If imaging after chest tube placement shows lack of lung re-expansion, what is the most appropriate next step?

• A. Ignore and wait for spontaneous improvement.
• B. Remove the chest tube immediately.
• C. Notify clinician and reassess for tube position, obstruction, or need for reinsertion.
• D. Increase suction to maximum.

Answer: (C)

When a chest tube doesn’t lead to lung re-expansion on imaging, the priority is to verify the tube’s position and patency and involve a clinician to decide the next steps. If the lung isn’t expanding, the problem is often related to the tube being malpositioned, or the tube being obstructed or kinked, which prevents drainage and sterner clearance of air or fluid from the pleural space. By notifying the clinician and reassessing the tube’s position, checking for clogging or obstruction in the drainage system, and considering the need for reinsertion if the tube is not effectively decompressing the space, you directly address the likely mechanical problems impeding expansion.

Ignore would delay or worsen the unresolved pneumothorax or effusion. Removing the chest tube immediately could deprive the patient of necessary drainage and worsen the underlying issue. Increasing suction to maximum may not fix a mechanical problem like malposition or obstruction and could risk tissue injury or other complications.
