High-Flow Oxygen Preserve Intraoperative Body Temperature

Background: Hypothermia would increase the risk of bleeding, infection, cardiac complications and delay recovery. The transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) could not only provide the larger oxygen preserve but also humidified high flow. However, Objectives: We wanted to investigated whether the humidified high flow of THRIVE would affect perioperative body temperature (BT). Patients and methods: We reviewed the medical records of adult patients undergoing non-intubated video-assisted thoracic surgery (NIVATS) have been retrospective reviewed. All patients have received force air warming. Multiple linear regression analysis was used to determine which factors were associated with BT loss. Expected result: In patients receiving NIVATS under force air warming, the use of THRIVE may provide more efficiently BT preserve, although the patients with oxygen mask could have acceptable BT preservation. The more BT loss is associated with the advanced age and higher BMI level. The anesthetic duration is not associated with the BT loss.
