The goals of this study were to evaluate whether touch can identify a warm nose as opposed to a cold nose, to examine the correlation between thermographically measured nose temperatures and rectal temperatures, and to calculate the accuracy of tactile assessment of nose temperature in detecting rectal hyperthermia and hypothermia in dogs. A total of 100 dogs presenting to an emergency room was prospectively enrolled. Tactile nose assessment was carried out on triage. Noses were subjectively categorized as warm, cold, or intermediate (neither warm nor cold). Thermographic nose temperatures were recorded using a thermal imaging camera. Tactile assessment categorized noses as warm, intermediate, or cold ( < 0.01). There was no correlation between thermographically measured nose temperature and rectal temperature ( = 0.02). Tactile assessment of noses as warm had a sensitivity of 29.4% and a specificity of 79.5% for detecting rectal hyperthermia; calculated test accuracy was 71%. Tactile assessment of noses as cold had a sensitivity of 54.5% and a specificity of 62.9%; calculated test accuracy was 62%. It was concluded that nose temperatures do not correlate with rectal temperatures. Tactile assessment of nose temperature is inaccurate for identifying rectal hyperthermia or hypothermia.
本研究旨在评估触觉是否能识别温暖的鼻子与寒冷的鼻子，检验通过热成像仪测量的鼻温与直肠温度之间的相关性，并计算触觉评估犬只鼻子温度以发现直肠高温或低温的准确率。共有 100 只急诊就诊的犬只被前瞻性纳入研究。在分诊时进行触觉鼻部评估。鼻子被主观地归类为温暖、寒冷或中间（既不温暖也不寒冷）。使用热成像摄像机记录鼻部的温度。触觉评估将鼻子分为温暖、中间或寒冷（<0.01）。通过热成像仪测量的鼻温与直肠温度之间无相关性（=0.02）。触觉评估将鼻子归类为温暖时，检测直肠高温的敏感度为 29.4%，特异性为 79.5%；计算出的检测准确率为 71%。将鼻子归类为寒冷时，敏感度为 54.5%，特异性为 62.9%；计算出的检测准确率为 62%。研究结论认为，鼻温与直肠温度不相关。触觉评估鼻子温度无法准确识别直肠高温或低温。
