- Pleural empyema
empyema(also known as a pyothorax or purulent pleuritis) is an accumulation of pusin the pleural cavity. Most pleural empyemas arise from an infection within the lung( pneumonia), often associated with parapneumonic effusions. There are three stages: exudative, fibrinopurulent and organizing. In the exudative stage, the pus accumulates. This is followed by the fibrinopurulent stage in which there is loculation of the pleural fluid (the creation of grapelike pus pockets). In the final organizing stage, scarring of the pleural space may lead to lung entrapment.
Symptoms of empyema may vary in severity. Typical symptoms include:
fever, chest painor discomfort, cough, sweating and shortness of breath. Clubbingof the fingernails may be present. There is a dull percussionnote and reduced breath sounds on the affected side of the chest. Other diagnostic tools include chest x-ray, CT scan, and ultrasonography.
Diagnosis is confirmed by
thoracentesis; frank pus may be aspirated from the pleural space. The pleural fluid typically has a low pH (<7.20), low glucose (<60 mg/dL), and contains infectious organisms.
Definitive treatment for empyema entails drainage of the infected pleural fluid. A
chest tubemay be inserted, often using ultrasound guidance. Intravenous antibiotics are given. If this is insufficient, surgical debridementof the pleural space may be required.
