Primary outcomePrimary: Time to Normothermia — 4.4 hours
Summary
Hypothermia on admission to the intensive care unit (ICU) following cardiopulmonary bypass (CPB) is common. The investigators propose that rewarming hypothermic (≤ 35 C) patients admitted to the intensive care unit following procedures using CPB with heated humidified breathing circuits (HHBC) in addition to conventional forced air warming blankets will shorten time to normothermia. Secondarily it may shorten time to extubation, improve coagulopathy, and metabolic derangements seen with hypothermia.
