Learn About Empyema
Empyema is a collection of pus in the space between the lung and the inner surface of the chest wall (pleural space).
Empyema - pleural; Pyothorax; Pleurisy - purulent
Empyema is usually caused by an infection that spreads directly from the lungs. It leads to a buildup of pus in the pleural space. This fluid puts pressure on the lungs.
Risk factors include:
- Bacterial pneumonia
- Tuberculosis
- Chest surgery
- Lung abscess
- Trauma or injury to the chest
In rare cases, empyema can occur after thoracentesis. This is a procedure in which a needle is inserted through the chest wall to remove fluid in the pleural space for medical diagnosis or treatment.
Symptoms of empyema may include any of the following:
- Chest pain, which worsens when you breathe in deeply (pleurisy)
- Dry cough
- Excessive sweating, especially night sweats
- Fever and chills
- General discomfort, uneasiness, or ill feeling (malaise)
- Shortness of breath
- Weight loss (unintentional)
The goal of treatment is to cure the infection. This involves the following:
- Placing a tube in your chest to drain the pus
- Giving you antibiotics to control the infection
If you have problems breathing, you may need surgery to help your lungs expand properly.

When empyema complicates pneumonia, the risk for permanent lung damage and death goes up. Long-term treatment with antibiotics and drainage is needed.
In general, most people fully recover from empyema.
Having empyema may lead to the following:
- Pleural thickening
- Reduced lung function
Contact your provider if you develop symptoms of empyema.
Prompt and effective treatment of lung infections may prevent some cases of empyema.
Summary: Intercostal chest drain (ICC) insertion is a common procedure done worldwide to treat and diagnose pleural disease. It is used to evacuate fluid, blood, or air in the cavity from a myriad of causes namely pleural effusions of different etiologies, empyema, hemothorax, chylothorax and pneumothorax. It also functions as a route for antibiotics, pleurodesis and fibrinolytics. Hippocrates, whose pract...
Summary: This prospective observational study aims to investigate the frequency and clinical significance of biofilm formation on thoracic chest drains used after thoracic surgery. Biofilms are structured bacterial communities that adhere to surfaces and can promote infection and antibiotic resistance. In this study, small samples from the tips of chest drains will be collected under sterile conditions at ...
