Abstract: An improved medical pad for contact thermal exchange with a patient includes a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough, a first port and a second port for circulating the thermal exchange fluid in to and out of the fluid circulation layer, and a hydrogel layer interconnected to and extending across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin. The hydrogel layer comprises an ultra violet light-cured composition that includes a cross-linking copolymer in an amount of between about 15% to 30% by weight of the composition, water in an amount of between about 15% to 40% by weight of the composition, and glycerol in an amount of between about 25% to 35% by weight of the composition. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 cal/hr-cm-° C.
