| Popis: | Major hemorrhage remains a leading cause of death in both military and civilian trauma. We report the use of tranexamic acid (TXA) as part of a trauma exanguination/massive transfusion protocol in the management of hemorrhagic shock in a civilian primary and secondary air medical evacuation (AME) helicopter EMS program.TXA was introduced into our CCP flight paramedic program in June 2011. Indications for use include age16 years, major trauma (defined a priori based on mechanism of injury or findings on primary survey), and heart rate (HR)110 beats per minute (bpm) or systolic blood pressure (SBP)90 mmHg. Our protocol, which includes 24-hour online medical oversight, emphasizes rapid initiation of transport, permissive hypotension in select patients, early use of blood products (secondary AME only), and infusion of TXA while en route to a major trauma center.Over a 4-month period, our CCP flight crews used TXA a total of 13 times. Patients had an average HR of 111 bpm [95% CI 90.71-131.90], SBP of 91 mmHg [95% CI 64.48-118.60], and Glascow Coma Score of 7 [95% CI 4.65-9.96]. For primary AME, average response time was 33 minutes [95% CI 19.03-47.72], scene time 22 minutes [95% CI 20.23-24.27], and time to TXA administration 32 minutes [95% CI 25.76-38.99] from first patient contact. There were no reported complications with the administration of TXA in any patient.We report the successful integration of TXA into a primary and secondary AME program in the setting of major trauma with confirmed or suspected hemorrhagic shock. Further studies are needed to assess the effect of such a protocol in this patient population. |
