A surgical drape is a sterile sheet used to create a sterile field during surgical procedures with the purpose of preventing the spread of infection from non-sterile to sterile areas and protecting the patient from contamination.

The use of surgical drapes is a standard procedure in modern surgery and is recommended by many professional organizations, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC).

[1][2] Surgical drapes come in various shapes and sizes, including those that are made of materials resistant to penetration by liquids and microorganisms.

The drapes are placed over the patient and surrounding areas to create a sterile field.

[3] Some studies have shown that the use of surgical drapes reduces the incidence of surgical site infections (SSIs), which are suggested to be a significant cause of morbidity and mortality in surgical patients, as well as hospitalization costs.
