The Effect of Preoperative Patient Warming in the Prevention of Perioperative Hypothermia in Major Abdominal Surgery Under Combined General/Epidural Anaesthesia
In Brief
A clinical study evaluating Forced-air warming for Preoperative Warming and 5 related conditions. Completed, enrolled 99 participants across 2 sites.
Detailed Summary
The study should evaluate how long patients undergoing major abdominal surgery under combined general/epidural anaesthesia have to be actively warmed preoperatively to prevent perioperative hypothermia and postoperative shivering. 99 patients will receive forced-air skin-surface warming for different duration. Body temperature will be measured at the tympanic membrane. The investigators hypothesize that active warming before starting the epidural anaesthesia will decrease the incidence of perioperative hypothermia.

Timeline
Interventions
In the intervention groups a forced-air cover (Level 1 Snuggle Warm Upper Body Blanket, Smiths Medicals) will be positioned over the patients sitting or laying on the operating table for 15 min before start of epidural anaesthesia and afterwards till start of general anaesthesia (group 3), for 15 min before start of general anaesthesia (group 2) or only after induction of general anaesthesia (group 1, control). All patients will receive forced-air warming after induction of general anaesthesia till end of surgery.
