Knowledge of fever treatment
Fever is to remove harmful substances.
There is a thermoregulatory center in the hypothalamus of our head. Under normal circumstances, the cells and tissues of various organs of the human body need a constant body temperature of about 37℃ to function. When some bacteria, viruses, parasites and other microorganisms or other substances enter the body to attack and harm the body, the body will immediately fight back and produce a substance called endogenous pyrogen in the body. This substance acts on the hypothalamus, which can raise the set point of human body temperature, raise body temperature, accelerate metabolism, increase more white blood cells, macrophages and inflammatory factors in the immune system, and is more conducive to eliminating harmful substances such as microorganisms. However, sustained high fever above 40℃ will weaken the body's metabolic nutrition and reduce immunity.
What happens to the body when you have a fever?
I have a fever, and everything is getting faster. The nervous system is very active, you will feel very excited, your heart rate will increase, your breathing will deepen and your immune function will improve. At the same time, your body's metabolic rate will also increase. Every time the temperature rises 1℃, your basal metabolic rate will increase 13%. The consequences are: the central nervous system is excited, and you will be bored and unable to sleep; Sympathetic nerve is active, which inhibits the secretion of digestive juice, and you will lose appetite, abdominal distension and constipation; With the increase of metabolic rate, the body's demand for energy also increases, so it is necessary to supplement more energy and water. Under the low heat of 38.5℃, there is generally no danger, so don't be nervous. If high fever persists, it will obviously increase tissue consumption, on the one hand, it will increase the load of organs, and may even induce dysfunction of corresponding organs, on the other hand, it will cause tissue damage, swelling and degeneration of organs and tissues such as kidney, liver and myocardium.
Common western medicine antipyretics
Western medicine has a strong antipyretic effect, and it is easy to sweat a lot after use, which can make the body temperature drop rapidly in a short time, but it is easy to cause dehydration and electrolyte disorder, so western medicine antipyretics are more suitable for adults.
Commonly used antipyretics are: paracetamol, which is widely used in all kinds of people with colds and fever (including the elderly and children). You should not drink alcohol or alcoholic beverages while taking the medicine. Can not be combined with some compound cold medicines (white plus black, Ganmaoling, etc.). ) At the same time, it may produce adverse reactions.
Ibuprofen, suitable for children over 6 months, is used for children with high fever caused by infectious diseases, and cannot be used together with compound cold medicines containing ibuprofen (Novolay, Effie, etc.). ).
Aspirin, used when cold and fever are accompanied by cough and expectoration, has great stimulation to gastrointestinal tract and obvious inhibitory effect on platelets. Patients with digestive tract ulcer and recent active bleeding should use it with caution or not.
Indomethacin is suitable for chronic high fever or cancerous high fever. It should be used with caution, preferably under the supervision of a doctor. Taking it immediately after meals can reduce gastrointestinal reactions.
Analgin (Antong injection), Antong injection is a classic antipyretic injection, which is suitable for high fever. When the above antipyretic drugs are ineffective, they should be injected again.
Cooling method below 38.5℃
Wet compress to cool down. Just like in TV series, put a wet towel on your forehead and change it frequently.
Alcohol bath. This method is rarely used at present. It should be noted that the alcohol concentration is 25%~50%, otherwise it will easily irritate the skin and absorb a lot of water from the epidermis, causing harm to the skin.
In general, if the body temperature is lower than 38.5℃ and the patient is in a good mental state, there is no need to take antipyretics. Appropriately raising the body temperature can improve the immunity of patients and help the human body resist invading pathogens.
