What should be done before removing a chest tube?

Before removing a chest tube, it's important to recognize that the proper technique involves ensuring that the patient does not experience unnecessary discomfort or complications during the procedure. Holding one's breath, specifically during the removal of a chest tube, assists in preventing the inhalation of air into the pleural space, which can lead to a condition known as a pneumothorax. By having the patient take a deep breath and hold it, intrathoracic pressure increases, which can help to seal the opening as the tube is withdrawn.

Although monitoring the patient's heart rate might be important for other procedures or general monitoring, it is not a specific action taken just before the removal of a chest tube. Similarly, administering a sedative may not be required unless the patient is particularly anxious, and applying antibiotic ointment is not standard practice for this procedure. Thus, the most appropriate action directly related to the technique of chest tube removal is having the patient hold their breath to minimize the risk of complications.
