The Effects of Ambient Temperature and Forced-air Warming on Intraoperative Core Temperature
In Brief
A clinical study evaluating Ambient Temperature 19°C, Ambient Temperature 21°C, and 3 other interventions for Major Surgery Under General Anesthesia. Completed, enrolled 292 participants across 1 site.
Detailed 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.

Patients assigned to forced-air warming will also be covered with a gown and surgical drapes, but a forced-air cover (Bair hugger 63500, 3M) will be inserted between the gown and the skin surface.
Patients assigned to passive insulation will be covered as usual with a cotton gown and single layer of cloth surgical draping.
