Single-dose cefotetan or cefoxitin versus multiple-dose cefoxitin as prophylaxis in patients undergoing appendectomy for acute nonperforated appendicitis.

Abstract

OBJECTIVE: A prospective, double-blind study was performed to examine the effects of prophylactic cefotetan and cefoxitin in postoperative wound infection for patients with nonperforated acute appendicitis. METHODS: One hundred thirty-six of 179 patients with a clinical diagnosis of appendicitis were evaluated and divided into three groups: group 1 received 2 g cefotetan preoperatively, group 2 received 2 g cefoxitin preoperatively, and group 3 received 2 g cefoxitin preoperatively followed by three postoperative doses. RESULTS: The overall wound infection rate was 4.6 percent. Group 2 (single-dose cefoxitin) had a significantly higher wound infection rate (11.1 percent) than group 1 (single-dose cefotetan) (zero percent) or group 3 (multiple-dose cefoxitin) (1.9 percent). CONCLUSIONS: Single-dose cefotetan and multiple-dose cefoxitin are equally effective. However, because of the greater convenience and markedly decreased cost, single-dose cefotetan is the prophylaxis of choice in appendectomy for nonperforated appendicitis.
