First, do not rush to reduce fever There are several reasons not to rush to the pediatric fever: 1, body temperature 37.5-38 ℃ for low fever, 38-39 ℃ for medium heat, 39 ℃ or more for high fever. Low or moderate fever is conducive to pediatric growth and development. Fever is a reaction of the body to the invasion of viruses or bacteria. This reaction is conducive to the annihilation of invasive viruses and bacteria, which is conducive to the normal growth and development of children. 2, not to high fever do not use drugs. Body temperature reaches 39 degrees or more must be used, and urgent. High fever persists for too long, which can make many important functions of the body dysfunctional; increase the burden of heart and blood vessels due to the consumption of oxygen and nutrients; excessive brain excitation leading to hyperthermia convulsions or excessive inhibition caused by lethargy; digestive disorders; weakening of resistance, combined with pneumonia and so on. 3, antipyretic drugs have big side effects, do not use as a last resort. Whether it is paracetamol, compound aspirin (APC), or a variety of other antipyretic drugs, are inseparable from aspirin, caffeine, finasteride to synthesize. Therefore, antipyretic drugs have large side effects: stimulation of the gastric mucosa, destruction of appetite, worsening of gastric ulcers and even hemorrhage, causing small amounts 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 toxicity and death. Newly developed cold and flu medicines are mostly acetaminophen (paracetamol) based compound preparations, is the first choice of antipyretic drugs for children over 2 months, antipyretic and analgesic effect is similar to aspirin, but the side effects are small, gastrointestinal reaction is light, there is no obvious bleeding tendency. In recent years, some scholars advocate the application of new non-steroidal anti-inflammatory drugs, such as ibuprofen, naproxen, etc., because most of the fever is related to endogenous pyrogens. Secondly, the development of new cold medicine compound preparation contains nasal vasoconstrictor and anti-allergic drugs for the relief of nasal congestion, runny nose, headache, general discomfort and other symptoms. Similar medications include Contac and cold capsules, which can relieve cold and flu symptoms. The drugs can be chosen according to the condition, and Kerratan can also be used in appropriate cases. 4, reduce room temperature (summer), remove excessive clothing, ensure that the child is in a cool (but not cold) ventilation environment. In the past, we advocate the use of physical and 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 high fever, parents do not have to be more and more nervous, as long as the above suggestions, observe the child’s mobility, supplemental hydration, moderate antipyretic when necessary. The higher the body temperature, the smaller the dose of antipyretics, so as not to quickly and excessively reduce fever caused by defecation. To take the child to the doctor in time. Second, the rational use of drugs pediatric colds do not just use antibacterial agents, should choose to use some antiviral drugs, because colds are caused by viruses. Antiviral drugs are: 1, some only inhibit DNA-type viruses, such as acyclovir (acyclic guanosine), adenosine, cytarabine, cyclic cytarabine, trifluridine, etc., Keratin is a new generation of acyclovir replacement broad-spectrum antiviral. 2, some of them are against RNA, RNA, RNA and RNA. 2, some of the RNA-type viruses also have a role, such as ribavirin (triazole nucleoside). 3, in addition to the above, there are amantadine, interferon and its inducers also have a better antiviral effect. 4, Dipyridamole (Dipyridamole) on pediatric viral upper respiratory tract infections and pediatric herpes pharyngitis also has a therapeutic effect. 5, many herbs, such as Andrographis paniculata, Panax quinquefolium, Da Qing Ye, Honeysuckle, Di Ding, Scutellaria baicalensis, Comfrey, Guanzhong, Rheum palmatum, Yin Chen, Tiger Balm and so on can be used in the prevention and treatment of certain viral infectious diseases. 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.Blood test leukocyte count is obviously increased. 4.Frequent tonsillitis. 5.Those who have tracheitis (cough, purulent sputum) or signs of pneumonia. Fourth, when applying antiviral drugs, antipyretic drugs and antimicrobials, the following points should be noted: 1. The dose should not be too large, and the time of administration should not be too long. 2, in addition to medication, need to take appropriate rest, drink more water, eat light and easy to digest food, children less activity, pay attention to wear a mask. 3.Paracetamol should not be used in children under 3 years old because their liver and kidneys are not yet mature. 4, the child himself or his family has a history of allergy to antipyretic drugs, do not use antipyretic drugs. 5, do diagnose cold, then do not use corticosteroids. Fever can not abuse prednisone, dexamethasone and other glucocorticoid drugs, glucocorticosteroids have a temporary fever-reducing effect, but glucocorticosteroids can not be treated as a “universal” antipyretic, see the fever on the use of, it is harmful. Feverish diseases with glucocorticoid drugs have strict indications, should be closely monitored by a doctor under the application of the results of abuse can make the body’s immune function disorders, weakening the body’s resistance, leading to the spread of infection spread and aggravate the condition.
