产褥中暑是指产妇在室内高温闷热环境下,体内余热不能及时散发,从而引起机体体温调节发生障碍的一种急性疾病。正常人体内物质氧化代谢和肌肉活动不断产热。但在体温中枢调节下,一般借助于皮肤血管扩张、血液循环加速和汗液增多,通过辐射、对流、传导、呼吸和蒸发等方式散热,使产热和散热基本上处于平衡,以维持体温在36°～37℃之间。但当周围气温超过35℃以上时,很难通过辐射、对流方式来散热,机体只有依靠大量汗液蒸发进行散热。
Puerperal heatstroke refers to the maternal high temperature in the indoor hot environment, the body heat can not be distributed in a timely manner, causing the body temperature regulation of an obstacle to an acute disease. Normal human body oxidative metabolism and muscle activity continue to produce heat. However, in the thermoregulatory center, generally by virtue of the skin vasodilation, accelerated blood circulation and increased sweat, by radiation, convection, conduction, breathing and evaporation and other means of cooling, so that heat and cooling are basically in balance to maintain body temperature at 36 ° ~ 37 ℃ between. But when the ambient temperature exceeds 35 ℃ above, it is difficult to radiate, convection way to heat, the body only rely on a large amount of sweat evaporation to heat.
