What is considered the gold standard treatment for pneumothorax?

• A. Oxygen
• B. Small-bore catheter
• C. Chest tube attached to water seal
• D. Tube thoracostomy

Answer: (D)

The key idea is that the main goal in pneumothorax management is to remove air from the pleural space so the collapsed lung can re-expand. Giving oxygen speeds up the natural reabsorption of pleural air, but it does not adequately evacuate air to re-expand the lung in a significant or symptomatic pneumothorax. A small-bore catheter can be useful in some stable, smaller cases, but for a large or symptomatic pneumothorax, definitive management is necessary—draining the pleural space with a chest tube inserted into the chest (tube thoracostomy) and typically connected to a water-seal system, sometimes with suction. This setup provides continuous air removal and lung re-expansion, which is why it is the standard approach. The other options play supportive or selective roles: oxygen aids reabsorption, a small-bore catheter is an alternative in selected stable patients, but only the tube thoracostomy directly removes the intrapleural air needed for definitive treatment.
