Fever, which is the regulation of body temperature at an elevated level, must be differentiated from hyperthermia. The pathogenesis of fever involves exogenous pyrogens acting on macrophages/monocytes to produce the endogenous pyrogen, interleukin-1, which acts on the thermoregulatory centre and also has important effects on the body's immune responses to infection. Fever by itself is rarely harmful, and there is no evidence that febrile seizures produce long-term sequelae. On the other hand, fever may be part of the body's innate protection against infection. The main reason for treating a fever in a child is to relieve discomfort. Acetaminophen should be the drug of first choice in treatment, and sponging, if used at all, should be employed only after acetaminophen has been given first. Education of parents about fever management can be helpful.
发热是指体温调节至升高水平,必须与体温过高相区分。发热的发病机制涉及外源性致热原作用于巨噬细胞/单核细胞以产生内源性致热原白细胞介素 -1,白细胞介素 -1作用于体温调节中枢,并且对机体针对感染的免疫反应也有重要影响。发热本身很少有害,而且没有证据表明热性惊厥会产生长期后遗症。另一方面,发热可能是机体抵御感染的固有保护机制的一部分。治疗儿童发热的主要原因是缓解不适。对乙酰氨基酚应作为治疗的首选药物,如需使用擦浴,也应在首先给予对乙酰氨基酚之后进行。对家长进行发热管理教育可能会有所帮助。
