Comparative Study Clinical Trial Controlled Clinical TrialComparison of a tympanic thermometer to rectal and oral thermometers in a pediatric emergency department.
We performed a clinical trial of a new tympanic thermometer to test its accuracy in a pediatric emergency department. Tympanic temperature was compared to oral or rectal glass and electronic temperature, depending on the developmental age of the child. ⋯ Our results suggest good correlation of tympanic with oral and rectal glass thermometry except in infants less than three months of age. Sensitivity and specificity, respectively, were 80% and 93% for detecting fever of 38 degrees C and 80% and 95% for detecting fever of 38.5 degrees C.

Comparative StudyComparison of pulmonary artery, rectal, and tympanic membrane temperatures in adult intensive care unit patients.
Tympanic thermometry using infrared thermography technology offers a noninvasive, rapid temperature measurement tool which may be useful for selected intensive care unit (ICU) patients. Multiple comparisons of pulmonary artery catheter (PAC), rectal (R), and tympanic membrane (TM) temperatures were performed in nine adult ICU patients using PAC temperatures as the gold standard. ⋯ Differences between either R (+0.4 degrees C) or TM (-0.1 degrees C) and PAC temperatures were consistent over selected ranges between 35 degrees C and 40 degrees C. The performance of TM and R was similar in the ability to predict PAC temperatures.
