When is TXA indicated in prolonged casualty care?

• A. Early after injury when significant hemorrhage is suspected or present; administer promptly if protocol allows
• B. Never
• C. Only after 24 hours
• D. Only for non-hemorrhagic injuries

Answer: (A)

TXA helps reduce bleeding by blocking fibrinolysis, so its benefit comes from giving it as early as possible after injury when significant hemorrhage is suspected or present. In prolonged casualty care, the priority is to administer TXA promptly within the early window, ideally as soon as hemorrhage is suspected and a protocol allows, because delays lessen the benefit. It isn’t useful for non-hemorrhagic injuries and isn’t reserved for use only after 24 hours. Typical practice is a 1 g IV dose over 10 minutes, followed by 1 g over 8 hours if the protocol permits. Contraindications include known active intravascular clotting or hypersensitivity.
