What does the acronym MARCH stand for in TCCC?

The acronym MARCH stands for Massive Hemorrhage, Airway, Respiration, Circulation, and Hypothermia. This systematic approach is fundamental in Tactical Combat Casualty Care (TCCC) and prioritizes the sequence of life-saving interventions needed in the field.

• Massive Hemorrhage: The first priority is to control any life-threatening bleeding, as traumatic hemorrhage is a leading cause of preventable death on the battlefield. Techniques such as applying a tourniquet or direct pressure are essential in this step.

• Airway: After addressing hemorrhage, ensuring the casualty's airway is clear and unobstructed is critical. This might involve maneuvers such as the recovery position or the use of adjuncts like nasopharyngeal airways if there are signs of airway obstruction.

• Respiration: Next, the focus shifts to breathing. Assessing for and managing tension pneumothorax is vital, as injury to the lungs or chest can impair oxygenation.

• Circulation: This step involves assessing the casualty's circulation and soft tissue injuries, ensuring that the heart is adequately pumping blood and monitoring for signs of shock.

• Hypothermia: Finally, the risk of
