A433 forced air warming minimizes Hypothermia during Orthotopic liver Transplantation

Patient temperature: An introduction to the clinical guideline for the prevention of unplanned perioperative hypothermia

“…1,7 Contributing factors vary and may increase the risk for hypothermia in the surgical patient. Contributing risk factors include the following [1][2][3][4][5][6][7][8] :…”

“…10 • Assess for other signs and symptoms of hypothermia (shivering, piloerection, and/or cold extremities Active warming is the application of a forced air convection warming system. 3,4,5,11,33,34,35,36,40 Apply appropriate passive insulation and increase the ambient room temperature (minimum 20°C-24°C or 68°F-75°F.) 1,39 Consider warmed IV fluids.…”

Warming With a Forced Air Warming Blanket Minimizes Anesthetic‐Induced Hypothermia in Cats

“…These results compare favorably with findings reported in human patients warmed with the BH forced‐air warming system. In people undergoing orthotopic liver transplantation, 27 distal esophageal temperatures by the completion of surgery were significantly higher in patients receiving forced‐air warming than in control patients receiving standard methods of thermal support (35.6°± 0.2°C compared to 34.7°± 0.2°C, respectively). In a second study, 29 the forced‐air warming system was shown to not only prevent heat losses but to actually warm adult patients undergoing spinal surgery, with patients displaying a net heat gain of 0.6°C.…”

“…Part of the success of forced‐air warming in minimizing intraoperative hypothermia in anesthetized people may lie in the use of additional, aggressive means of patient thermal support. Reports documenting the success of the forced‐air warming technique have always combined the patient warming system with other forms of temperature control, including warming and humidification of inspired gases, the use of low fresh‐gas flow rates, warming all intravenous fluids and blood products to body temperature, and warming the operating room 27,29 . Previous reports assessing the efficacy of different methods of temperature control in anesthetized cats 21 and dogs 22 have also shown the benefit of combining various patient warming techniques.…”

“…Because most metabolic heat is lost through the skin, investigators proposed that intraoperative hypothermia could be minimized by reducing cutaneous heat loss 1 . The Bair Hugger patient warming system has been shown to successfully minimize decreases in body temperature during abdominal surgery, 27 and to significantly aid in the rewarming of hypothermic patients in the postoperative recovery unit 10 …”
