  1. In patients who were randomly assigned to either aggressive warming with targeted intraoperative temperatures of 37.0°C or routine thermal care with temperatures around 35.5°C, there were similar incidences of myocardial injury (9.9% vs 9.6%), surgical site infection (7.2% vs 6.3%), and need for transfusion (10% vs 9.5%).
  2. Over a range of 1.5°C—from very mild hypothermia to full normothermia—there was no evidence of any substantial effect on patient outcomes. The maintenance of core temperature of ≥35.5°C in surgical patients appears to be sufficient to avoid major hypothermia-related complications.
