Cefazolin vs moxalactam? A double-blind randomized trial of cephalosporins in head and neck surgery

Cefazolin and moxalactam were compared in a prospective randomized double-blind trial of 118 patients undergoing oncologic head and neck surgery. Both antibiotics were given 2 g every four hours for four doses. Five infections were encountered in the cefazolin group (8.5%) and two infections in the moxalactam group (3.4%); this difference was not statistically significant. This assessment does not indicate, however, that the two regimens are equally efficacious.
