Hypothermia Risk Prediction Combined With Active Insulation Management in Geriatric Surgery

First Affiliated Hospital of Chongqing Medical University1,360 enrolled

Overview

To evaluate the effectiveness and safety of hypothermia risk prediction combined with active warming management to reduce intraoperative hypothermia in elderly patients undergoing elective general anesthesia, improve the quality of anesthesia management, and enhance patients' awareness of the work of anesthesiologists.

Hypothermia; Anesthesia Body Temperature Changes

Interventions

IOB Warming Unit (WU505) + Inflatable Warming BlanketDEVICE

The inflatable warming method (Inflatable Warming Unit (IOB Warming Unit, WU505) + Inflatable Warming Blanket (IOB Warming Blanket)) is a common clinical warming technique in anesthesiology, which is well tolerated by patients and safe and effective. The anesthesiology department has established standard operating procedures for the above-mentioned non-invasive operations.

Outcomes

Primary Outcomes

Incidence of intraoperative hypothermia

Intraoperative hypothermia, defined as a core temperature below 36 °C

Time frame: Up to 24 hours, from the time of entry into the operating room to the time of exit from the operating room.

Secondary Outcomes

Postprocedural Shivering

A compensatory response of the body to hypothermic stimuli that cause rapid rhythmic，Once the procedure is completed, the patient will be extubated and the presence or absence of shivering will be recorded up to 60 minutes after the extubation with the Badjatia 2008 scale consisting of a gradual evaluation of 0 to 3 points. With scores greater or equal to 1, shivering is considered established. contraction of skeletal muscle for thermogenesis

Time frame: up to 60 minutes

Intraoperative bleeding volume

Routine intraoperative monitoring indicators

Time frame: up to 24 hours after surgery

Postoperative blood count

The number of red blood cells, white blood cells and platelets in the blood is calculated by smearing the blood in a routine blood test and looking at it under the microscope.

Time frame: up to 24 hours after surgery

30-day postoperative readmission

Routine postoperative monitoring indicators

Time frame: 30 days after surgery

6-month postoperative complications (surgical complications, pulmonary infections, blood clots)

Routine postoperative monitoring indicators

Time frame: 6 months after surgery

30-day postoperative complications (surgical complications, pulmonary infections, blood clots)
