1. What are the benefits of fever to the human body? What are the disadvantages? Fever requires more calories to be consumed, so it increases the amount of work done by the lungs and the heart. This has a limited effect on healthy children, but children with severe heart disease, severe anemia, lung disease, and other illnesses may have a more detrimental effect on their health as a result of these excess burdens. In addition, some children may develop febrile convulsions as a result of high fever, often occurring between the ages of 6 months and 6 years. The common myth of “brain damage due to fever” is not that the fever causes direct damage to the brain, but rather that the child is suffering from encephalitis, meningitis, etc. Fever is only a manifestation of these diseases, and it is the underlying disease, such as encephalitis or meningitis, that causes damage to the brain. But fever brings more than just bad things 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 get rid of germs. Fever when human beings are sick can be said to be a protective instinctive response. 2, the baby has a fever, should the fever be reduced? If the fever is caused by too much clothing, heat stroke, etc., the fever can be reduced at any time by loosening the baby’s clothing, transferring to a cooler place, or adding physical cooling. For fever caused by inflammatory diseases (cold, pneumonia, pharyngitis and other fever are in this category), if the body temperature is not too high and does not cause special discomfort, then there is no need to actively reduce the fever, especially do not need to use medication right away, there is no need to bring the body temperature down to within the normal range. It is not necessary to lower the body temperature to the normal range, because even if the use of physical cooling or medication to bring the body temperature back to normal, it is only the surface of the “normal”, causing fever and inflammatory reaction of the primary disease is still there. In general, the use of antipyretic drugs should be considered only when the body temperature is 38.5 degrees or higher. Children with special diseases (chronic lung disease, heart failure, anemia, diabetes, had febrile convulsions, etc.) can be considered when the body temperature exceeds 38 degrees to give fever. 3, how to choose children’s antipyretic? Fever in infants under 3 months of age is usually lowered by physical cooling methods, and children >3 months of age with fever can consider using acetaminophen or ibuprofen, which have similar duration of action and fever-reducing effects, and are generally available in either form. These two drugs are recommended by the World Health Organization (WHO) as safe and effective antipyretics for children, while other drugs such as aspirin, analgin, glucocorticosteroids, and nimesulide are not routinely used as antipyretics for children. If your child’s fever is accompanied by symptoms such as runny nose and nasal congestion that cause significant discomfort, consider using a combination of medications, i.e., one medication that contains ingredients to relieve several symptoms. If the child has a single symptom as little as possible to use compound preparations, for example, if the child only has fever symptoms, only fever reducer, do not need to use also can relieve cough nasal congestion of the drug. 4.What are the precautions for children taking antipyretics? Choose drugs for children, do not give your baby adult cold medicine by yourself. Again safe drugs should also pay attention to the dose of drugs, overdose caused by the increased risk of side effects. Therefore, parents should learn to read the ingredients of the medication. Some medications contain the same ingredients, so be careful to avoid double dosing. Children with fever doctors will advise parents to give children more water, because the body will sweat to emit excess body heat, so if repeated fever fever, coupled with the child’s appetite to reduce diet, some children will have a certain degree of dehydration, the need to pay attention to water and electrolyte supplementation of the right amount, parents can give the child a small number of supplemental fluids (breast milk, porridge, soup, fruit juice, etc.). Lastly, we emphasize: antipyretics are only a kind of medication to relieve the symptoms, even if the child does not have a fever after using the medication, we should pay more attention to observe whether there are other symptoms, and consult a doctor in a timely manner. infants under 3 months of age who have a fever of any degree should consult a doctor as soon as possible.
