Clinical Trial Summary

Unintentional perioperative hypothermia is a common occurrence. One of the recommendations of the guidelines to prevent hypothermia is the use of active warmers. It is known that low-flow anesthesia protects from hypothermia compared to high-flow anesthesia. In this study, we aimed to compare the efficacy of using active air blown heater and resistive heater in preventing hypothermia in patients with low flow and high flow inhalation anesthesia

ABSTRACT

PROSPECTIVE COMPARISON OF ACTIVE AIR BLOWN HEATER AND RESISTIVE TYPE HEATERS FOR PREVENTION OF HYPOTHERMIA IN HIGH CURRENT AND LOW CURRENT INHALATION ANESTHESIA

Aim: Unintentional perioperative hypothermia is a common occurrence. One of the recommendations of the guidelines to prevent hypothermia is the use of active warmers. It is known that low-flow anesthesia protects from hypothermia compared to high-flow anesthesia. In this study, we aimed to compare the efficacy of using active air blown heater and resistive heater in preventing hypothermia in patients with low flow and high flow inhalation anesthesia.

Materials and Methods: After ethics committee approval (Date: 08.12.2022/23), 112 patients with American Society of Anesthesiologist (ASA; American Society of Anesthesiologists) I-III, who were to undergo rhinoplasty between June 01, 2023 and January 01, 2024, were included in the study after informed consent was obtained. Group DA was defined as low flow anesthesia and active air blast heater, group DR as low flow anesthesia and resistive heater, group YA as high flow anesthesia and active air blast heater, and group YR as high flow anesthesia and resistive heater. Each group consisted of 28 patients. Heart rate, systolic, diastolic and mean arterial pressure, peripheral oxygen saturation values and body temperature values were measured and recorded at certain time intervals during the perioperative period and in the recovery unit. Body temperatures were also recorded in the ward. Thermal comfort scores were evaluated on admission, in the recovery unit and in the ward, while shivering score and patient satisfaction score were evaluated only in the recovery unit.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measurement of body temperatures in patients using two different body heaters during anesthesia applications.	In our study, two patient groups receiving high current and low current anesthesia will be heated with only one type of heater, either active air blowing heater or resistive heater, from the beginning of anesthesia. Their body temperatures will be measured and recorded throughout the operation.; In our study, COVIDIEN WarmTouch will be used as an active air blowing heater. INDITHERM Medical Alpha will be used as a resistive-type heater. Throughout the entire operation, body temperature will be monitored using the zero-heat flow method from the temporal artery to the body surface (3M Spot ON).	6 mounth
