A 22-year-old man presented to a rural Ugandan clinic with three months of progressive dyspnea. He described a non-productive cough and subjective fevers and chills. He appears mildly dyspneic but is in no acute distress. His has a temperature of 37.7°C, pulse of 112 beats per minute, respiratory rate of 22 breaths per minute, blood pressure of 105/50 mmHg and an oxygen saturation of 93% on room air. Examination reveals absent breath sounds over the left chest. Chest radiograph demonstrates a massive fluid collection in his left hemi-thorax (Figure 1). Subsequent tube thoracostomy was productive of over three liters of purulent material (Figure 2). The patient tolerated the procedure without complication and was started on broad-spectrum antibiotics. AFB studies were eventually negative, but he was lost to follow-up.
Patients with massive empyema, although uncommon in this country, are likely to be more frequently encountered as international medicine experiences increase. The early goals of empyema therapy include evacuation of the purulent collection, sterilization of the pleural cavity, and lung re-expansion.1 Drainage requires aggressive management, such as large bore (at least 28 French) tube thoracostomy, with or without fibrinolytic therapy. The outer fibrin pleural peel of the empyema must be penetrated.
Complications from evacuating massive empyemas include re-expansion pulmonary edema (in adults from any cause and in children with malignant lymphoma), hemorrhage, secondary infection, pneumothorax and esophagopleural fistulas.2,3 To prevent these complications, sterile technique is required and image guidance by computed tomography and/or ultrasound may be useful. It is recommended that no more than 1500 mL of fluid be drained at one time or that the drainage be limited to no more than 500 mL/hour.4 Incomplete drainage may be attributed to pleural loculations or tube clogging, kinking or malposition.3 Debridement via video-assisted thoracoscopy or open thoracotomy may be required.5
