1471. Evaluation of Antibiotic De-escalation in Post Cardiac Arrest Patients with Culture-Negative versus Culture-Positive Aspiration Pneumonia

摘要

Cardiac arrest patients are often empirically treated for aspiration pneumonia with broad-spectrum antibiotics. Previous literature has shown no difference in clinical outcomes when discontinuing antimicrobial therapy for suspected aspiration pneumonia with negative respiratory cultures, but the application is limited in this population. This study aimed to assess antibiotic de-escalation practices for suspected aspiration pneumonia in post cardiac arrest patients with respiratory cultures and explore clinical outcomes.
