TXA prevents clot breakdown by inhibiting fibrinolysis. Administered within 3 hours of injury, it reduces mortality in bleeding trauma patients. Later use may worsen outcomes. Diazepam, atropine, and dopamine have no role in primary hemorrhage control. TXA complements mechanical interventions (tourniquet, wound packing, pelvic binder) and resuscitation strategies (blood products, hypothermia prevention). Proper dosing, infusion protocols, and documentation ensure safety and effectiveness. TXA has become a cornerstone of modern tactical trauma pharmacology.

PACE (Primary, Alternate, Contingency, Emergency) ensures redundant communication. If primary radios fail, alternate nets, satellite comms, or runners provide backup. Reliable communication is critical for casualty reporting and synchronization with evacuation assets. It does not reduce CCP or HLZ requirements. A solid PACE plan ensures continuity even under degraded conditions, improving casualty outcomes.

Cushing’s triad—bradycardia, hypertension, irregular respirations—is a classic sign of rising intracranial pressure and impending herniation. It indicates urgent need for evacuation and temporizing measures: oxygenation, SBP ≥100–110, head elevation if tolerated, and brief controlled hyperventilation only if herniation suspected. Equal pupils and mild dizziness are not red flags. Recognition of Cushing’s triad under stress requires vigilance and triggers escalation to advanced care. Document changes, communicate via MIST, and expedite neurosurgical evacuation.

After correct binder placement over the greater trochanters, maintain it to decrease pelvic volume and tamponade venous bleeding. Gentle internal rotation of lower limbs with straps can further approximate the pelvis and reduce motion. Avoid removing the binder; displacement can re-open the pelvis and worsen hemorrhage. Diuretics are contraindicated; hypotension reflects blood loss, not fluid overload. Upright positioning may compromise hemodynamics and binder effectiveness. Continue balanced resuscitation, TXA per protocol, and hypothermia prevention. Limit logrolling and unnecessary manipulation; secure the casualty for transport with minimal jostling. Coordinate rapid evacuation to facilities capable of definitive hemorrhage control (preperitoneal packing, pelvic angioembolization, external fixation). Reassess distal pulses and skin integrity under the binder at appropriate intervals to prevent complications.

Massive hemorrhage kills fastest and is addressed first in the MARCH sequence. Tourniquets, hemostatic dressings, and pressure are immediate lifesaving interventions. Airway, respiration, circulation, and hypothermia follow. Adherence to MARCH ensures no critical step is overlooked under stress and reduces preventable battlefield deaths.
