Abstract: A thermal covering that comprises a thermoregulatory substrate is provided. The thermoregulatory substrate contains an exothermic coating formed from an oxidizable metal. The exothermic coating is generally free of moisture prior to activation. Exposure of the exothermic coating to oxygen and moisture activates an exothermic reaction to generate heat, such heat being transferable to a patient or user through an outer surface defined by the thermal covering.

Abstract: A surgical drape for covering a patient during a surgical procedure is provided. The drape has a base sheet having an upper surface, a lower surface, and a plurality of edges. A fenestration is formed in the base sheet positionable over the surgical site. A reinforcement panel having an upper surface, a lower surface, and a periphery is also provided. The lower surface of the reinforcement panel has a pressure sensitive adhesive applied thereto. The panel is adjustably manipulated and adhered by the pressure sensitive adhesive so as to occlude a portion of the fenestration in the base sheet at the time of the surgical procedure.
