Milking chest tubes is generally contraindicated because it disrupts what?

• A. Infection control
• B. Pressure changes in the pleural space
• C. Flow rate
• D. Suction device function

Answer: (B)

Keeping the pleural space under stable negative pressure is essential for the lung to re-expand after chest tube placement. Milking or stripping the chest tube can cause abrupt changes in intrapleural pressure, which may push air or fluid through the system and create pressure spikes in the pleural space. These pressure fluctuations can lead to lung injury, re-expansion edema, or a new or worsened pneumothorax, so this maneuver is generally avoided. The concern centers on pressure dynamics in the pleural space, not primarily on infection control, flow rate, or the suction device itself. If drainage is not flowing properly, address the issue with appropriate clinical guidance rather than milking the tube.
