发热是小儿最常见的症状之一,家长发现孩子发热,往往急得不知所措。那么,发热到底是怎么回事,在家护理发热的小儿应该注意些什么呢? 我们知道,正常人口腔温度为37℃,肛门温度比口腔温度高约0.5℃,而腋下温度则比口腔温度低约0.5℃。人体因为不断进行新陈代谢,就会产生热量,如果婴儿过度活动或长时间啼哭都可使温度增加。散热主要通过呼吸道、皮肤小血管、出汗多来完成。在正常情况下,产热和散热保持平衡,才能维持人体的正常温度。如果这个平衡发生倾斜,即产热增加,散热减少,则会引起发热。一般认为,口腔温度37.5℃以上为发热,37.5℃～38℃称低热,39℃以上为高热,体温≥40.5℃为超高热。小儿发热最常见的原因是由感染性疾病造成的,如感冒、扁桃体炎、肺炎、败血症等。发热是肌体抵抗疾病的一种积极反应,只要诊断正确,积极进行抗感染治疗,再加上适当的退热治疗和护理,问题就会迎刃而解。那么,发热到什么程度需退热治疗呢?一般认为,当小
Fever is one of the most common symptoms in children. Parents find their children feverish and often anxious overwhelmed. So, fever in the end is how the matter, at home, nursing children with fever should pay attention to what? We know that the normal oral temperature is 37 ℃, anal temperature is about 0.5 ℃ higher than the oral cavity temperature, while the armpit temperature is lower than the oral cavity temperature About 0.5 ° C. The body generates heat due to constant metabolism, which can be increased if the baby is over-active or prolonged crying. The main heat through the respiratory tract, skin, small blood vessels, sweating and more to complete. Under normal circumstances, heat and heat to maintain a balance in order to maintain the body’s normal temperature. If this balance is tilted, that is, increased heat production, reduce heat dissipation, it will cause fever. Generally believed that the oral temperature 37.5 ℃ for fever, 37.5 ℃ ~ 38 ℃ said low fever, 39 ℃ above the fever, body temperature ≥ 40.5 ℃ for the ultra-high fever. The most common cause of fever in children is caused by infectious diseases, such as colds, tonsillitis, pneumonia, sepsis and so on. Fever is a positive response to the body’s resistance to disease. As long as the diagnosis is correct, active anti-infective therapy, coupled with proper antipyretic treatment and care, the problem will be solved. So, what degree of fever to be anti-fever treatment? It is generally believed that when small
