Abstract
Abstract There is provided an improved surgical drape with a central sheet having at least one hole therein through which surgical procedure is to be performed. A pair of elongated pleats are formed in the central sheet along its outer edge, providing barriers to fluid which runs off from the site of surgical procedure and further directing the fluid along a portion of the central sheet so that fluid is more readily absorbed or contained. A pair of plastic sheets are connected to the central sheet on either side of the pleats.
