Zero Heat Flux Thermometry System Comparison Trial

September 1, 2020 updated by: 3M

3M(TM)SpotOn(TM) Temperature Monitoring System Thermometry Trial

Nasopharyngeal and deep tissue temperatures will be measured simultaneously during surgery and compared for agreement. The hypothesis of this trial is that deep tissue temperature as measured by zero-heat-flux thermometry will agree with nasopharyngeal temperatures during surgery.

Detailed Description

The core temperature of the body normally decreases in response to anesthesia. Deep tissue temperature can be used to estimate of body core temperature. Deep tissue temperature of the forehead will be measured using a new technology known as zero-heat-flux thermometry. The usual way to measure internal body temperature is within the nasal cavity (nasopharyngeal temperature). Nasopharyngeal and deep tissue temperatures will be measured simultaneously during surgery and compared for agreement. The hypothesis of this trial is that deep tissue temperature as measured by zero-heat-flux thermometry will agree with nasopharyngeal temperatures during surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Zero-Heat-Flux
This is a single arm study. All patients will have deep tissue temperature monitored from the nasopharyngeal and lateral forehead sites simultaneously.
Device: Zero-heat-flux thermometry
The zero-heat-flux thermometer will be placed on the subject's lateral forehead for the duration of the surgery to measure deep tissue temperature.
Other Names:
  • 3M(TM) SpotOn(TM) temperature monitoring system

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Body Temperature Difference in Degrees Celsius
Time Frame: Every 5 to 10 minutes, or as clinically indicated, for the duration of the surgery from the time of incision to the time of closure. The average duration of surgery was 57 minutes.
Body temperature difference as defined by Agreement (bias - Zero heat flux thermometry minus nasopharyngeal) between simultaneously-acquired nasopharyngeal and forehead deep tissue temperatures as assessed by Bland and Altman repeated measures technique.
Every 5 to 10 minutes, or as clinically indicated, for the duration of the surgery from the time of incision to the time of closure. The average duration of surgery was 57 minutes.
