A wound dressing comprising a sheet of a hydrophilic foam material, wherein a surface of the sheet is coated with a substantially anhydrous warming composition comprising one or more polyol warming agents. The polyol warming agent interacts with the water present in wound fluid to provide a temperature increase and warming effect. In one embodiment the hydrophilic foam sheet is patterned with an array of partial thickness indentations. In another embodiment the hydrophilic foam layer comprises at least 50 % by weight of a polyurethane and the warming polyols comprise one or more polyols such as polyethylene glycol (PEG), PEG ethers, PEG block copolymers, alkylene glycols, and mixtures thereof. Also provided is a method of making such a wound facing sheet comprising the steps of: providing a layer of a hydrophilic foam material, and coating a surface of said layer with a substantially anhydrous warming composition comprising one or more polyol warming agents. |
