma patients often have coagulopathy which can cause mortality due to bleeding. The purpose of this review is to investigate the efficacy of TXA in reducing mortality in major trauma and secondly to look at patient's outcomes when using TXA in trauma.
Searches were performed in PUBMED, EMBASE and other databases for randomised controlled trials (RCT) and observational studies. The author searched for all relevant evidence on the use of TXA in major trauma. Relevant studies were assessed for quality using the Cochrane's Collaboration's tool for assessing risk of bias.
Eight relevant studies were identified from the search, 3 randomised controlled trials (RCTs) and 5 observational studies were identified. Five of the 8 studies found a significance in mortality with TXA use. Three showed TXA reduced mortality including the high quality level I evidence, CRASH 2 study. Three studies found no significance on mortality. There appears to be no increased risk of VOE with TXA however results from the studies varied. No study reported any adverse events due to TXA use. There does not appear to be any significant benefit of TXA use in TBI but a trend towards lower mortality. There is a role in paediatric trauma despite evidence from only 2 observational studies.
There is a high quality RCT to suggest the use of TXA in trauma patients with supporting evidence from observational studies. The outcomes in TBI are unclear. It may be beneficial in paediatric use but there is currently no level 1 evidence in paediatrics to support this. Further prospective studies looking specifically at role in TBI and paediatric trauma are required to support routine use in these specific populations.
