Q

In what percentage of empyema cases will the blood culture be positive?

Q

What is the usual empiric antibiotic choice for a child with empyema?-what about for severe suspected MRSA pneumonia?-duration of treatment?

A

Ceftriaxone or cefotaxime +/- clindamycin to cover anaerobic infection or community acquired MRSA –> when improved, can switch to PO amoxi-clav-severe MRSA: consider adding vancomycin or linezolid -duration of treatment: no evidence exists for the recommended duration but usually requires total of 3-4 wks (IV, then switch to PO when afebrile, drainage of effusion is complete, clinically improved and off O2)

Q

What are the options of procedural interventions for empyema and which is the most cost-effective?-what is the dose of fibrinolytic agent used?

A
  1. VATS2. Early thoractomy3. Chest tube placement with instillation of fibrinolytics (CTWF) = most cost effective-dose of TPA (tissue plasminogen activator): 4 mg in 50 ml NS daily x 3 d)
