Abstract

A dressing incorporates free acid cellulose glycolic acid ether or free acid cellulose hydroxypropionic acid ether as a haemostatic agent. The substance may be incoporated in a gauze dressing or sponge for application to a wound or it may be applied in bone wax. Additionally, the dressing may comprise a poly-ol compound such as glycerine to prevent adhesion of the dressing to the clot. The acid cellulose ether may be added to the dressing by means of any of its soluble salts, soluble forms of the acid itself or by synthesis of the cellulose ether on cellulose fibres. In a preferred procedure the ammonium salt is made by direct contact of free acid carboxymethyl or carboxyethyl cellulose powder with concentrated aqueous ammonium hydroxide solution. The ammonium salt is then diluted and applied directly to the surgical composition. Then, after drying, the material is heated to decompose the ammonium salt into ammonia and free acid cellulose derivative. This is perferably subjected to further heat treatment to render it partially insoluble in water.
