What type of dressing should be used after chest tube removal to prevent air entry?

• A. Loose gauze dressing.
• B. Non-occlusive adhesive bandage.
• C. Pressure dressing around the site.
• D. Air-tight occlusive dressing immediately after removal.

Answer: (D)

After chest tube removal, the wound tract is a potential entry point for air into the pleural space. Sealing it with an air-tight occlusive dressing creates a durable barrier that prevents atmospheric air from seeping in as the tract seals, reducing the risk of a recurrent pneumothorax. Loose gauze or a non-occlusive bandage won’t stop air from entering, and a dressing that isn’t airtight may fail to provide the necessary seal. Applying the airtight dressing promptly ensures the site is protected during the critical healing period, while ongoing monitoring for signs of pneumothorax remains important.
