Hyperthermia during Cardiopumonary Bypass
Hyperthermia during Cardiopumonary Bypass Moderate-quality prospective studies have demonstrated that when rewarming on cardiopulmonary bypass (CPB), hyperthermia (core temperature >37.9°C) is associated with cognitive deficits, infection, and renal dysfunction. Any postoperative hyperthermia within 24 hours after coronary artery bypass grafting has been associated with cognitive dysfunction at 4 to 6 weeks. Rewarming on CPB to normothermia should be combined with continuous surface warming. Thus, we recommend avoiding hyperthermia while rewarming on cardiopulmonary bypass (class III, level B-R).
