Active thermal devices are used to prevent hypothermia during anaesthetic procedures. Two thermal devices, one conductive and one convective, were compared for their effect on maintenance of core body temperature (CBT) during 1h of general anaesthesia in pigeons (Columba livia domestica). In a randomised crossover trial, CBT decreased significantly less with the conductive device than when the convective device was used (2.5 ± 0.7°C and 3.8 ± 0.9°C, respectively; P<0.01). Moreover, CBT was maintained above a clinically acceptable level of 38.3°C in 82% of pigeons when the conductive device was selected, compared to 14% of pigeons with the convective device. The use of the conductive device is therefore recommended in preference to the convective device when performing anaesthetic procedures in birds.
主动式保暖设备用于预防麻醉过程中的体温过低。本研究比较了两种热设备（一种传导式，一种对流式）在鸽子（Columba livia domestica）全身麻醉 1 小时期间对核心体温（CBT）维持的影响。在一项随机交叉试验中，与使用对流式设备相比，传导式设备使 CBT 显著降低（分别为 2.5±0.7°C 和 3.8±0.9°C；P<0.01）。此外，当选择传导式设备时，82%的鸽子的 CBT 维持在临床可接受的 38.3°C以上，而使用对流式设备时，只有 14%的鸽子的 CBT 维持在临床可接受的水平。因此，在鸟类进行麻醉程序时，建议优先使用传导式设备，而不是对流式设备。
