Insights

Tympanic infrared thermometry is not sensitive enough for screening fever in children. However, it may help confirm fever when suspected by touch in primary care settings.

Area of Science:

  • Pediatrics
  • Primary Care Medicine
  • Medical Devices

Background:

  • Tympanic thermometry offers convenience in primary care.
  • Limited data exists comparing tympanic thermometry with traditional methods.
  • Accurate fever detection is crucial in pediatric primary care.

Purpose of the Study:

  • To compare the accuracy of tympanic infrared thermometry against axillary mercury thermometry in preschool children.
  • To evaluate tympanic thermometry's utility as a screening and diagnostic tool for fever in primary care.

Main Methods:

  • A study involving 94 preschool children with acute cough in UK primary care.
  • Comparison of tympanic infrared and axillary mercury thermometers.
  • Analysis of agreement, sensitivity, and specificity.

Main Results:

  • Tympanic infrared thermometry demonstrated poor agreement and low sensitivity.
  • High specificity was observed for tympanic infrared thermometry.
  • The device was found to be too insensitive for fever screening.

Conclusions:

  • Tympanic infrared thermometry is unsuitable as a standalone fever screening tool for children.
  • It may serve as a 'rule in' test for fever when clinical suspicion is already present.
  • Further research on accurate pediatric thermometry in primary care is warranted.

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
Temperature Measurement Sites01:14

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
Thermometers and Temperature Scales01:22

Thermometers and Temperature Scales

Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...
Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
