INTRODUCTION
RESULTS
Perioperative hypothermia is associated with a variety of complications Surgical site infections (SSI), patient’s discomfort and increased hospital length of stay (LOS) [1] Despite effective intraoperative warming techniques, induction of general anesthesia inevitably results in a reduction of core body temperature [2] Preoperative warming has been shown to reduce time spent hypothermic intraoperatively [3,4]
Patient sample: n=200 participants analyzed. No significant differences in baseline demographic data including gender, age, BMI, and temperature between groups. Effect of prewarming with the Bair Paws system: Reduced intraoperative hypothermia
STUDY AIM
46 prewarmed participants (46.5%) were hypothermic vs 64 control participants (63.4%) (p = 0.023) 45 min after induction (end of heat redistribution) the mean temperature for the prewarmed group is 0.26˚C higher (95%CI: 0.045-0.55˚C, p = 0.0008) AUC is 0.65˚C∙min higher in prewarmed participants (95%CI: 0.01-2.25˚C∙min, p = 0.004) Delay between the end of preoperative warming and initiation of intraoperative warming changes the AUC for prewarmed participants (p
