1.What are the benefits of fever to the human body? What are the disadvantages? Fever requires more heat consumption, so it increases the work done by the lungs and heart, which has limited images for healthy children, but children with serious heart disease, severe anemia, lung disease and other diseases may be more detrimental to their health by bearing these extra burdens. In addition, some children may experience febrile convulsions due to high fever, often occurring between the ages of 6 months and 6 years. The common myth that “fever burns the brain” is not because the fever is directly damaging to the brain, but because the child is suffering from encephalitis, meningitis, etc. Fever is only one of the manifestations of these diseases, and it is the underlying diseases such as encephalitis and meningitis that cause damage to the brain. However, fever brings more than just bad effects to the human body. Many studies have shown that moderate fever can boost the body’s immunity, inhibit the reproduction of certain bacteria and help to clear them. A fever when humans are sick can be considered a protective instinctive response. 2, the baby has a fever, should I reduce the fever? If the fever is caused by too much clothing, heat stroke, etc., you can always reduce the fever by loosening the baby’s clothing, moving to a cooler place, or adding physical cooling. For fever caused by inflammatory diseases, if the temperature is not too high and does not cause any special discomfort, it is not necessary to actively reduce the fever, especially not immediately with medication, and it is not necessary to bring the temperature down to the normal range. It is not necessary to bring the temperature down to the normal range because even if the temperature is brought back to normal by physical cooling or medication, it is only superficially “normal” and the primary cause of the fever and inflammatory reaction is still present. Generally, the use of antipyretic drugs is only considered when the body temperature is 38.5 degrees or higher. Children with special diseases (chronic lung disease, heart failure, anemia, diabetes, febrile convulsions, etc.) can be considered to reduce fever when the body temperature exceeds 38 degrees. 3.How should I choose fever-reducing medicine for children? Fever in infants under 3 months of age is usually reduced by physical cooling methods, while children >3 months of age with fever can consider using acetaminophen or ibuprofen, which have similar duration of action and fever-reducing effects. These two drugs are recommended by the WHO as safe and effective fever reducers for children. Other drugs such as aspirin, anandamide, glucocorticoids, and nimesulide are not routinely used as fever reducers for children. If a child has a fever accompanied by symptoms such as runny nose and nasal congestion that cause more obvious discomfort, consider using a compound preparation i.e. a drug that contains ingredients to relieve several symptoms. If the child has a single symptom try to use compound preparations as little as possible, for example, if the child only has symptoms of fever, use only drugs that can reduce fever and do not use drugs that can also stop coughing and relieve nasal congestion. 4.What are the precautions when children take antipyretic drugs? (1) Choose the medicine for children, do not give your baby adult cold medicine on your own. (2) Even safe drugs need to pay attention to the dosage of drugs, the risk of side effects caused by overdose increases. Therefore, parents should learn to read the ingredients of the drugs, some drugs contain the same ingredients, pay attention to avoid duplication of medication. (3) Read carefully the instructions for use of the drug, especially the dose, adverse reactions, contraindications, and precautions when taking the drug. (4) When a child has a fever, the doctor will advise parents to give the child more water, because the body will sweat to dissipate excess heat in the body when the fever is reduced, so if the fever is reduced repeatedly, coupled with the child’s reduced appetite and reduced diet, some children will have a certain degree of dehydration, and need to pay attention to the appropriate replenishment of water and electrolytes, parents can give the child a small amount of liquid supplement (breast milk, porridge, soup, juice, etc.). (5) Antipyretic medicine is only a kind of medicine to relieve symptoms, even if the child does not have a fever after using the medicine, it is necessary to pay more attention to observe whether there are other symptoms manifested and seek medical attention in time. infants under 3 months of age with any degree of fever should seek medical attention as soon as possible.
