We investigate the claim that an alternative antibiotic to cephalosporins (e.g., cefazolin) should be selected for penicillin-allergic patients in the perioperative setting.

Claim 1. Alternative antibiotics may be as efficacious in preventing surgical site infections

Claim 2. Cephalosporins (e.g., cefazolin) may be unsafe due to cross-reactivity.

Claim 3. Administering cephalosporins (e.g., cefazolin) may be against the standard of care.

My guest this week is Dr. Matthew Vanneman, an attending cardiothoracic anesthesiologist at the Massachusetts General Hospital.
