In trauma-related arrest, what should you do first?

• A. Start with rapid assessment and treat reversible causes, control hemorrhage, consider massive transfusion protocol; manage tamponade or tension pneumothorax if present
• B. Start with rapid imaging
• C. Delay intervention until imaging
• D. Focus only on chest compressions

Answer: (D)

The first thing to do in trauma-related arrest is start high-quality chest compressions right away to maintain perfusion of the heart and brain. In a life-threatening situation like this, every second without circulation worsens outcomes, so CPR should not be delayed for imaging or prolonged assessments.

As you begin compressions, you should rapidly identify and treat reversible causes and injuries that can be managed immediately—such as controlling hemorrhage, initiating massive transfusion if bleeding is significant, and addressing airway, breathing, and oxygenation. If signs point to tamponade or tension pneumothorax, treat those conditions promptly (for example, decompression or pericardial drainage as indicated) while continuing CPR.

The key idea is that maintaining circulation is the top priority and should be started right away; other important interventions are implemented concurrently and should not delay the start of chest compressions.
