- ESBL-E: Carbapenems are often the first-line choice due to their efficacy against ESBL-producing organisms. Cefepime and Ceftazidime-Avibactam are alternatives. Ceftolozane-tazobactam 有效但保留給both DTR P. aeruginosa and ESBL-E.
- AmpC-E: Carbapenems and Cefepime are preferred for their resistance to degradation by AmpC enzymes. Piperacillin-Tazobactam can be considered if susceptibility is confirmed.
- CRE: Ceftazidime-Avibactam and Meropenem-Vaborbactam are the top choices for CRE due to their effectiveness against these highly resistant organisms. Traditional carbapenems are not effective against CRE.
- DTR P. aeruginosa: Ceftolozane-Tazobactam and Ceftazidime-Avibactam are effective against most resistant P. aeruginosa strains. Other options may work if susceptibility is demonstrated.
- CRAB: Treatment includes Colistin and Sulbactam as first-line agents, with Tigecycline and Minocycline as alternatives. Imipenem is generally not recommended due to resistance.
- Stenotrophomonas maltophilia: TMP-SMX is the treatment of choice, with Levofloxacin and Minocycline as secondary options. Beta-lactams are not effective.
