The Comparison of Warming Techniques in Patients Undergoing Open Abdominal Surgery in Litotomy Position

The patients scheduled to undergo major abdominal surgery in litotomy position will be randomized into two groups in order to compare the effects of two warming techniques during the intraoperative period.

The patients will be randomized into two groups. All patients will receive prewarming with forced-air warming device for 30 minutes. All patients will receive warmed fluids during intraoperative period. One group will receive warming with only forced-air warming device and the other group will receive warming with both forced-air warming device and water mattress. Timpanic, esophageal and peripheral temperature monitoring will be performed.
