Abstract
To prevent perioperative hypothermia, forced air warming blanket was compared with a passive insulation suit. Prospective, open, randomized controlled trial. Thirty patients were scheduled for orthopedic spinal surgery. The intervention group (group TS) received the thermal suit T-Balance before premedication and throughout the perioperative period, whereas the control group (group C) received forced air warming (FAW) during surgery. No statistically significant difference (ns) was found between the groups for core temperature 30minutes after induction of general anesthesia. Perioperative hypothermia occurred in 10 (66.7%) patients in group TS and 6 (40%) in group C (ns). For hypothermic patients, re-establishment of normothermia took significantly longer in group TS, mean 108±111minutes, than in group C, 33±59.5minutes (P=.03). The thermal suit did not prevent hypothermia in this study. FAW was significantly more efficient in re-establishing normothermia.
