AbstractWith a view of possible reduction in antibiotic dosage, several prospective randomized comparative trials performed in our institution showed that a 4-day prophylactic antimicrobial regimen with cefazolin was equally effective as a 2-day prophylaxis with cefuroxime and that the best regimen was equally as effective as a double dose of ceftriaxone prophylaxis in major cardiovascular surgery. In this prospective randomized comparative study, 1-day cefazolin prophylaxis (4 X 0.5 g intravenously) was compared with a single dose of ceftriaxone prophylaxis (2 g intravenously). Of the 900 patients enrolled in the study, 17 were subsequently excluded. Of the remaining 883 patients, 439 were in the cefazolin group and 444 were in the ceftriaxone group. The overall postoperative infection rate was 5.0% in the cefazolin group and 4.5% in the ceftriaxone group. In view of the almost identical infection rates in both groups, we considered that a single 2 g dose of ceftriaxone offers patients a reliable antimicrobial prophylaxis. The single-dose prophylaxis has the additional advantage of reducing the dosage administered and the costs of administration.
