How do you treat empyema?

Drainage. Empyema or pus in the space around the outside of the lungs usually needs drainage and treatment with antibiotics directed against the causative agent (bacteria, tuberculosis, etc.). Sometimes surgical intervention may be necessary.
Agree. The mainstay of treatment is early recognition, drainage, complete lung re-expansion, and targeted antibiotics. When indicated, modern thoracic surgical treatment of empyema uses minimally invasive techniques. Thoracotomy is often unnecessary (and potentially more dangerous) approach.
