Comparison of Electric Heating Pad Versus Forced-air Warming to Prevent Inadvertent Perioperative Hypothermia

Comparison of Electric Heating Pad Versus Forced-air Warming to Prevent Inadvertent Perioperative Hypothermia: A Randomized Controlled Trial

Compare core body temperature after laparoscopic surgery using the forced air heating system versus the WARMTAC® (a carbon fiber electric blanket).

Study Overview

• Status: Recruiting
• Conditions: Hypothermia; Anesthesia; Temperature Change, Body
• Intervention / Treatment: Device: WARMTAC; Device: 3M Bair Hugger

Detailed Description

In order to prevent perioperative hypothermia, we will compare two different heating sistems, one of them is an electric pad made with carbon fiber and the other system is a forced-air blanket. Both of them will be situated under the patient during all the laparoscopic surgey.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Electrical heating pad; Electrical heating pad (WARMTAC device). Patients will be randomized to one arm. In this arm, the WARMTAC device will be conected and warmed to 41 degrees before patients lay down.	Device: WARMTAC; Randomization to one of the arms previous to surgery.
Experimental: forced-air warming device; Forced-air warming device (3M device). In this arm, the 3M blanket will be conected to forced-air machine and warmed to 41 degrees before patients lay down.	Device: 3M Bair Hugger; Randomization to one of the arms previous to surgery.
