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
