When should Tranexamic Acid be considered?

• A. Chest or abdominal injury occurred more than 3 hours prior to proposed administration
• B. Blunt or penetrating chest or abdominal trauma with suspected blood loss
• C. Pediatric minor lacerations
• D. Non-hemorrhagic chest pain

Answer: (B)

Tranexamic acid is used in trauma to help reduce bleeding when there is an active hemorrhage, but timing matters. The best use is in a patient with blunt or penetrating trauma to the chest or abdomen who shows signs of blood loss, and it should be considered within the therapeutic window—within 3 hours of injury (ideally as early as possible). Giving TXA early can improve survival by stabilizing clots and limiting ongoing bleeding. It's not indicated for pediatric minor lacerations or for chest pain without signs of hemorrhage, since there isn’t significant bleeding to counteract. Also, administration after the 3-hour window offers diminishing benefit, so those scenarios are not appropriate for TXA.
