The child's body has not yet fully developed. Children at this time are very prone to problems, especially fever. This makes mothers very anxious and nervous, feeling that their children seem to have a big problem. So what's the reason why children always have recurrent fever?
Why do children have recurrent fever?
It is difficult to adapt to the external environment, the immune function has not fully developed, or the temperature rises sharply after fever subsides. A slight mistake may lead to recurrent fever. Generally speaking, fever is mainly caused by viruses and bacteria invading the body, triggering respiratory or gastrointestinal infections. In addition, there are several reasons as follows:
1. Unexplained fever
Generalized: All patients with unexplained fever.
Narrowly defined: Generally speaking, in clinical medicine, the narrow meaning of fever is also used. The fever has lasted for more than 3 weeks, and the child's body temperature has exceeded 38.5 degrees Celsius. Despite careful examination of the medical history, physical examination, and routine laboratory tests, the cause of the illness cannot be determined.
2. Non infectious fever
It is not caused by various infectious diseases, but by various inflammations and other factors that disrupt the central system of body temperature regulation, or by various reasons that cause the body to produce more heat but release less, resulting in an increase in body temperature that is different from normal temperature.
3. Central fever
This is also one of the reasons for recurrent fever in children. The reason is that pathological changes in central nervous system function lead to confusion in the temperature regulation center, resulting in fever. The baby's nervous system has not fully developed yet, and it is more likely to experience high fever or a rapid increase in temperature after fever subsides. Brain diseases accompanied by high fever are likely to be severe cases, and most children are caused by brain inflammation, urinary system or lung infections. In addition, for children with unexplained moderate body temperature rise and inability to identify the source or cause of infection in a short period of time, it should not be arbitrarily identified as central fever.
What should I do if my child has recurrent fever
1. Below 38 ℃: Physical cooling
When the child's body temperature does not exceed 38 degrees Celsius, medication is not necessary, and physical therapy can be used. Common physical therapies include drinking plenty of plain water, taking warm baths, and applying antipyretic patches, which can effectively lower body temperature.
2.38 ℃~39 ℃: Drug therapy
At this point, parents need to constantly monitor their baby's physical signs in order to receive timely treatment. For pediatric patients, if their body temperature is above 38 ℃, medication treatment is necessary, and safe pediatric medications should be chosen for their medication. Children with recurrent fever, as mentioned earlier, are mostly caused by infection. If the pathogen is not cleared, even if physical cooling causes the body temperature to drop, it will quickly rise again. At this time, the key is to "treat both the symptoms and prevent recurrence".
3. Exceeding 39 ℃: Doctor's guidance on medication
When the body temperature of a child exceeds 39 degrees Celsius, they are in the stage of high fever and need to be treated with a combination of Chinese and Western medicine. This can reduce the amount of Western medicine taken, thereby reducing damage to the child's liver and kidneys, quickly reducing fever, and treating both symptoms and root causes to prevent the baby from having recurrent fever. Parents should be aware that some babies' medication must be taken under the professional advice of a doctor, and special attention should be paid to the dosage of medication. In addition, it is necessary to promptly send them to the hospital for treatment.
