A single-use patient positioning and warming pad configured to be placed between a patient and an operating table during a surgical procedure is provided. The pad includes a viscoelastic foam body having a top portion and a bottom portion； a heating element at least partially disposed between the top portion and the bottom portion of the foam body； and an electrical connector having a proximal end portion enclosed within the foam body connected to the heating element and a distal end portion extending from the foam body, configured to directly or indirectly connect to a power source and/or control unit for the heating element. Optionally, the foam body is formed from a foam material having sufficient viscosity and resiliency to maintain positioning of the patient relative to the operating table during surgical procedures in which the operating table is moved to an inclined position.
