A prospective random study of a single agent versus combination antibiotics as therapy in penetrating injuries of the abdomen

Abstract

One hundred patients undergoing operation for penetrating and potentially contaminated wounds of the abdomen were given cefamandole or a combination of cephalothin-tobramycin by a random, single blind method as preventive therapy. Results were evaluable for 49 patients receiving cefamandole for a success rate of 93.9 per cent. The 45 evaluable results in the second group had a success rate of 88.9 per cent. Those in the single therapy group also required fewer days of treatment and of hospital confinement, resulting in lower per patient cost. Results of this study show cefamandole to be an efficacious alternative for surgeons seeking a single agent therapy.
