Reduction of postoperative infection in elective colon surgery with preoperative administration of kanamycin and erythromycin.

Abstract

The results of a randomized prospective preoperative antibiotic study in colon surgery is presented. Antibiotics were given by mouth for 2 days prior to operation: kanamycin (1 gm four times a day) and erythromycin (750 mg three times a day). Kanamycin combined with erythromycin significantly reduced wound infection as compared to kanamycin with a placebo (three of 38 vs. 16 of 39, P less than 0.001). Thus oral aminoglycoside given alone appears to be inadequate to offer protection against postoperative infection in elective colon surgery.
