Flail chest management.

• A. Immediate surgical stabilization for all cases.
• B. High-dose steroids only.
• C. Adequate analgesia, chest physiotherapy, optimize ventilation; consider positive-pressure ventilation; surgical stabilization if needed.
• D. Observation only.

Answer: (C)

Flail chest is best managed by making the patient comfortable to breathe, keep the lungs well inflated, and clear secretions, while using ventilation support to stabilize the chest wall if needed. The key is to relieve pain and improve ventilation so the patient can take deep breaths and cough effectively, which reduces atelectasis and pneumonia risk. Adequate analgesia allows the patient to breathe deeply rather than pant or shallow-breathe, and chest physiotherapy helps mobilize and remove secretions. Optimizing ventilation supports gas exchange and reduces the work of breathing.

Positive-pressure ventilation can further stabilize the flail segment from the inside, improving oxygenation and decreasing paradoxical movement, thereby giving the injured chest wall a chance to heal and the patient to recover without exhausting the respiratory muscles. Surgical stabilization is considered only if conservative measures fail or if there is a severely unstable segment causing ongoing respiratory compromise.

Steroids are not a standard treatment for flail chest, and observation alone does not address the underlying respiratory mechanics and risk of hypoventilation.
