The present invention provides a wound dressing composed of a hydrogel with the principal component being a vinyl alcohol polymer of a viscosity average polymerization degree of 300 or more, wherein the vinyl alcohol polymer contains 5 to 50 mol % of one or more vinyl ester units represented by the following formula (I): <IMAGE> (I) and the vinyl alcohol polymer has a block character ( eta ) of 0.6 or less, the block character being represented by the following mathematical formula (II); eta =[OH, VES]/2[OH][VES](II) Because the wound dressing of the present invention is excellent in terms of transparency, flexibility, hot water resistance, water absorption, and safety, the dressing is useful for the treatment and promotion of the healing of wounds including general wounds such as abrasions, cuts and acne; surgery wounds such as excision wounds and dermabrasions; burns; ulcers; and pressure sores. |
