What is the initial management for a suspected tension pneumothorax in trauma?

• A. Immediate needle thoracostomy followed by chest tube placement.
• B. Wait for imaging before acting.
• C. Use high-flow oxygen only.
• D. Listen to patient and observe.

Answer: (A)

In trauma with suspected tension pneumothorax, the priority is rapid decompression to relieve the pressure building in the pleural space, which collapses the lung and reduces venous return to the heart. This is an emergency where waiting for imaging can be fatal, so treatment must not be delayed. The initial step is immediate needle thoracostomy to quickly release trapped air and relieve the mediastinal shift, followed promptly by chest tube placement to allow continuous drainage and re-expansion of the lung. High-flow oxygen can support the patient, but it does not resolve the mechanical problem, and simply observing or delaying for imaging would miss the critical intervention.
