Intrarectal metronidazole in the prevention of anaerobic infections after emergency appendicectomy: a controlled clinical trial

Abstract

A series of 102 patients with presumptive acute appendicitis entered a prospective, randomized, clinical trial of intrarectal metronidazole given over a 48-h period commencing before surgery. Adequate levels of circulating metronidazole were achieved. A significant reduction in the incidence of anaerobic wound infection was observed in the treated group (P less than 0.02). The convenience and short duration of the prophylactic regimen allowed early discharge from hospital. No untoward effects were observed.
