What is the primary purpose of a surgical drape during an orthopedic procedure?

The primary purpose of a surgical drape during an orthopedic procedure is to maintain a sterile field and prevent contamination of the surgical site. Surgical drapes are specifically designed to create a barrier against microorganisms, reducing the risk of infection and ensuring that the area where the surgery will be performed remains clean. This is crucial in orthopedic surgeries, where the use of implants and the exposure of bone can increase the risk of postoperative infections.

While providing warmth to the patient, absorbing blood, and securing the patient are important considerations during surgery, they are not the primary roles of a surgical drape. Drape materials are not specifically engineered for insulation or absorption; rather, their main function focuses on creating a controlled environment that is free from contaminants. This preservation of sterility is essential for patient safety and successful surgical outcomes.
