A. AI. A. Arch. Surg. 85: 456, September, 1962. For a period of eightcen ntonth~, the effect of postoperative antibiotic prophylaxis on the incidence of wound infection was studied in the surgical wards of the Hospital tlas (Ilinicas, University of Bahia, Brazil. Patients undergoing the same surgical procedures were alteruatel>treated with antibiotics. The over-all incidence of wound iufeetiou bvas 6 per cent. Among the 644 cases illeluded in the stud-, there was no difference in the incidence of infection between the treated (344 cases) and control (:iO(l cases) groups. Sluph~yylococcus ~WC Us, coagulase positive, resistaut to pfanicillin, was the Itlost COI0IuOll causative agent. It was also frequently isolated from the noses of surgical personnel and from the air of all the operating roomy’. ( ‘asctr of gran-negative or mixed infections wvrc less frequently observed. There seemed to be no aclvantsge to prophylactic postoperative antihiotic therapy as eruployed in this study. The use of such agents did not diminish the incidence of wountl infect,ion or reduce the length of hospitalizatiorl. Penicillin was the drug use{1 most frt, queutly, and the majority of infrclivr agent* were resistant to this antibiotic. IVt? do uol Ijelieve that any antibiotic is eflec:tivr over a prolonged period of time. The indiscriminate use of antibiotics in sncah situations would tend to facilitate the emergent? of rexistaul st rail13 of bacteria. 7’. .I.
