Abstract
We have prospectively studied the effect of 1-day prophylactic antibiotic therapy in lower-limb amputation for ischaemia. Twenty-seven patients were treated with Meticillin 1 g × 4 intravenously on the day of operation; 23 control patients did not receive any antibiotics. Eight patients in the control group had postoperative wound infections compared to none in the Meticillin group. Seven patients were re-amputated because of infection. Preoperatively, Staphylococcus aureus was isolated in 5/8 of the patients in the Meticillin and 6/8 in the control group. In the postoperatively infected stumps, S. aureus occurred in 6/8 of the patients in the control group, and one patient developed gas gangrene.
