What is the purpose of using a stockinette in surgical draping?

The purpose of using a stockinette in surgical draping is primarily to cover extremities during surgery. Stockinettes are stretchable, tubular fabrics that provide a sterile covering for the limbs, helping to maintain a sterile field and protect the exposed skin and soft tissues from contamination during the surgical procedure. This covering is essential to minimize the risk of infection and to ensure that the surgical environment remains as sterile as possible.

By effectively covering the extremities, stockinettes also assist in the positioning and access required for surgical operations, allowing the surgical team to focus on the procedure without concern for maintaining sterility in that area. This use is particularly important in various types of surgeries where extremities may be exposed or in a specific position, ensuring the safety and sterility of the surgical site.
