Empyema / Complicated Parapneumonic Effusion
CC: Pneumonia not improving, pleuritic chest pain, fever
PP: Persistent fever, leukocytosis, dyspnea, pleuritic pain, loculated effusion
PN: No PE/CHF-only picture unless present
pertinent SHx: Aspiration risk, alcohol use, poor dentition, recent pneumonia
Etiology: Infected pleural space complication of pneumonia/aspiration
risk factors: Delayed pneumonia treatment, aspiration, immunosuppression, lung disease
initial DATA: CBC, CMP, blood cultures if febrile, CXR, CT chest with contrast, thoracentesis
pending DATA: Pleural fluid pH, glucose, LDH, protein, cell count, gram stain/culture
prior data: Prior CXR/CT, antibiotics
MEDS: Recent antibiotics, anticoagulation
COURSE:
Plan:
Antibiotics:
Community: Ceftriaxone + Metronidazole
Healthcare-associated/severe: Vancomycin + Cefepime + Metronidazole
Aspiration/oral anaerobes: Ampicillin-sulbactam or Ceftriaxone + Metronidazole
Diagnostic thoracentesis if safe
Chest tube if:
Frank pus
Positive gram stain/culture
pH <7.2
Low glucose
Loculated/large complicated effusion
Pulm/IR consult for thoracentesis/chest tube
Thoracic surgery if persistent loculations, trapped lung, failed drainage
Trend CBC/O2 needs/fever curve
Pulmonary hygiene/O2 support
Duration: usually 2–6 weeks depending drainage and response
