Fever is both beneficial and harmful to the body. The body’s immune function is significantly enhanced during fever, which facilitates the clearance of pathogens and promotes healing. Viral respiratory infections account for 70-80% of acute respiratory illnesses. Usually fever caused by respiratory diseases, most of the upper respiratory tract infections caused by viruses have a fever duration of 3-5 days; among them, purulent tonsillitis, when fever is high, especially on the first 1-2 days of the disease, the fever peak is 39-40°C, the effect of antipyretic is poor, the fever lasts long, usually within 5 whole days; while pneumonia, the fever duration varies depending on the causative agent and the type of inflammation caused, bronchopneumonia, usually The fever is often longer, often 7-10 days, or even 12-15 days, and parents are easily impatient when fever is present, even impatient, and even bad-mouthing the doctor. Wrong way: 1. Avoid dressing too much. Too much clothing, hindering the distribution of heat and evaporation, are not beneficial to the fever. 2, avoid fever reduction too fast. Fever too fast, too violent, can lead to a large loss of body fluids, causing a drop in blood pressure, and even shock, so the fever should be gentle, should not be too fast. 3, think fever will “burn the child silly”, this is no basis, unless the child itself is very serious encephalitis caused by fever, or the child is “muffled fever syndrome” caused by fever, otherwise the general fever below 40 ℃, as long as good active cooling If the fever is below 40 degrees Celsius, as long as you do a good job of actively cooling the temperature and avoiding convulsions, the effect on the brain is not significant. The right way: physical cooling is safer. 1. Drink more water. Drinking water can replenish the water evaporated due to fever. Sweating after drinking water and evaporation of water can help reduce fever. In addition, increased urination can also make part of the heat carried out by urine, accelerating the reduction of fever. 2, physical cooling: appropriate antipyretic measures should be used. Physical cooling, safe, simple and reliable, is the preferred antipyretic measures. Ice or cold water (or cooling paste) can be used on the head and neck, axillae and bilateral groin fever reduction method. Bathing with warm water around 30℃ can make the skin capillaries dilate and accelerate the evaporation of water, which is also a fairly simple method of reducing fever. When the effectiveness of physical cooling methods is not good, you can choose the appropriate antipyretic drugs under the guidance of a doctor. 3, children with a previous history of febrile convulsions or family history need to beware: actively do a good job of cooling treatment when fever is high, and pay attention to the higher fever when 38.5 ℃ (axillary temperature), need antipyretic drugs, if necessary, oral anti-convulsant drugs (such as: luminal).
