ABSTRACT:
The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from carboxylic-oxidized cellulose and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix substantially homogeneously distributed on the first and second surfaces and through the fabric, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable cellulose polymer, wherein prior to distribution of the polymeric matrix on and through the fabric, the fabric contains about 3 percent by weight or more of water-soluble oligosaccharides.
