Three areas are generally measured for body temperature measurement, namely the oral cavity, armpit and anus. The normal temperature of a child’s armpit is generally between 35.9℃-37.2℃; the normal temperature of a child’s mouth is generally between 36.2℃-37.3℃; and the normal temperature of a child’s anus is generally between 36.5℃-37.5℃. If the measurement result is within the above range, all are considered normal body temperature. However, parents need to note that any measurement above 0.5℃ above the normal range is considered feverish; those not exceeding 38℃ are considered hypothermic; if it exceeds 39℃, it is considered hyperthermic. To avoid errors, measurement should pay attention to the following points: 1, oral temperature measurement: the first 75% alcohol to disinfect the thermometer, and then placed under the tongue, tightly closed lips, placed 5 minutes after taking out the reading can be; 2, axillary temperature measurement: dry the armpit sweat, the mercury end of the thermometer placed in the bottom of the fossa top, and then the upper arm clamping thermometer to avoid the child moving, 10 minutes after the reading can be. This method is not easy to cross-infection, is the most commonly used method of measuring body temperature; 3, anal temperature measurement: mostly used for comatose patients or children, the patient supine position, the head of the anal table with oil lubrication, and then slowly inserted into the anus, deep into the anal table until 1/2, placed after 3 minutes can be read.
