-
Pneumothorax
- Tension pneumothorax, after immediate needle decompression
- Large or symptomatic pneumothorax
- Pneumothorax causing respiratory compromise
- Persistent air leak
- Recurrent pneumothorax after needle aspiration
- Traumatic pneumothorax, especially if the patient may need positive-pressure ventilation
-
Hemothorax
- Traumatic hemothorax
- Significant postoperative or spontaneous hemothorax
- Hemopneumothorax
-
Pleural infection
- Empyema thoracis
- Complicated parapneumonic effusion, especially if pus is present, Gram stain/culture is positive, pH is low, or the collection is loculated
-
Large or recurrent pleural effusion
- Symptomatic effusion causing dyspnea or lung compression when repeated aspiration is unsuitable
- Malignant pleural effusion requiring drainage before pleurodesis
- Chylothorax, depending on volume and clinical setting
-
Chest trauma / postoperative drainage
- Following thoracotomy, lung resection, or some cardiac/thoracic operations
- Following penetrating or blunt chest trauma with pleural collection
-
Selected procedural complications
- Iatrogenic pneumothorax after central venous catheterization, biopsy, or positive-pressure ventilation when clinically significant.
A moderate to large pneumothorax generally requires a chest tube, whereas a small, stable, asymptomatic pneumothorax may often be observed or aspirated depending on cause and local protocol. Rosen’s Emergency Medicine notes that traumatic pneumothorax with deterioration requires immediate chest-tube insertion, and that moderate to large pneumothoraces are treated with tube thoracostomy. The Textbook of Family Medicine also identifies ventilation-compromising pneumothorax, pneumothorax over 25%, recurrence after needle thoracostomy, pleural pus, and traumatic hemothorax as indications.
For a concise patient-oriented summary, the
NHS chest-drain guidance lists air, fluid, pus, and blood in the pleural space as the main reasons for drainage.
