Summary

This study evaluates the effect of active prewarming on the frequency and duration of perioperative hypothermia. 50% of patients will receive active warming with forced-air devices prior to entering the operating room, and the other 50% will not receive any active heating measures.

Detailed description

Inadvertent perioperative hypothermia is defined as a body temperature below 36º C during the perioperative period. It occurs as a result of the effects of anesthetic drugs on the regulation of body temperature and exposure to a cold environment. The main temperature loss during the perioperative period occurs during the first hour after the anesthetic induction as a result of heat redistribution from the central compartment to the peripheral compartment The most effective strategy to prevent perioperative hypothermia is the use of forced-air warming devices. These devices are usually initiated once the patient enters the operating room. At that time, the patient has already initiated the heat loss by distributing heat from the central to the peripheral compartment to maintain body temperature. We intend to use forced-air warming devices before the patients is transferred to the operating room in order to preserve the peripheral body temperature. This way the redistribution of heat should be avoided and, therefore, perioperative hypothermia and its harmful effects will be prevented.

Conditions

• Hypothermia; Anesthesia
• Hypothermia Due to Anesthetic
• Hypothermia Following Anesthesia
• Hypothermia Following Anesthesia, Sequela

Interventions

Type	Name	Description
DEVICE	Forced air warming devices	In the treatment group, heating will be started with a pre-surgical forced-air blanket "Outpatient Warming Blanket model 11101 Bair Hugger from 3M" and a forced-air heating unit "Bair Hugger Warming Unit Model 775 from 3M" at 38-43º C which will be maintain during the stay in the pre-surgery room until the transfer to the operating room
