Intervention / Comparator Agent
|
Type |
Name |
Details |
Comparator Agent |
cowarming |
Full body (except the face) convective warming will be started as soon as the patient is shifted into the operating room (Equator convective body warmer set to a output of 45°c). Only then monitoring will be established, intravenous access will be secured and induction of anesthesia will begin. Warming continues into the intraoperative period over the available body surface area. |
Intervention |
Prewarming |
patients are prewarmed for one hour before the induction of anesthesia in the preoperative holding area using Equator convective body warmer and full body warming blanket covering all the body parts except the face. Patients will be prewarmed with temperature output of the warming unit set to 45°c for 60 min. Warming will continue during induction of anesthesia and the surgery. |

Brief Summary
|
In this open label study two techniques of patient warming ( prewarming - convective warming beginning 1 hour before induction of anesthesia and extending into intraoperative period; cowarming - convective warming beginning with induction of anesthesia and extending into intraoperative period) will be compared to prevent intraoperative hypothermia. Included patients (approximately 60 in number) will undergo matched randomization (matched with respect to the type of surgery) to group prewarming where patients are warmed with convective warmer 1 hour prior to anesthesia and group cowarming where the convective warming begins along with the induction of general anesthesia. In both the groups warming continues into the intraoperative period till the end of the surgery. The primary outcome measure is the nasopharyngeal body temperature measured starting from induction of anesthesia, every 15 min till the end of the surgery. The secondary outcome measures are the axillary temperature measured starting from induction of anesthesia every 15 min till the end of surgery, patient comfort during prewarming in group prewarming, incidence of shivering during the first postoperative hour. |
