Abstract

Introduction: Over the last decade, tranexamic acid (TXA) has been incorporated into treatment algorithms for a multitude of emergent conditions and the evidence surrounding its role in emergency medicine continues to evolve.

Objective: The objective of this literature review is to provide an evidence-based approach to the utilization of TXA in the emergency department.

Discussion: The most robust trials suggest TXA may offer a modest improvement in mortality in patients at risk of significant bleeding from trauma, but is not beneficial in spontaneous intracranial hemorrhage or gastrointestinal bleeding. The role of TXA in other clinical scenarios is less clear and requires clinical judgment.

Conclusion: Tranexamic acid appears to be a reasonable adjunct for the emergency medicine clinician to consider in the management of many hemorrhagic conditions and angiotensin converting enzyme inhibitor-induced angioedema. Additional high-quality research in these areas is needed to further identity patients who may benefit most from TXA.

Keywords: ACE inhibitor induced angioedema; Epistaxis; Hemorrhage; Postpartum hemorrhage; Tranexamic acid; Trauma.
