A chest tube, also known as a thoracostomy tube or chest drain, is a flexible tube that is inserted through the chest wall into the pleural space to remove air, fluid, or blood. The pleural space is the area between the lung and the chest wall. Chest tubes are commonly used in medical settings, particularly in emergency medicine, thoracic surgery, and critical care, to treat various conditions affecting the pleural space.
Here are key aspects of chest tubes:
-
Indications:
- Pneumothorax: To remove air from the pleural space.
- Pleural Effusion: To drain excess fluid (e.g., due to infection, cancer, or heart failure).
- Hemothorax: To remove blood from the pleural space (often due to trauma).
-
Insertion: A healthcare professional typically inserts a chest tube using a procedure called thoracostomy. The tube is placed through an incision in the chest wall.
-
Drainage System: The chest tube is connected to a drainage system (chest drainage unit or bottle) that allows air or fluid to exit the pleural space while preventing re-entry.
-
Water Seal: Many chest drainage systems include a water seal chamber, which acts as a one-way valve. It allows air to exit the pleural space but prevents atmospheric air from entering.
-
Suction Control: Some systems have a suction control chamber to apply controlled suction to the pleural space, aiding in the removal of air or fluid.
-
Monitoring: Healthcare professionals monitor the drainage system to assess the volume and characteristics of fluid or air being drained.
-
Removal: Once the underlying condition is resolved, the chest tube is removed. This is usually done under medical supervision.
Chest tubes play a crucial role in managing conditions that affect the pleural space, providing a means to drain unwanted substances and restore normal lung function. Their use requires proper medical training, and the decision to insert a chest tube is based on clinical evaluation and diagnostic findings.
