1. A method for making a medical pad for contact and thermal exchange with a patient, comprising:
providing a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough;
connecting a first port to the fluid circulation layer for circulating the thermal exchange fluid into the fluid circulation layer;
connecting a second port to the fluid circulation layer for circulating the thermal exchange fluid out of the fluid circulation layer; and
adding a hydrogel layer to the fluid circulation layer so that the hydrogel layer extends across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin, the hydrogel layer including an ultraviolet light-cured composition, wherein:
the ultraviolet light-cured composition comprises:
a cross-linking copolymer in an amount of between about 25% to 30% by weight of the ultraviolet light-cured composition;
water in an amount of between about 25% to 35% by weight of the ultraviolet light-cured composition; and
glycerol in an amount of between about 27.5% to 32.5% by weight of the ultraviolet light-cured composition; and
the hydrogel layer has a thermal conductivity of between about 1.9 cal/hr-cm-° C. and 2.37 cal/hr-cm-° C.
