Abstract
A surgical drape comprises a main panel and a "critical zone" panel secured thereto. A fenestration is formed by cutting through the "critical zone" panel. The main panel is a light weight fabric having a relatively high coefficient of friction. The "critical zone" panel comprises a barrier panel lying against the main panel and an outwardly facing absorbent panel, having an irregular surface. In an another embodiment, the critical "critical zone" panel is folded to form troughs for capturing liquid incident to a surgical procedure.
