摘　　要：目的探讨湿热、创伤复合因素作用下,静脉滴注低温生理盐水对家兔直肠温度(Tr)变化的影响,从而明确湿热创伤复合因素作用下静脉滴注低温生理盐水的降温效果。方法按施加的输液温度将24只新西兰家兔随机分为无创常温输液组、有创常温输液组、无创低温输液组、有创低温输液组,每组6只。各组均暴露在高温高湿环境中120 m in。创伤组家兔致粉碎性骨折。湿热暴露60 m in后,低温输液组静脉滴注(4±1)℃低温盐水,常温输液组滴注(23±1)℃生理盐水。监测直肠温度变化,并每20 m in记录1次。结果无创低温输液组和有创低温输液组湿热暴露后20～60 m in时,Tr升高与无创常温输液组和有创常温输液组相似,但70～120 m in时,Tr开始下降,低温输液组与常温输液组间Tr值变化有显著性差异(P<0.01)。结论热暴露后,家兔不论是否有创伤,均可出现Tr持续上升,静脉滴注低温生理盐水可使家兔的Tr得到了良好的控制,避免了过高热对机体重要器官的不可逆损害。Objective To investigate the effects of the intravenous hypothermie transfusion therapy on rectal temperature of wounded rabbits in hot and humid environment so as to make sure the cooling effect of the intravenous hypothermic transfusion therapy on rab- bit under the condition of trauma and hot, humid environment. Methods The experimental rabbits （n=24） were divided into 4 groups. Each group （n=6） exposed in hot and humid condition for 120 minutes. Normal saline solution group （HNN）： fluid temperature （23±1）℃. Hypothermic normal saline solution group （HBN）： fluid temperature （4-1）℃. The rectal temperature （Tr） was record by the biological recorder every 20 min. Results Tr raised directly in all group at 20-60 min after hot exposed, but began to drop at from 70 to 120 min in Group HNN and HBN, and there was significant difference between hypothermic normal saline solution groups and normal saline solution groups （P〈0.01）. Conclusion Without reference to trauma, Tr raised gradually and significantly in all groups after hot exposed. Intravenous hypothermic transfusion therapy makes it possible that core heat of body convert, eradiate and conduct by arterial-venous difference in temperature. Tr of wounded rabbits under hot and humid environment were well controlled by intravenous hvoothermic transfusion theraoy.
