2.Secondary Outcome
Title Safety as Assessed by Number of Adverse Events Reported Per Participant
Hide Description Adverse events were graded according to the USDHHS Common Terminology Criteria for Adverse Events V4.0. Serious adverse events and pre-defined adverse events of interest that historically were known to be of concern with hypothermia treatment were selected to be monitored and reported regardless of grade. These included cardiac arrhythmias, thromboembolic events, pneumonia, bleeding or hemorrhage, intraoperative hemorrhage, infection (culture positive, e.g., blood stream infection, urinary tract infection, ventriculitis), device-related infection, and death. The number of adverse events per participant were compared between groups.
