What is the rationale for adhesive incise drapes around an incision?

• A. They prevent anesthesia from leaking into tissues.
• B. They brace tissues mechanically.
• C. They create a barrier around the incision to reduce microbial migration from skin to wound.
• D. They increase adhesive properties for sutures.

Answer: (C)

The main idea is that adhesive incise drapes create a barrier around the incision to reduce microbial migration from skin to the wound. By isolating the incision from surrounding skin flora, the drape lowers the chance that bacteria on the skin contaminate the wound during surgery. Some drapes may be impregnated with antiseptics, but the core rationale is the physical barrier that minimizes transfer of skin microbes into the incision. They do not function to prevent anesthesia leakage, brace tissues, or enhance suture adhesion.
