Which dressing approach is recommended for an open bubbling chest wound?

• A. Occlusive dressing over the wound taped on three sides
• B. Non-occlusive gauze dressing
• C. Suture the wound closed
• D. Remove dressings to visualize wound

Answer: (A)

Managing an open chest wound aims to prevent air from being sucked into the pleural space during inspiration while allowing trapped air to escape, reducing the risk of tension pneumothorax. Applying an occlusive dressing and securing it on three sides creates a flutter-valve effect: air can escape as the patient exhales, but air is less likely to be drawn in during inspiration. This seal helps stabilize the chest wall without trapping air inside. A non-occlusive gauze dressing wouldn’t seal the wound and would permit ongoing air entry, worsening the pneumothorax. Suturing the wound closed is a surgical intervention not appropriate in the field and could trap air or cause infection. Removing dressings to visualize the wound would remove a protective barrier and increase risk of contamination and air entry. Therefore, the three-sided occlusive dressing is the recommended approach.
