HAP / VAP

Respiratory

Common organisms

  • Pseudomonas
  • MRSA
  • ESBL Enterobacterales
  • Acinetobacter

Empirical therapy

  • Piperacillin-tazobactam 4.5 g IV q8h + Vancomycin (if MRSA risk)
  • Add aminoglycoside if septic shock or local MDR risk

Culture-directed

  • Per culture and sensitivity
  • Pseudomonas: dual cover initially, de-escalate
Renal adjustment: Piptaz: q12h if CrCl 20-40. Vancomycin: trough-guided.

Adverse effects

  • Nephrotoxicity (aminoglycoside, vancomycin)
  • Red-man syndrome (vanco infusion)

Monitoring

  • Vanco trough 15-20 mg/L for HAP
  • Daily RFT, drug levels

Clinical pearls

  • Local antibiogram dictates choice
  • Duration 7 days unless complicated

Educational support only — follow local antibiogram and institutional protocols.
