一、发热与体温过低新生儿的体温调节是不够稳定的,尤其早产儿更是如此,这主要与新生儿的生理特点有关:1.中枢神经系统发育不完全,因而调节体温恒定的产热与散热过程尚未完善。2.代谢低,热量形成不足。3.体表面积大,散热面积比成人相对增加,且出汗及战栗 First, the fever and hypothermia Neonatal body temperature regulation is not stable enough, especially premature children, especially with the physiological characteristics of the newborn: 1. Central nervous system development is not complete, thus regulating the body temperature constant heat And the cooling process is not perfect. Low metabolism, lack of heat formation. 3. Body surface area, heat dissipation area is relatively increased than adults, and sweating and shivering
