What is the rationale for surgical draping?

• A. Provide a wide sterile area around the surgical site
• B. Cover the entire patient
• C. Keep the room cool
• D. Reduce noise in the operating room

Answer: (A)

Draping is done to establish and maintain a sterile field around the operative site. By providing a wide sterile area around the incision, the drapes shield the wound from skin bacteria and other contaminants in the environment, reducing the risk of surgical site infection. The barrier also helps contain fluids and permits the surgeon to work with clean margins while exposing only what's necessary for the procedure. Covering the entire patient and other non-sterile surroundings isn’t necessary for sterility and can impede access or waste sterile materials. Environmental factors like room temperature or noise don’t relate to the purpose of draping.
