Prophylaxis in appendicectomy with cefoxitin or ceftriaxone.
Two hundred and forty adults undergoing acute appendicectomy were randomised to receive either cefoxitin or ceftriaxone 1 g intravenously at induction of anaesthesia. Patients were monitored daily while in hospital, and at least 4 weeks after discharge for evidence of wound, urinary or lower respiratory tract infection. We evaluated 167 patients at follow up and found no significant difference in infection rates between the two antibiotic groups. Thirty-four had normal appendices and 1 of 16 (6.3%) given cefoxitin and 2 of 18 (11.1%) given ceftriaxone developed wound infections. Ninety-seven had acute appendicitis and 3 of 48 (6.3%) given cefoxitin and 3 of 49 (6.1%) given ceftriaxone developed infections including 2 wound infections in each group. Thirty-six had gangrenous perforated or abscessed appendices: 31 were given additional antibiotics postoperatively, and 4 of 18 (22.2%) in each prophylactic antibiotic group developed infections, including wound infection in 3 given cefoxitin and in 4 given ceftriaxone. None of the infections were serious. Sixty-one percent presented after discharge from hospital. The mean hospital stay was 4.6 days for each antibiotic group. Neither antibiotic caused adverse effects.
