将家兔和狗暴露于热环境,使动物肛温升至42.5℃(家兔)和43.0℃(狗)。实验动物分成4组,正常对照组(室温20～25℃),过热对照组(不治疗),输液对照组(静脉输32±0.3℃生理盐水)和输冷液组(家兔和狗分别静脉输1.2±0.34℃和2.0±0.1℃生理盐水)。实验结果表明,肛温的最大下降值,输冷液兔组为2.43℃,输冷液狗组为2.81℃,输液对照兔组为0.5℃,过热对照兔组肛温不下降,过热对照狗组下降1.1℃。输冷液动物的活存率显著比过热对照组和输液对照高。热损伤病理改变,输冷液组显著比过热对照组和输液对照组轻。
The rabbits and dogs were exposed to a hot environment and the animal’s rectal temperature rose to 42.5 ° C (rabbit) and 43.0 ° C (dog). The experimental animals were divided into 4 groups: normal control group (room temperature 20-25 ℃), overheated control group (untreated group), infusion control group (32 ± 0.3 ℃ saline intravenously) and infusion solution group Lose 1.2 ± 0.34 ℃ and 2.0 ± 0.1 ℃ saline). The experimental results showed that the maximum value of rectal temperature was 2.43 ℃ in the transfusion group and 2.81 ℃ in the transfusion group and 0.5 ℃ in the transfusion group. The rectal temperature did not decrease in the control group and the overheated control group Down 1.1 ℃. The survival rate of animals with cold-blooded animals was significantly higher than that of the overheated control group and the infusion controls. Pathological changes of heat injury, heat transfusion group was significantly lighter than the control group and the infusion of heat.
