AbstractA prospective, randomized study was carried out to evaluate two antibiotic prophylactic regimens for patients undergoing cardiac surgery with cardiopulmonary bypass. Each patient of the first group (cefazolin) received four intravenous injections of 1 g cefazolin during 12 hours, patients of second (cefamandole), four doses of 750 mg. 155 patients scheduled for cardiac operation were included in the study. (May 1983 to April 1984). Patients were not admitted to the study in case of emergency, if their weight was less than 20 kg, if they had received antibiotics during the week before surgery or if they had a history of anaphylactic reactions to cephalosporins. There were no differences between the two groups on age, weight, height, sex, previous history of infectious disease, surgery and intensive care. There were no significant differences between the two groups in minor infections. The rate of urinary tract infection by streptococci was significatively higher (p less than 0.02) in the cefamandole group (38.3%) than in the cefazolin group (17.6%). There were no major infections (septicemia, mediastinitis, endocarditis). Patients temperature was the same during the first four postoperative days. Hospital stay was the similar in the two groups. The two antibiotics are similarly effective to prevent major infections in cardiac surgery. However cefazolin was preferred for antibiotic prophylaxis in cardiac surgery because of the higher rate of streptococcal urinary infections in patients given cefamandole.
