A dual function medical pad is disclosed for both controlling patient temperature and providing a patient-to-electrode interface. The pad includes a fluid containing layer for containing a thermal exchange fluid circulated therethrough, wherein the medical pad is operable for thermal exchange with a patient through a first side of the fluid containing layer. One or more electrodes are interconnected to the fluid containing layer on the first side (e.g. electrosurgical return electrode(s), EKG electrode(s), pacing/defribullation electrode(s)). Preferably, an electrical connector is electrically connected to the electrode and extends through the fluid containing layer to a second side thereof. Such electrical connector is interconnected or selectively interconnectable to a signal cable. The pad may further include an adhesive surface which extends over at least a portion of the first side of the fluid containing layer. Preferably, the adhesive surface substantially covers the electrode(s). The adhesive surface may be defined by a conformable layer that is thermally and electrically conductive. Such conformable layer may comprise a first material suspended in a matrix defined by a second material (e.g. a liquid suspended in a polymer matrix). The medical pad can be used with an electrosurgical generator (160) and a defibrillation/pacing system (150).Linvention concerne un coussinet médical à deux fonctions permettant à la fois de réguler la température dun patient et de fournir une interface entre ce patient et une électrode. Ledit coussinet comprend une couche renfermant un fluide déchange thermique circulant dans ladite couche, ce coussinet permettant deffectuer un échange thermique avec le patient par lintermédiaire dun premier côté de la couche renfermant un fluide. Une ou plusieurs électrode(s) sont interconnectées avec la couche renfermant le fluide (par exemple, une ou des électrode(s) électrochirurgicale(s) de retour, une ou plusieurs électrode(s) EKG et une ou
