Zero Heat Flux Thermometry System Comparison Trial
3M(TM)SpotOn(TM) Temperature Monitoring System Thermometry Trial
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.

Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
  • Body Temperature
  • Thermosensing
  • Temperature
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 Name: 3M(TM) SpotOn(TM) temperature monitoring system
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.
Intervention: Device: Zero-heat-flux thermometry
