Antibiotic prophylaxis for post-operative wound infection in clean elective breast surgery

Antibiotic prophylaxis has been used to good effect in the prevention of post-operative wound infections in patients undergoing gastrointestinal operations. We have assessed the use of a single dose of intravenous antibiotic (Augmentin 1.2 g), given with induction of anaesthesia as prophylaxis, against post-operative wound infection in women undergoing clean, elective breast surgery. Three hundred and thirty-four patients were recruited. Of the 164 receiving antibiotic prophylaxis 29 (17.7%) had wound infections compared with 32 (18.8%) in the placebo group (P=0.79). There were no significant differences in any other post-operative infective complications. Antibiotic prophylaxis is probably not required in clean, elective breast surgery.
