Antibiotic prophylaxis in clean surgical cases and the role of community surveillance

Abstract

In an ongoing prospective study of clean surgical procedures, patients have been examined by specialist research nurses on a minimum of three occasions during the postoperative period to determine the incidence of wound complications. Whereas a previous retrospective audit suggested a wound infection rate of 2%, this community surveillance programme revealed the true rate as at least fourfold greater (p less than 0.001). Of these complications, more than 70% were detected only by the surveillance programme. Immediate benefit was obtained by a reduction in all complications. Despite these improvements, a core of postoperative sepsis remained, particularly in high-risk cases. Thus, a prospective, controlled, prophylactic antibiotic trial has been undertaken, in an attempt to reduce the infection rate still further. An antibiotic regimen of teicoplanin, 400 mg i.v., given as a single dose, was chosen because of the excellent activity of this agent against staphylococci and streptococci, and also because of the long half-life which renders it suitable for single-dose administration.
