ABSTRACT:
A fenestrated surgical drape includes a "critical zone" panel surrounding the fenestration. The "critical zone" panel comprises an upper absorbent panel and underlying, upper and lower barrier panels. The absorbent layer and upper barrier panel are joined as a first sub-assembly. The lower barrier panel and the main panel of the drape are joined as a second sub-assembly. The sub-assemblies are joined by stitching marginally of the fenestration. The first sub-assembly is then joined to the lower barrier panel by stitching marginally of its outer periphery. The marginal edge portions of the "critical zone" panel are folded inwardly to form liquid receiving troughs along the side and end edges of the "critical zone" panel. These troughs intersect at the corners of the "critical zone" panel. Further folded portions of the "critical zone" panel close the intersecting ends of the troughs. Snap fastener elements hold the marginal portions of the "critical zone" in these folded relations. The snap fastener elements are releasable to facilitate laundering of the surgical drape. Tube loops are provided for releasably holding electrical instruments employed in a surgical procedure. The construction of the tube loops protects a patient against electrical shock and/or burns.
