Empyema Algorithm (Children's Mercy Kansas City)

In brief
In brief
Institutional clinical algorithm from Children's Mercy Kansas City for standardized diagnosis and management of pediatric empyema. Provides evidence-based decision pathways for imaging, drainage procedures, antibiotic therapy, and surgical intervention criteria.
- Loculations or pleural fluid WBC >10,000/L indicate need for chest tube placement with 3 doses of tPA for empyema management.
- If drainage decreases without clinical improvement, obtain ultrasound or CT to assess for persistent pleural space disease.
- Persistent pleural disease on imaging after tPA therapy warrants VATS (video-assisted thoracoscopic surgery) intervention.
- Absence of pleural space disease on follow-up imaging allows continuation of antibiotic therapy alone without surgical intervention.
- Algorithm provides stepwise approach: drainage → imaging reassessment → surgical escalation only if persistent disease confirmed.
Written by the GCMD Library team from the guideline.
Initial Assessment and Chest Tube Placement
Patients with empyema presenting with loculations or white blood cell count greater than 10,000/L should undergo chest tube placement. The chest tube should be administered with three doses of tissue plasminogen activator (tPA) to facilitate drainage and fibrinolysis.
Evaluation of Treatment Response
Following initial chest tube and tPA therapy, clinical improvement and drainage output should be assessed. If drainage decreases but clinical improvement is inadequate, further imaging with ultrasound or CT is indicated to evaluate for persistent pleural space disease.
Management of Persistent Pleural Disease
When imaging demonstrates persistent pleural space disease despite chest tube drainage, video-assisted thoracoscopic surgery (VATS) is recommended for definitive management. VATS allows for debridement of fibrinous material and complete drainage of the empyema cavity.
Management Without Persistent Pleural Disease
If follow-up imaging shows resolution of pleural space disease, surgical intervention is not required. Patients should continue antibiotic therapy with ongoing clinical monitoring until complete resolution of infection.
