Further study details as provided by The Cleveland Clinic:

Primary Outcome Measures:
  • To determine the accuracy of various temperature-monitoring methods and sites suitable for Post Anesthesia Care Unit use. [ Time Frame: Discharge from Post Anesthesia Care Unit ]

Secondary Outcome Measures:
  • To quantify the core temperature changes that occur during transport from the Operating Room to the PostAnesthesia Care Unit. [ Time Frame: PostAnesthesia Care Unit ]

Enrollment: 50

  • 2. Bladder (Mon-a-therm, Tyco-Mallinckrodt Anesthesia Products,
  • 3. Infrared-aural canal bilaterally (GENIUS Model 3000A, Kendall Healthcare)

Detailed Description:

Several measurements of temperature will be taken at 30 minute intervals during surgery under general anesthesia and in the post operative care unit. Measurements will be taken as follows:

  • esophagus using an internal stethoscope
  • urinary bladder using a catheter
  • ear canal
  • skin of the forehead using adhesive devices(4 thermometers)
  • axilla ("armpit") using adhesive devices(2 thermometers)
  • mouth
  • skin of the upper chest
