What dressing technique is recommended for chest-tube dressing changes after placement?

• A. Clean technique for dressing changes.
• B. Sterile technique for dressing changes.
• C. No dressing changes required after placement.
• D. Sterile technique only for ongoing care, not dressing changes.

Answer: (B)

Sterile technique is required for chest-tube dressing changes because placing a chest tube breaches the body's sterile barrier and creates a direct route for bacteria to reach the pleural space. Keeping the dressing change strictly sterile minimizes contamination, reducing the risk of local infection, empyema, or mediastinitis, and helps maintain a proper seal around the tube to prevent air leaks. In practice, this means performing hand hygiene, donning sterile gloves, using sterile supplies, maintaining a sterile field, and applying a sterile, occlusive dressing when re-covering the insertion site. Clean technique, while helpful for routine skin care, does not provide the level of asepsis needed for an invasive device, and assertions that dressing changes aren’t required or that sterile care is only for ongoing care miss the essential need to protect the insertion site from infection with every change.
