Official Title: Accuracy of Temperature Measurement in Post-Anesthesia Care Units

Further study details as provided by Outcomes Research Consortium:

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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

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
