What is the primary goal of the surgical skin preparation and draping?

• A. Sterilize the entire operating room
• B. Remove all hair from the body
• C. Reduce skin microbial flora at incision site and create a sterile field
• D. Prevent all postoperative pain

Answer: (D)

The main point of surgical skin preparation and draping is to lower the number of skin microbes at the incision site and to establish and maintain a sterile field for the operation. By applying antiseptic solution to the skin in a careful pattern that starts at the incision area and moves outward, and by using sterile drapes to cover everything except the prepared area, the risk that skin bacteria contaminate the wound is minimized. Hair removal, if needed, is not done broadly or aggressively—ideally with clippers if necessary—to avoid skin injury that can become a bacterial habitat. It’s not about sterilizing the entire operating room, and it won’t prevent postoperative pain, which is managed through anesthesia and analgesia.
