In recent days, many parents in the circle of friends have been struggling with their children's illness.
Causes of repeated fevers in children
1. Non-infectious fever: Not caused by various infectious diseases, aseptic substances or various inflammatory effects in the body temperature regulation center, body temperature central dysfunction or various causes of excessive heat production, heat loss, resulting in increased body temperature Higher than normal range.
2. Unexplained fever: The concept of generalized unexplained fever refers to all unexplained fevers. However, the narrow concept of fever is also used clinically, which means that fever is unexplained. Fever lasts for more than 3 weeks, and the body temperature is above 38. 5°C. After a detailed history, physical examination, and routine laboratory tests, the diagnosis cannot be confirmed.
3, central fever: refers to the central nervous system due to central nervous system disorders caused by abnormal body temperature caused by fever. Before diagnosis, fever due to systemic or local inflammation should be strictly excluded, and other causes of fever should be excluded. Intracranial diseases with fever are mostly critical cases, and most of them are caused by intracranial inflammation, lung infections, and urinary tract infections. For an unexplained moderate increase in body temperature, those who cannot find out the source of infection or the cause of infection at one time cannot easily be considered as a central fever. Should be repeatedly sought to exclude the cause of systemic or local infection, and pay attention to the reasons for drug fever and other fever.
4, continuous fever: When the mouth temperature is higher than 37. 3 °C or rectal temperature is higher than 37. 6 °C, the change between the day more than 1.2 °C, that is called fever. In accordance with the level of fever, can be divided into the following clinical divisions: Low fever 37. 4 °C ~ 38 °C Moderate heat 38. 1 °C ~ 39 °C High fever 39. 1 °C ~ 41 °C Ultra high fever 41 °C above, for 4 weeks Above, it is persistent fever.
Below 38.5°C, no need to use antipyretics
To clear pathogenic bodies such as these viruses, bacteria, and mycoplasma, in addition to the body's own immunity, it is often necessary for children to rely on drugs. However, Director Yu said that the use of imported drugs that are precisely targeted to the infection and expensive pathogens will not result in the immediate removal of pathogens, and treatment will take some time. Therefore, parents do not need to be so impatient. Parents need to do serious physical cooling and replenishment.
However, if the child has been in a high fever state, such as a body temperature of more than 39 °C, it should be given enough attention, because the long duration of high fever will have adverse effects on heart, lung, brain, gastrointestinal and other functions, especially 1 year to 3 years old. Half of the children are most prone to high fever convulsions and have some damage to the brain's nerve tissue. Therefore, in the use of anti-infective drugs, but also to the child for fever and other symptomatic treatment.
In general, infants and young children can be considered feverish if they measure rectal temperature above 37.8°C or phlegm temperature above 37.5°C. Yu Li pointed out that it is recommended that different measures be taken for different heat conditions -
(1) More than 37.5°C (can choose physical cooling)
(2) More than 38.5°C (can be taken orally to reduce fever)
(3) More than 39°C (injection can be used to reduce fever)
Drug cooling points
The principle is "can be taken orally without injection". Oral medications usually take about two hours to take effect. For high fever children, one can take oral antipyretics four times a day.
(1) It is generally not recommended to use multiple drugs at the same time to cool down. Cooling drugs are generally called "non-steroidal anti-inflammatory drugs," drugs, dosage forms are diverse, but due to similar principles, at the same time easy to use to make the temperature drop too hard, due to excessive sweating, or even cause collapse.
(2) An antipyretic drug can be reused. Since the root cause of the fever source was not removed, although the body temperature decreased after the drug was used, the heat source continued to affect the body and caused fever when the drug effect passed. Therefore, “I saw the disease in the morning, I finished the needle and burned in the afternoon. "It's not strange." Therefore, when your child's body temperature exceeds 38.5°C again, you can take antipyretics again. However, if you really want to get rid of the fever, you still need to eliminate the infection.
(3) Non-steroidal anti-inflammatory drugs have some side effects and these drugs should be used under the guidance of a doctor.
(4) Infants less than three months old do not advocate using any antipyretic drugs when fever, but should take physical cooling.
Physical cooling points
Different from adults, children can't rely on wearing more clothes and sweat to cool down. This is because the children's body temperature regulation and development is not perfect, and it is prone to dehydration and shock.
(1) Drug cooling and physical cooling can achieve better antipyretic effects. The general practice is to use an antipyretic or ice pack deposited on the forehead, with warm water, 33% alcohol constantly wipe the neck, armpit, thigh skin, or warm bath.
(2) When the child feels cold or cold hands and feet, it is not appropriate to do physical cooling, but at this time should pay attention to keep warm, use clothes to be covered with hands and feet or drink hot water, and other hands and feet become hot, we must remove the clothing Start physical cooling.
(3) The site of physical cooling should avoid the pre-area, palms, and soles of the feet in order to avoid adverse effects caused by local stimulus-induced conditions. It is also not appropriate to swab alcohol or apply ice to the whole body. The neck, axillary, and thigh roots are selected because the large arteries pass through these areas. The effect of heat dissipation is better.
