[FRONTAL, AXILLARY AND TYMPANIC TEMPERATURE MEASUREMENTS IN CHILDREN]
Abstract:
The purpose of this study was to compare the results of body temperature measurements obtained by standard axillary thermometers with the results of infrared tympanic and frontal skin thermometry in afebrile children. This study comprises a single-center, prospective comparison trial. A total of 345 afebrile children aged 4 to 16 years hospitalized in the pediatric surgery department for elective surgery were included. One thousand axillary, tympanic and frontal measurements were obtained and compared. We used two different infrared thermometers in this study; one type measured the tympanic temperature, the other the temperature on the forehead. The axillary temperature measured with the glass thermometer was set as the standard. Each patient was exposed to a constant environmental temperature for a minimum of 10 min before simultaneous temperature measurements. The mean-frontal temperature 36.9 ± 0.38 °C was equal to the axillary temperature 36.9 ± 0.16 °C. The mean tympanic temperature was 36.3 ± 0.98 °C. The mean difference between the tympanic and axillary temperatures was -0.4 °C. The tympanic temperature had a threefold greater dispersion than frontal and a fivefold greater dispersion than axillary temperature. The results of this study suggest that the axillary temperature measured with glass thermometer has the least dispersion. Somewhat less reliable is the frontal temperature measured with infrared thermometer. The least reliable is tympanic temperature measurement.

Equipments Used to Measure Body Temperature
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,...
