We have evaluated the efficacy of the delayed forced air warming during
abdominal aortic surgery in 18 patients. Patients were allocated randomly
to one of two groups: the control group (n = 9) received no intraoperative
warming device; the Bair-Hugger group (n = 9) had active skin surface
warming with an upper body cover. The device was activated when core
temperature decreased to less than 36 degrees C. The reduction in core
temperature was 0.6 degrees C during the first hour after induction and 0.4
degrees C during the second hour in both groups. In the control group, core
temperature continued to decrease until the end of surgery, whereas in the
Bair-Hugger group, the reduction in core temperature stopped after 1 h of
warming, and then rewarming began. At the end of surgery, core temperature
in the Bair- Hugger group was similar to core temperature before induction,
and was higher than core temperature in the control group (P < 0.003).
