摘要
Objective-To compare rectal versus axillary temperatures in dogs and cats. Design-Prospective observational study. Animals-94 dogs and 31 cats. Procedures-Paired axillary and rectal temperatures were measured in random order with a standardized method. Animal signalment, initial complaint, blood pressure, blood lactate concentration, and variables associated with vascular perfusion and coat were evaluated for associations with axillary and rectal temperatures. Results-Axillary temperature was positively correlated with rectal temperature (rho = 0.75 in both species). Median axillary temperature (38.4 degrees C [101.1 degrees F] in dogs, and 38.4 degrees C [101.2 degrees F] in cats) was significantly different from median rectal temperature in dogs (38.9 degrees C [102.0 degrees F]) but not in cats (38.6 degrees C [101.5 degrees F]). Median rectal-axillary gradient (difference) was 0.4 degrees C (0.7 degrees F; range, -1.3 degrees to 2.3 degrees C [-2.4 degrees to 4.1 degrees F]) in dogs and 0.17 degrees C (0.3 degrees F; range -1.1 degrees to 1.6 degrees C [-1.9 degrees to 3 degrees F]) in cats. Sensitivity and specificity for detection of hyperthermia with axillary temperature were 57% and 100%, respectively, in dogs and 33% and 100%, respectively, in cats; sensitivity and specificity for detection of hypothermia were 86% and 87%, respectively, in dogs and 80% and 96%, respectively, in cats. Body weight (rho = 0.514) and body condition score (rho = 0.431) were correlated with rectal-axillary gradient in cats. Conclusions and Clinical Relevance-Although axillary and rectal temperatures were correlated in dogs and cats, a large gradient was present between rectal temperature and axillary temperature, suggesting that axillary temperature should not be used as a substitute for rectal temperature.
