Abstract | BACKGROUND: METHODS: Using a standardized inoculum, and a predetermined randomization schedule, a porcine model was used to assess the efficacy of a CHG-impregnated adhesive drape to prevent MRSA contamination of a simulated surgical wound and intact skin surface compared with an iodophor-impregnated incise drape and a nonantimicrobial incise drape in 0, 1, and 4-hour surgeries. RESULTS: MRSA recovery from incisional wounds was lowest in sites treated with the CHG drape. The difference was statistically significant (P < .001) at all time points, both between the CHG drape and the nonantimicrobial control as well as between the CHG and iodophor drapes. Mean MRSA recovery from wounds treated with iodophor drapes was slightly lower than nonantimicrobial drapes. The difference was not statistically significant at 0- or 1-hour (P = .065 and P = .089, respectively), however the differences were significant at 4-hours (P = .024). DISCUSSION: These preliminary results show that a novel CHG surgical incise drape reduced MRSA contamination of a surgical incision site and showed significant antimicrobial activity against contamination of intact skin surfaces compared with an iodophor- impregnated drape. CONCLUSIONS: A novel CHG surgical drape was effective in significantly reducing MRSA contamination in an incisional wound model. Future studies are needed to assess its clinical efficacy.
