1. Commonly used western medicine antipyretics Commonly used antipyretics include acetaminophen (Baifuzai, Tylenol, etc.), ibuprofen (Chen Gong Zaixin, Merrill Lynch), aspirin (Aben tablets, bamir) and indomethacin (indomethacin). These drugs have some irritation to the gastrointestinal tract and should be paid attention to. Acetaminophen Acetaminophen is the most commonly used antipyretic in pediatric clinic, and it is also the first choice antipyretic recommended by the World Health Organization (WHO) for infants and children over 2 months with high fever. Acetaminophen is a relatively safe antipyretic with rapid and reliable antipyretic effect and few adverse reactions, which can be kept at home. Its trade names are Tylenol, Baifuning, Yidiqing, Bilitong, Anjiare, Aier, Xiaoer Antipyretic Suppository, etc. There are many dosage forms, which are suitable for children. Ibuprofen is a relatively new drug for relieving fever and pain. It is safe and efficient in pediatric fever, and is suitable for children over 6 months and adults. Its antipyretic effect is stronger than acetaminophen and aspirin, and it has little gastrointestinal irritation and no influence on hematopoietic system. It can replace intramuscular injection of antipyretics and is suitable for children with high fever caused by infectious diseases. Commonly used trade names are Thorne, Merrill Lynch and so on. Aspirin Aspirin is an antipyretic with a long history. However, due to its strong acidity and large gastrointestinal irritation, large doses can cause nausea and vomiting, aggravate or induce ulcer disease, and induce Raynaud's syndrome and kidney damage. The United Kingdom clearly stipulates that aspirin is prohibited for children under 16 years old. At present, the drug is rarely used in pediatrics in China. Compound aminopyrine Compound aminopyrine, also known as Antongding, is one of the most commonly used powerful antipyretics. The medicine can induce acute hemolytic anemia and rash. In addition, if the injection dose of this product is too large, the child will sweat too much and his body temperature will plummet, which will easily lead to collapse. Therefore, compound aminopyrine is prohibited for infants and young children, and should be used with caution for older children. Anemone has obvious antipyretic effect, but its toxic and side effects are obvious. Long-term application can cause granulocytopenia, purpura, and even aplastic anemia. Some patients are allergic to the drug, and even have shock and even death. At present, many countries, including China, prohibit or restrict the use of metamizole sodium. Among antipyretics, pediatricians usually recommend Tylenol, the main component of which is acetaminophen (also known as paracetamol); And Merrill Lynch, the ingredient is ibuprofen. If acetaminophen can't bring down the fever, you can use Merrill Lynch. It should be noted that Tylenol's interval is 8 hours, and Merrill Lynch's interval is 4 hours. You can't make a mistake. 2. Commonly used Chinese medicines-There are tricks to choose three treasures for emergency and antipyretic drugs. Although Angong Niuhuang Pill, Zixuedan and Zhibaodan are all representatives of clearing away heat and inducing resuscitation, their medicinal properties are different. Angong Niuhuang Pill is the coolest, followed by Zixuedan and Zhibaodan. Angong Niuhuang Pill is suitable for those patients who have a high fever and are unconscious, as if they were "in a fog". Zixuedan is suitable for patients with high fever, irritability and even coma accompanied by convulsions, hand and foot convulsions and frequent banging sounds. However, Zhibaodan is more suitable for patients who are in a coma with fever and phlegm, and behave quietly, because many fragrant medicinal materials are used in the prescription. Based on these characteristics, the Chinese medicine community has passed down their know-how from ancient times to the present, so there is a saying that "Ping Ping Zi Xue Dan, silent to Baodan, confused Niuhuang Pill". Whether it is a western medicine antipyretic or a Chinese medicine antipyretic, it is recommended to take it under the doctor's advice! Don't use drugs indiscriminately, otherwise it may be counterproductive! 3. What to do when the child has a fever? Whether the child has a fever or not is always a controversial topic among experts! Personally, I think this should be treated differently: on the one hand, it is necessary to know a self-protection reaction of the human body when you have a fever, which is conducive to eliminating viruses and bacteria! On the other hand, persistent high fever will cause other adverse reactions and syndromes, so dealing with high temperature must be treated dialectically like Chinese medicine! It is very unwise to completely let go or take antipyretics as soon as you see a fever! It is very common for children to catch a cold and have a fever. At this time, parents are often extremely anxious. Therefore, they always hope to use antipyretics to cool down immediately to achieve the purpose of fever and disease removal. However, according to medical research, it is not necessarily a bad thing for children to have a fever. If the temperature drops blindly, it will be even worse for the recovery of the disease. The cause of fever is that the body temperature rises after viruses and germs invade the human body. At this time, the increase of body temperature can stimulate the bone marrow to produce a large number of white blood cells, and white blood cells have the ability to devour viruses and germs, which can control the reproduction of viruses and germs in the human body. Therefore, the increase of body temperature can enhance the patient's own immune function and disease resistance, which is completely a self-protection immune behavior of the human body. If you blindly use drugs to cool down, it will help the bacteria, but it is not conducive to treatment. In addition, the characteristics of fever are valuable for the diagnosis of some diseases. If antipyretics are abused and used urgently, it will disrupt the characteristics of fever and bring certain difficulties to disease diagnosis.
