Fever is the most common symptom in children, and everyone has a fever in childhood. Excessive fear and anxiety of children's fever are common among most parents, including those with higher education, which leads to overtreatment of fever. It is common for some parents to go to the hospital three or four times a day when their child has a fever, and urgently ask the doctor to give the child multiple intramuscular fever-rejecting needles, or even unreasonably apply hormonal drugs to relieve fever, leading to some serious consequences that could have been avoided. This phenomenon is called "fever phobia" abroad.
The relative stability of human body temperature is achieved under the control of the body temperature regulation center. It is generally considered that rectal temperature (anal temperature) above 38 degrees Celsius is called fever, and oral and axillary temperatures are lower than the anal temperature by 0.5 and 0.8 degrees Celsius, respectively. . Modern research suggests that fever is both a symptom of a disease and one of the body's anti-infective mechanisms. When the body is attacked by foreign pathogenic microorganisms (exogenous pyrogens) or the release of certain substances in the body (endogenous pyrogens) is increased, a fever effect is generated. The body temperature adjustment center moves the body temperature adjustment point upward, causing a rapid heartbeat and skeletal muscle contraction Such as, increase heat production, terminal blood vessels constriction, sweat pores closed, etc., reduce heat dissipation and increase body temperature. Clinically, fever in children with extremity cold, chills, and chills can be seen. The fever mechanism is actively regulated and rarely exceeds 41 degrees Celsius.
Studies have shown that various immune function (ie, human resistance) indicators in the human body during fever are better than when the body temperature is normal. This is the body's emergency mobilization of various resistance forces throughout the body to fight against foreign pathogenic microorganisms and adjust the body's physiological balance. Animal experiments have shown that many lower animals also have fever when infected, and fever can improve their survival rate. If antipyretic measures are given, the survival rate decreases. This is the side of fever that is good for life. Of course, fever also has a harmful effect on the human body. High fever is not good for babies with acute upper respiratory infections. Children with extreme failure or severe lung and cardiovascular diseases are damaged due to fever increasing oxygen consumption and heart rate. Excessive fever can also cause nervous system damage. Children under 5 years of age, especially at the age of 6 months to 3 years, are at risk of developing febrile seizures.

Whether or not to give antipyretic treatment needs to be determined on the basis of weighing possible benefits (improving the comfort and behavior of children) and disadvantages (side effects of drugs). The World Health Organization recommends that in general antipyretic treatment should only be used for young children with high fever, that is, anal temperature of 39 degrees Celsius or above. Acetaminophen is recommended as the drug of choice for fever in children with acute upper respiratory tract infections at a dose of 10-15 / mg per kilogram of body weight, orally.
Because fever is often accompanied by an increase in metabolic levels and an insignificant loss of water, children with fever must be encouraged to increase fluid intake. Reasonable supplementation of water can help dilute respiratory secretions and have expectorant effects. Give the child nutritionally rich, light, and easily digestible food, wear appropriate clothing, maintain indoor ventilation, and a neutral temperature environment. External cooling methods, such as undressing, bathing, scrubbing with cold or warm water, or scrubbing with alcohol, are not recommended. Because the physical cooling method is also in contradiction with the physiological mechanism, unless the hypothalamic temperature setting point has been lowered by drugs in advance, children's exposure to the body or scrubbing with water or alcohol will only cause body tremors and skin goose bumps. In addition, alcohol can be absorbed by children's delicate skin, reaching dangerous levels of poisoning in blood. Alcohol scrubs are not recommended.

What to do if the baby has a fever?
Fever refers to the abnormal increase in the baby's body temperature. The mother's hand is not a thermometer and cannot accurately measure the baby's body temperature; while the normal underarm temperature of the baby should be 36 ° C to 37 ° C, and it can only be considered fever if it exceeds 37.4 ° C. Seasonal climate changes are many and it is a cold for children (also called upper respiratory infections)

Baby's fever management principles The cause of fever is mainly caused by diseases, such as: respiratory infections, meningitis, urinary tract infections, etc., so the cause of the fever should be found out in a timely manner, and the fever can be treated with the right medicine. If the body temperature is unstable, it means that the disease has not healed, the disease is cured, and the fever subsides.
