To compare rectal and aural temperatures in canines presenting to a small animal emergency room.
We performed a prospective cohort study conducted between June 2022 and October 2022. One hundred and fifty-two dogs were evaluated that were presented to a private practice emergency room. Temperatures were obtained on presentation using both an aural Braun ExacTemp and a rectal Vet-Temp Rapid Digital Thermometer. The order of temperature measurement was randomized and recorded. Dogs were classified into three groups based on recorded temperature; normothermic (n = 105), hypothermic (n = 24), and hyperthermic (n = 23). Additional recorded parameters included: patient signalment, heart rate, respiratory rate, presence or absence of aural debris, coat length (classified as short, medium or long), body weight, body condition score, pain score, as well as venous lactate and non-invasive blood pressure, if performed.
The overall aural temperatures were significantly lower than rectal temperatures. The average rectal and aural temperatures were 38.7°C (range 36.6-40.7°C) and 38.3°C (range 35.7°C-40.4°C), respectively. Among all canines, there was a moderate, statistically significant relationship between rectal and aural temperatures (r = 0.636; p < 0.001) and this relationship remained significant with a weaker relationship for normothermic dogs (r = 0.411; p < 0.001). For hyperthermic and hypothermic dogs, there was not a statistically significant relationship between rectal and aural temperatures. Hyperthermic dogs had a significantly higher respiratory rate than other groups and hypothermic dogs were more likely to have a short haircoat. Lastly, ambient temperature, but not humidity, influenced patient temperature.
Our study found aural temperatures were consistently lower than rectal temperatures in dogs with both normal and abnormal rectal temperatures. Aural thermometry may not be an acceptable method of temperature measurement in the emergency patient cohort.
比较送至小动物急诊室的犬只的直肠温度和耳温。
我们于2022年6月至2022年10月进行了一项前瞻性队列研究。对送至一家私人诊所急诊室的152只犬进行了评估。使用耳温 Braun ExacTemp 和直肠 Vet-Temp Rapid Digital 温度计在犬只就诊时测量体温。温度测量顺序随机并记录。根据记录的体温将犬只分为三组：体温正常组（n = 105）、体温过低组（n = 24）和体温过高组（n = 23）。额外记录的参数包括：患犬的特征、心率、呼吸频率、耳部是否有异物、被毛长度（分为短、中或长）、体重、身体状况评分、疼痛评分，以及静脉血乳酸水平和无创血压（若进行了此项测量）。
总体耳温显著低于直肠温度。直肠温度和耳温的平均温度分别为38.7°C（范围36.6 - 40.7°C）和38.3°C（范围35.7°C - 40.4°C）。在所有犬只中，直肠温度和耳温之间存在中度的、具有统计学意义的相关性（r = 0.636；p < 0.001），对于体温正常的犬只，这种相关性较弱但仍具有统计学意义（r = 0.411；p < 0.001）。对于体温过高和体温过低的犬只，直肠温度和耳温之间不存在统计学意义的相关性。体温过高的犬只呼吸频率显著高于其他组，体温过低的犬只更可能有短被毛。最后，环境温度而非湿度会影响患犬体温。
我们的研究发现，无论是直肠温度正常还是异常的犬只，耳温始终低于直肠温度。在急诊患犬队列中，耳温测量可能不是一种可接受的体温测量方法。
