Resistive Versus Forced-Air Warming for Prevention of Perioperative Hypothermia
Sponsor: Masarykova Nemocnice v Usti nad Labem, Krajska Zdravotni a.s.
Summary
Perioperative hypothermia (core temperature below 36.0 °C) is a common complication of surgery and is associated with increased blood loss, wound infection, cardiovascular events and patient discomfort. Forced-air warming (Bair Hugger) is the standard method of active warming. Resistive conductive warming (HotDog) transfers heat by direct contact and does not blow air into the operating room, which may be advantageous. This randomised trial will test whether resistive warming is not inferior to forced-air warming in preventing hypothermia on arrival in the post-anaesthesia care unit (PACU) in adults undergoing elective surgery under general anaesthesia.

Interventions
Forced-air warming
Convective active warming system blowing warmed air through a disposable upper- or lower-body blanket (Bair Hugger, Solventum, formerly 3M), set to 43 °C, from induction of anaesthesia until the end of surgery.
Resistive conductive warming
Air-free resistive polymer warming mattress placed under the patient, transferring heat by direct contact (HotDog, Augustine Surgical), set to 42 °C, from induction of anaesthesia until the end of surgery.
