Summary
The purpose of this study is to determine:
1. the effect of ambient temperature on the rate of core temperature change from 1 to 3 hours after induction of anesthesia (linear phase of the hypothermia curve) in major operations lasting at least a couple of hours and
2. whether the relationship between ambient temperature and rate of core temperature change is different for patients who are or are not warmed with forced-air.
Eligibility Criteria
Inclusion Criteria
- Adults scheduled for major open thoracic surgery or video assist thoracic surgery or major abdominal surgery under general anesthesia expected to last at least two hours
Exclusion Criteria
- Special risk for bleeding or myocardial infarction (as determined by the attending anesthesiologist)
- Patients who would otherwise have been actively warmed
