    Abstract:
    To determine if a tympanic membrane thermometer is of benefit on a pediatric unit. Temperature readings using a tympanic membrane thermometer and an electronic thermometer were compared for 295 paired observations. The electronic temperature readings were done by rectal (n = 32), oral (n = 65), and axillary (n = 198) routes. Differences in tympanic and electronic readings were compared by paired t-tests, and the readings were also correlated. The nursing time in seconds was also compared between electronic and tympanic measurements. Parents and nurses rated their opinion of each type of measurement on a 0-5 Likert scale. Nurses rated the patient's response using the same scale. Results indicate that temperature readings differ by an average of .2- .5 degree between tympanic and electronic thermometers. Correlations are statistically significant but of low-to-moderate strength. Parents and nurses did not rate the types of instruments differently. The nurses rated the electronic axillary method as being more acceptable to toddlers. The tympanic membrane measurement took an average of 30-38 seconds less time to take. Tympanic membrane thermometry saves nursing time. Although the correlations were not strong between electronic and tympanic membrane measurements, the tympanic reading was closer to the electronic rectal reading than to axillary or oral readings.
