体热的获得超过体热的放散,体温即升高。体温升高超过正常范围称体温过高。有以下几种类型。 1、生理性体温升高:见于小儿哭闹,妇女月经前期和剧烈运动时。 2、病理性体温升高:见于①外环境温度过高,湿度过大,机体靠排汗不足以排出过多的体热时,如在高温环境工作;②体表散热障碍,如大面积烧伤形成广泛的疤痕,汗腺缺乏症;③产热过多,如癲痫,甲状腺机能亢进;④中枢神经系统的损伤,导致体温调节障碍,如下视丘的损伤和脑肿瘤可致体温升高;⑤由于致热物质的作用,使体温调节中枢调定点上移,导致体温升高——发热。本文着重介绍后一种形式的体温升高。 Body heat gain more than body heat dissipation, body temperature that is elevated. Exceeding the normal range of body temperature called hyperthermia. There are several types. 1, physiological temperature increase: seen in children crying, women’s premenstrual and strenuous exercise. 2, the pathological temperature rise: found in ① outside the ambient temperature is too high, excessive humidity, the body by the perspiration is not enough to discharge too much body heat, such as work in high temperature environment; ② surface cooling obstacles, such as large area burn The formation of a wide range of scarring, sweat gland deficiency; ③ hyperthermia, such as epilepsy, hyperthyroidism; ④ central nervous system damage, leading to temperature regulation disorders, as the following hypothalamus injury and brain tumors can cause body temperature; ⑤ As a result of pyrogenic substances, so that the thermoregulation center set point up, leading to increased body temperature - fever. This article highlights the latter form of body temperature increase.
