Postoperative chest-tube care centers on preventing new air or fluid from reaccumulating in the pleural space, helping the lung re-expand, and reducing infection risk, all while supporting patient comfort and safe healing. The action that is not a goal is increasing patient discomfort; the aim is to minimize pain and maximize safe lung expansion. Preventing recurrent pneumothorax or hemothorax is achieved by maintaining the pleural space under appropriate drainage and, when needed, suction to remove air or blood and allow re-expansion. Promoting lung re-expansion depends on a functioning, closed drainage system and regular assessment to ensure the lung fills the space as it should. Minimizing infection involves sterile technique, a closed system, proper dressing care, and monitoring for signs of infection. If pain becomes significant, the focus shifts to analgesia and addressing any tube-related issues, not to intensify discomfort.
