Tranexamic acid
Circulation. It is more important to stem the flow of bleeding than to infuse fluids, and only casualties in shock or those who need intravenous (IV) medications should have IV access. Signs of shock include unconsciousness or altered mental status, and/or abnormal radial pulse. IV should be applied using an 18 gauge catheter and saline lock in tactical field care, secured by transparent would-dressing film. Tranexamic acid (TXA) should be given as soon as possible to casualties in or at risk of hemorrhagic shock. An intraosseous (IO) device could also be used for administering fluids if IV access is not feasible.
