Abstract
Prehospital use of tranexamic acid (TXA) has grown substantially over the past decade despite contradictory evidence supporting its widespread use. Since the previous guidance document on the prehospital use of TXA for injured patients was published by the National Association of EMS Physicians, the American College of Surgeons Committee on Trauma, and the American College of Emergency Physicians in 2016, new research has investigated outcomes of patients who receive TXA in the prehospital setting. To provide updated evidence-based guidance on the use of intravenous TXA for injured patients in the emergency medical services (EMS) setting, we performed a structured literature review and developed the following recommendations supported by the evidence summarized in the accompanying resource document.The National Association of EMS Physicians, the American College of Surgeons Committee on Trauma, and the American College of Emergency Physicians recommends:• Prehospital TXA administration may reduce mortality in adult trauma patients with hemorrhagic shock when administered after lifesaving interventions.• Prehospital TXA administration appears safe, with low risk of thromboembolic events or seizure.• The ideal dose, rate, and route of prehospital administration of TXA for adult trauma patients with hemorrhagic shock has not been determined. Current evidence suggests EMS agencies may administer either a 1-g intravenous/intraosseous dose (followed by a hospital-based 1-g infusion over 8 hours) or a 2-g intravenous/intraosseous dose as an infusion or slow push.• Prehospital TXA administration, if used for adult trauma patients, should be given to those with clinical signs of hemorrhagic shock and no later than 3 hours post-injury. There is no evidence to date to suggest improved clinical outcomes from TXA initiation beyond this time or in those without clinically significant bleeding.• The role of prehospital TXA in pediatric trauma patients with clinical signs of hemorrhagic shock has not been studied, and standardized dosing has not been established. If used, it should be given within 3 hours of injury.• Prehospital TXA administration, if used, should be clearly communicated to receiving health care professionals to promote appropriate monitoring and to avoid duplicate administration(s).• A multidisciplinary team, led by EMS physicians, that includes EMS clinicians, emergency physicians, and trauma surgeons should be responsible for developing a quality improvement program to assess prehospital TXA administration for protocol compliance and identification of clinical complications.
