摘　　要：发热是临床上常见的症状,体温过高时会对机体产生不利的影响。当降温毯铺于患者的背部及臀部时,交感神经张力增加,导致皮肤血管收缩,阻止热量的散发,使中心体温上升,而并非使中心体温下降。此外,由于降温毯的低温可使患者产生寒颤反应,随后脂肪、碳水化合物和蛋白质代谢增加,热量产生将增加。因此,在临床使用中应加以注意。Fever is a common clinical symptom. Hyperpyrexia would have adverse effect on the body. When the cooling blanket is spread under the patient＇s back and hip, sympathetic nerve tension increases. It can cause skin vasoconstriction and prevent heat loss. As a result, the core body temperature would rise rather than decrease. In addition, due to the low temperature of cooling blanket, the patient may have chills. Consequently, the fat, carbohydrates and protein metabolism increase, and more heat would be produced. Therefore, cooling blanket should be used cautiously.
