一、微热的概念根据克莱姆珀勒(Klempere)的分类,36～37℃为正常体温,37.1～38℃为微热,38～38.5℃为轻度热,38.5～39.5℃为中度热,39.5～40.5℃为高热,40.5℃以上为超高热。慢性微热在临床上是一个极为复杂的难题。病人客观检查阳性体征甚少,常以抗感染、抗结核、抗风湿药物等试验治疗,多数难以收效。不少病人以“微热待查”辗转就医不得确诊。二、微热的诊断 (一)首先确定是否为微热:必须了解正常体温的变异。所谓正常人体温低于37℃,是指大多数人的平均值,少数正常人体温可低于36.5℃或高于37.1℃。儿童因代谢率较高,其体温较成人为高;月经前和妊娠期的生理性短期体温升高,不能误诊为病理性发热。
First, the concept of micro-heat According to Klempere classification, 36 ~ 37 ℃ for the normal body temperature, 37.1 ~ 38 ℃ mild fever, 38 ~ 38.5 ℃ mild fever, 38.5 ~ 39.5 ℃ moderate Heat, 39.5 ~ 40.5 ℃ for high fever, 40.5 ℃ for the ultra-high fever. Chronic fever is clinically a complex problem. Objective examination of patients with few positive signs, often with anti-infection, anti-TB, antirheumatic drugs and other experimental treatment, the majority of difficult to benefit. Many patients with “micro hot to be investigated ” was removed for medical diagnosis. Second, the diagnosis of micro-fever (A) First determine whether it is mild fever: you must understand the normal variation of body temperature. The so-called normal body temperature below 37 ℃, refers to the average of most people, a few normal body temperature can be lower than 36.5 ℃ or higher than 37.1 ℃. Children due to higher metabolic rate, the body temperature is higher than adults; premenstrual and gestational physiological short-term body temperature, can not be misdiagnosed as pathogenic fever.
