To compare infrared thermometry with rectal thermometry as a method of assessing core body temperature in dogs and to assess the effect of otitis externa on external ear canal temperature (EECT).
Prospective study.
650 dogs without history or clinical signs of otitis externa and 85 dogs with recurrent or chronic otitis externa.
Rectal temperature was measured, using a mercury thermometer. External ear canal temperature was measured, using an infrared tympanic thermometer.
Measurements of body temperature at the 2 sites did not agree. Sensitivity and specificity of infrared thermometry in detecting fever, as determined by rectal thermometry, were 69.7 and 84.6%, respectively. Use of methods to predict rectal temperature from EECT did not improve the accuracy of infrared thermometry. Otitis externa significantly influenced EECT.
Use of infrared thermometry as a replacement for rectal thermometry in assessing core body temperature in dogs was unsatisfactory. The 2 methods for measuring body temperature were not interchangeable in dogs.
比较红外测温法与直肠测温法作为评估犬核心体温的方法，并评估外耳道炎对外耳道温度（EECT）的影响。
前瞻性研究。
650只无外耳道炎病史或临床症状的犬以及85只复发性或慢性外耳道炎犬。
使用水银温度计测量直肠温度。使用红外鼓膜温度计测量外耳道温度。
两个部位的体温测量结果不一致。通过直肠测温法确定，红外测温法检测发热的敏感性和特异性分别为69.7%和84.6%。使用从EECT预测直肠温度的方法并未提高红外测温法的准确性。外耳道炎显著影响EECT。
在评估犬的核心体温时，使用红外测温法替代直肠测温法并不理想。两种测量体温的方法在犬中不可互换。
