In a patient with traumatic cardiac arrest due to blunt chest injury, what is the role of the AED?

• A. Apply the AED as you would in medical arrest.
• B. The AED is never used in any scenario.
• C. The AED is not indicated for traumatic cardiac arrest.
• D. The AED should be used only after paramedics arrive.

Answer: (C)

In traumatic cardiac arrest from blunt chest injury, the priority is to address reversible trauma causes and maintain perfusion, not to rely on defibrillation. The AED is not indicated because most traumatic arrests present with non-shockable rhythms (like asystole or pulseless electrical activity) resulting from severe blood loss, tamponade, or tension pneumothorax. Defibrillation only helps with shockable rhythms, so delivering a shock in this scenario is unlikely to restore a pulse and wastes valuable time that should be spent on high-quality CPR, hemorrhage control, airway management, and rapid transport. Therefore, the best approach is to proceed without relying on the AED and focus on treating the underlying injuries and supporting circulation.
