Abstract

Objective: To evaluate different methods of monitoring body temperature in anesthetized dogs with comparison to core temperature obtained via esophageal probe.

Methods: Client-owned dogs undergoing general anesthesia for various procedures were included in this observational study. The temperature was taken sequentially every 10 minutes from the rectum, axilla, and nasal cavity with a digital thermistor thermometer, and compared to esophageal core temperature via paired t-tests. Differences from the gold standard esophageal temperature were assessed via Bland-Altman plots and further evaluated for factors like time under anesthesia and presence of Hypo-/Normo- or Hyperthermia. In addition, it was analyzed whether a correction factor for peripheral measurement sites (nasal cavity and axilla) would be applicable in a reliable representation of the body temperature. The level of significance in all tests was set at p<0.05.

Results: In this study, 95 simultaneous temperature measurements at the 4 different sites were obtained from 30 dogs. Mean difference and limits of agreement from esophageal temperature for the different measurement methods were 0.0±0.72°C for rectal temperature, -1.2±1.42°C for axillary and -1.0±2.02°C for nasal temperature. Axillary and nasal temperatures were not significantly different (p=0.5721 and p=0.9287, respectively) from esophageal temperature with a +1.2°C and +1°C correction factor, respectively.

Conclusion and clinical relevance: During perioperative temperature measurement in anesthetized patients, rectal and esophageal measurements can be used interchangeable. However, if these are not available, the use of axillary or nasal sites is only reliable after applying a correction factor.

麻醉犬的体温测量——鼻、腋、直肠和食管温度的比较。

目的:探讨麻醉犬体温监测的不同方法，并与食管探头测得的核心体温进行比较。方法:客户拥有的狗接受全身麻醉的各种程序包括在这个观察性研究。用数字热敏电阻温度计每10分钟依次测量一次直肠、腋窝和鼻腔的温度，并通过配对t检验与食管核心温度进行比较。通过Bland-Altman图评估与金标准食管温度的差异，并进一步评估麻醉时间和低/正常或高温的存在等因素。此外，还分析了周围测量部位(鼻腔和腋窝)的校正因子是否适用于可靠的体温表示。结果:在本研究中，从30只狗的4个不同部位同时获得95个温度测量值。不同测量方法的食道温度平均差值和一致限分别为:直肠温度0.0±0.72°C，腋窝温度-1.2±1.42°C，鼻温度-1.0±2.02°C。腋窝和鼻腔温度与+1.2°C和+1°C校正因子下的食管温度差异无统计学意义(p=0.5721和p=0.9287)。结论及临床意义:在麻醉患者围术期体温测量中，直肠和食管温度测量可互换使用。然而，如果这些都不可用，使用腋窝或鼻腔部位是唯一可靠的应用校正因子后。

期刊介绍： Die Tierärztliche Praxis wendet sich mit ihren beiden Reihen als einzige veterinärmedizinische Fachzeitschrift explizit an den Großtier- bzw. Kleintierpraktiker und garantiert damit eine zielgruppengenaue Ansprache. Für den Spezialisten bietet sie Original- oder Übersichtsartikel zu neuen Therapie- und Operationsverfahren oder den Einsatz moderner bildgebender Verfahren. Der weniger spezialisierte Tierarzt oder Berufseinsteiger findet auf seinen Berufsalltag zugeschnittene praxisbezogene Beiträge in der Fortbildungsrubrik „Aus Studium und Praxis“. Mit dem hervorgehobenen „Fazit für die Praxis“ am Ende jedes Artikels verschafft sich auch der eilige Leser einen raschen Überblick über die wichtigsten Inhalte dieser modern konzipierten Fachzeitschrift mit den vielen hochwertigen, überwiegend farbigen Abbildungen. In jedem Heft ermöglicht ein ATF-anerkannter Fortbildungsartikel den Erwerb einer ATF-Stunde (Akademie für tierärztliche Fortbildung).
