Comparison of cefamandole and carbenicillin in preventing sepsis following penetrating abdominal trauma.

One hundred and five patients with penetrating abdominal injuries were treated with single-antibiotic regimens. Forty-seven patients were treated with intravenous (IV) cefamandole and for comparison 58 patients were treated with IV carbenicillin previously shown to be effective against postoperative infections associated with abdominal trauma. The overall incidence of deep infection on a single antibiotic therapy was 8.6 per cent, including two patients on cefamandole alone (4.3%) and seven (12.1%) on carbenicillin alone. One in each antibiotic group died of sepsis with a total mortality of 1.9 per cent. The authors concluded that cefamandole when used alone was found to be safe and more effective than carbenicillin alone in preventing sepsis in patients with abdominal trauma.
