During anesthesia, a sudden rise in peak airway pressures with hypotension most strongly suggests tension pneumothorax. What is the immediate management?

• A. High flow oxygen therapy alone
• B. Perform rapid decompression with needle thoracostomy at the 2nd intercostal space midclavicular line
• C. Place the patient in Trendelenburg position
• D. Increase positive end-expiratory pressure

Answer: (B)

When peak airway pressures suddenly rise and blood pressure falls during anesthesia, think tension pneumothorax because air builds up under pressure in the pleural space, collapsing the lung on that side and impeding venous return to the heart. The priority is to relieve that pressure immediately so ventilation and circulation can improve. The best immediate action is rapid decompression of the affected pleural space with a needle thoracostomy through the chest wall at the standard emergency site along the midclavicular line. This provides fast relief of the trapped air, allowing the lung to re-expand and venous return to recover. After decompression, proceed with placing a chest tube for definitive treatment and ongoing drainage. Supplemental oxygen is important but won’t resolve the critical mechanical problem quickly enough. Positioning the patient or increasing PEEP do not fix the underlying tension and can worsen the situation.
