Do not rush to reduce fever. There are several reasons for not rushing to reduce fever in children: 1. A body temperature of 37.5-38°C is low fever, 38-39°C is medium fever, and more than 39°C is high fever. Low or medium fever is good for the growth and development of children. Fever is a reaction of the body to the invasion of viruses or bacteria. This reaction is conducive to the annihilation of invading viruses and bacteria, thus contributing to the normal growth and development of the child. Ningxia Institute of Traditional Chinese Medicine, Department of Pediatrics, Zhao Ying 2, do not use medicine until the fever is high. A body temperature of 39 degrees or more must be medicated. High fever lasting too long can cause dysregulation of important body functions; increase the burden on the heart and blood vessels due to high oxygen and nutrient consumption; excessive brain excitement leading to febrile convulsions or excessive inhibition causing lethargy; digestive disorders; weakened resistance, combined with pneumonia, etc. Except for children with a history of febrile convulsions. 3, antipyretic drugs have large side effects, not as a last resort. Aspirin has greater side effects: stimulate the gastric mucosa, destroy appetite, cause a small amount of long-term gastrointestinal bleeding and thus lead to iron deficiency anemia; cause blood disorders; damage to the liver and kidneys; severe allergic reactions, manifested as exfoliative dermatitis combined with liver and kidney poisoning and death. In recent years, some scholars advocate the application of new non-steroidal anti-inflammatory drugs, such as ibuprofen (Merlin, Torn, TenCen, Fenbendazole), naproxen, etc., because most fevers are related to endogenous pyrogens. Newly developed cold medicine mostly acetaminophen (paracetamol) based compound, is the preferred antipyretic for children over 2 months of age, antipyretic and analgesic effect is similar to aspirin, but the side effects are small, gastrointestinal reactions are light, and there is no obvious bleeding tendency. Secondly, the development of new cold medicine compound contains nasal vasoconstrictors and anti-allergic drugs, used to relieve nasal congestion, runny nose, headache, general discomfort and other symptoms. Similar drugs are Contec, cold capsules, etc., which can relieve cold symptoms. According to the condition of the choice of drugs, kairetan can also be appropriate to choose. 4, lower the room temperature (summer), remove excessive clothing, ensure that the child is in a cool (but not cold) ventilation. In the past, the use of physical, drug cooling, as appropriate, but WHO does not advocate the traditional application of cold, warm water or alcohol baths in high fever cooling methods, research has proved that this method violates the physiological mechanism. 5, baby fever, parents do not have to become more and more nervous, as long as the various recommendations mentioned above, observe the child’s mobility, hydration, moderate antipyretic if necessary. The higher the body temperature, the smaller the dose of antipyretic drugs used, so as not to quickly and excessively reduce fever caused by deficiency. It is important to take the child to the doctor promptly. Indications for combining antibiotics: 1. When the fever does not subside even after taking antiviral drugs. 2.Prevent secondary bacterial infection in infants under 6 months of age. 3.Significant increase in total white blood cell count in blood test. 4.Persons who frequently suffer from tonsillitis. 5.People with tracheitis (cough, pus sputum) or signs of pneumonia. When applying antivirals, antipyretics and antimicrobials, the following points should be noted: 1. The dose should not be too large and should not be taken for too long. 2. In addition to medication, good rest is needed. To prevent complications of myocarditis, bed rest is required at the beginning of the disease. Also drink more water, eat light and easy to digest food, children less active, pay attention to wear a mask. It is not necessary to give intravenous fluids (saline, vials, drips, etc.) if you can get water. When not dehydrated, IV fluids should be given slowly to avoid increasing the burden on the child’s heart. Intravenous fluids are by no means a panacea. 3, the child himself or his family has a history of allergy to antipyretic drugs, do not use antipyretic drugs. 4. Do not use corticosteroids if you do diagnose a cold. Glucocorticoids such as prednisone and dexamethasone should not be abused to reduce fever. Although glucocorticoids have a temporary antipyretic effect, they should not be taken as antipyretic drugs, and it is harmful to use them when you see fever. There are strict indications for the use of glucocorticoids in febrile diseases, and they should be applied under the close monitoring of doctors. The result of abuse can disrupt the immune function of the body, weaken the body’s resistance, lead to the spread of infection and aggravate the disease.
