Indications for Chest Tube Placement

Primary Indications

The American Thoracic Society recommends chest tube placement for pneumothorax, hemothorax, pleural empyema, complicated parapneumonic effusions with specific biochemical criteria (pleural pH <7.2), and large symptomatic pleural effusions 1
Pleural infection, where pleural fluid pH <7.2 predicts the need for drainage, should trigger immediate chest tube placement, according to the British Thoracic Society 1, 2
Frank pus (empyema) always requires chest tube drainage, as stated by the American College of Chest Physicians 1, 2, 3
Loculated pleural collections require earlier chest tube drainage due to association with poorer outcomes, as recommended by the European Respiratory Society 1, 2, 4
Large pleural collections (>40% of hemithorax) are more likely to require surgical intervention and warrant chest tube placement, according to the Society of Thoracic Surgeons 1, 4

The American College of Chest Physicians recommends that large pneumothoraces always require chest tube placement regardless of clinical stability 5
Small pneumothoraces require chest tube placement only if the patient is clinically unstable, as stated by the American Thoracic Society 5
Clinically stable patients with small pneumothoraces may be observed closely in the outpatient setting, according to the British Thoracic Society 5

Non-purulent effusions without acidosis should be drained by chest tube for symptomatic benefit when they are large and causing respiratory compromise, as recommended by the American College of Chest Physicians 1, 2, 4

The Infectious Diseases Society of America recommends that small, uncomplicated parapneumonic effusions should NOT be routinely drained and can be treated with antibiotics alone in children with community-acquired pneumonia 6
Moderate effusions with respiratory distress, large effusions, or documented purulent effusions require drainage, according to the Pediatric Infectious Diseases Society 6
Loculated effusions cannot be drained with chest tube alone and require adjunctive therapy (fibrinolysis or VATS), as stated by the Society for Pediatric Research 6

A respiratory physician or thoracic surgeon should be involved in all cases requiring chest tube drainage for pleural infection, as recommended by the European Respiratory Society 1, 2, 3, 4
Delay in chest tube drainage is associated with increased morbidity, prolonged hospital stay, and potentially increased mortality, according to the American College of Chest Physicians 1, 2, 4
Never use trocars for chest tube insertion due to high risk of intrathoracic organ damage, hemothorax, and lung lacerations, as stated by the British Thoracic Society 7
Delay in drainage significantly worsens outcomes—misdiagnosis, inappropriate antibiotics, and inappropriate tube placement contribute to progression of pleural infection, according to the American Thoracic Society 1, 2, 4

Clinically stable patients with small pneumothoraces may be observed closely in the outpatient setting, according to the Pulmonology guidelines 8
Spontaneous primary pneumothorax can be managed outpatient with needle aspiration if the patient is minimally symptomatic and risk assessment allows, as recommended by the Pulmonology guidelines 8
Small effusions (<10mm rim) do not require drainage and can be treated with antibiotics alone, as suggested by the Clinical Infectious Diseases guidelines 9
Moderate effusions (>10mm but <50% hemithorax) can be treated with IV antibiotics alone if bacterial culture/Gram stain is negative and low respiratory compromise is present, according to the Clinical Infectious Diseases guidelines 9
Large effusions (>50% hemithorax) should be drained in most cases, especially with respiratory compromise, as recommended by the Clinical Infectious Diseases guidelines 9

On suspicion of malignant effusion, diagnostic pleural fluid aspiration should be performed, especially if the patient is a candidate for systemic therapy or if the effusion is symptomatic, as suggested by the Pulmonology guidelines 8

Extra care must be taken when placing chest tubes to avoid open communication with the pleural space and potential emission of droplets and aerosols, as recommended by the Pulmonology guidelines 8
