Abstract
The efficacy and toxicity of moxalactam were compared with the efficacy and toxicity of cefoxitin given with or without tobramycin to 109 patients with surgical infections. A total of 66 patients could be assessed for efficacy (33 patients in each group); 13 of the cefoxitin-treated patients also received tobramycin for at least 72 h. Most patients had intraabdominal infections; 17 had peritonitis, 14 had intraabdominal abscesses, and 7 had perforation of a gangrenous appendix. There were 15 patients with necrotizing soft-tissue infections. The predominant pathogens were members of the Enterobacteriaceae and Bacteroides fragilis. The cure rates were 79% (26 of 33 patients) for moxalactam and 88% (29 of 33 patients) for cefoxitin; the difference in cure rates was not statistically significant. In several patients, cultures of purulent intraabdominal exudates were negative, although bacteria were observed after Gram staining; this presumably reflected the potent activity of the antibiotic therapy which had been started before surgical drainage could be carried out. Adverse effects were observed in 18 of 44 assessable patients (41%) in the cefoxitin group and in 12 of 36 patients (33%) in the moxalactam group; the difference in the rates of adverse effects was not statistically significant. Our results suggest that moxalactam is similar in efficacy and toxicity to cefoxitin given with or without tobramycin for the treatment of serious surgical sepsis caused by a mixture of anaerobic and aerobic pathogens.
