Achieves therapeutic levels via systemic administration
Intrapleural administration offers no additional benefit
No role for aminoglycosides
Inactivated by acidic pH of empyema fluid
Avoid even when organism appears sensitive in vitro
Surgical decision timing
Early VATS consideration at 3 to 5 days of medical failure
Waiting longer allows Stage 3 organization
Earlier intervention associated with better outcomes
Involving thoracic surgery early prevents delayed decision
Patient Discharge Instructions
copy discharge instructions
Empyema home care instructions
Complete all antibiotics as prescribed
Course may be 3 to 6 weeks total
Do not stop early even if feeling better
Activity
Rest until breathing comfortable at rest
Gradually increase activity as tolerated
Drain care if discharged with drain in place
Keep drain site clean and dry
Record daily drain output
Cover with sterile dressing changed as instructed
Nutrition
High protein diet to support recovery
Small frequent meals if appetite poor
Warning signs to return to ER immediately
Worsening shortness of breath at rest
Breathing harder than before discharge
Unable to speak full sentences
Chest pain worsening

Redness, swelling, pus, or warmth at site
Confusion or unusual drowsiness
Blue lips or fingertips
Coughing up blood
Follow-up instructions

Assess for trapped lung or residual thickening
Family doctor or primary care within 1 week of discharge
Antibiotic review and tolerance assessment
Return for scheduled drain removal if applicable
