Objective: We evaluated the performance of a new temperature management system (Arctic Sune, Medivance, Inc.) in maintaining normothermia during off-pump coronary artery bypass (OPCAB). Patients and methods: Ninety-eight unselected patients were prospectively randomized to either a conventional temperature management method (consisting of a sterile forced-air warming blanket, warm intravenous fluids, and maintenance of a warm OR) or the new Arctic Sun system (two pads, Arctic Sun Energy Transfer Padse placed on the patient’s back with temperature-controlled water flowing through the pads). Results: The mean age, body surface area, and total operating time were similar in both groups. Despite significantly lower room temperatures ðp, 0:001Þ in the Arctic Sun group, the system maintained higher bladder and nasopharygeal temperatures (p, 0:001 and p, 0:001, respectively). A core temperature of at least 36 8C was achieved in 97 % of the Arctic Sun patients compared with 42 % in the conventional group. Additionally, intra-operative blood loss for
