Abstract
Abstract A method of draping a surgical patient in which a bottom drape is first attached to a patient, and then a top drape having an opening smaller than the bottom drape is secured by an adhesive to the top surface of the bottom drape to expose a portion of the bottom drape through the top drape's opening. The bottom drape can have the desired shape and size of fenestration, a high degree of liquid repellency, germicidal treatment, etc., while the top drape can be less liquid repellent, giving it a more drapeable, cloth-like characteristic.
