Resistive-Heating or Forced-Air Warming for the Prevention of Redistribution Hypothermia

Abstract

Prewarming should be considered part of the anesthetic management when patients are at risk for postoperative hypothermia.

Conductive warming and insulation reduces perioperative hypothermia

“…Redistribution of body heat from the core to the periphery was unusually small in this study and similar In most clinical studies, the redistribution of heat after the induction of anaesthesia leads to a reduction in core temperature of about 0.3°C to 0.8°C [9][10][11][12] in the first hour, whereas under experimental conditions it can reach up to 1.7°C [13]. This small decrease in core temperature may be explained by the fact that patients were kept comfortably warm during the entire preoperative period (i.e., from the ward, during transport to the operating theatre and at the induction of anaesthesia) with the same effective insulating hospital blanket as was used during the operation.…”

Peri‐operative warming devices: performance and clinical application

“…peri-operative core temperatures between patients pre-warmed through resistive heating [102] but not forced-air warming when compared with controls [103,104]. Furthermore, an earlier study assessing the clinical impact of extending peri-operative conductive warming during abdominal surgery has also shown that the mattresses are well tolerated and that pre-and postoperative conductive warming significantly reduces blood loss and complication rates [105].…”

Preoperative forced-air warming combined with intraoperative warming versus intraoperative warming alone in the prevention of hypothermia during intraabdominal surgery.

“…Hastaların preoperatif ısıtılması gerektiği ve preoperatif dönemde ısıtmanın anestezi yönetiminin bir parçası olduğu De Witte JL ve ark. (8) tarafından önemle vurgulanmıştır. Çalışmamızda da hastalar preoperatif dönemde 30 dk.…”
