Podcast 828: TXA Dosing Update

Contributor: Nick Hatch, MD

Educational Pearls:

  • In the setting of traumatic injury, tranexamic acid (TXA) is given to stabilize clots which minimizes bleeding and decreases risk of hemorrhagic shock  
  • Current TXA dose for trauma is 1 g bolus followed by a 1 g infusion; both doses should be given within 3 hours from time of injury 
  • Due to the split dose and narrow window, patients with complicated care, particularly if they require transfer may miss the infusion dose 
  • Various smaller studies have shown that dosing 2 g initially or 2 g followed by a 1 g infusion produces the same patient outcomes and no additional harm 
  • Receiving hospitals should strive to acquire accurate information regarding previous doses of TXA given and confirm timeline of injury
