Abstract  Many surgeons use a single table of instruments for both excisional debridement and coverage/closure of infected wounds. This study investigates the effectiveness of a two‐table set‐up of sterile instruments, in addition to glove exchange, to reduce instrument cross‐contamination during these procedures. This is a prospective, single‐site, institutional review board‐approved observational study of surgical debridements of infected wounds over a 17‐month period. Two separate sterile surgical tables were used for each case: Table A for initial wound debridement (debridement set‐up) and Table B for wound coverage/closure (clean set‐up). Swabs of each table and its respective instruments were taken after debridement but prior to coverage/closure. The primary outcome of interest was bacterial growth at 48 hours. There were 72 surgical cases included in this study. Culture results of Table A demonstrated bacterial growth in 23 of 72 (32%) cases at 48 hours compared with 5of 72 (7%) from Table B ( P  = .001). These data suggest that there is significant bacterial contamination of surgical instruments used for debridement of infected wounds. Use of a two‐table set‐up reduced instrument cross‐contamination by 78%, suggesting avoidable re‐contamination of the wound.
