Fever is one of the most common reasons for children to visit the hospital. When a child has a fever, parents are anxious and rush to the hospital, and some even make a fuss and disrupt the medical order because their child cannot be seen in time for a fever. The most common and ridiculous reason for parents is that they are afraid that their child’s fever will “burn their brains out”! That whoever’s baby, silly four years old still can not speak, is a child fever burned brain. So, fever will really “burn the brain”? First, think about the story of “beacon fire” In ancient times, there was no telephone and no network, beacon is an important military defense measures. The beacon towers were connected, when the foreign enemy invaded, people lit wolf smoke on the beacon towers at daytime and bonfires at night, and the neighboring beacon towers saw the smoke and fire, and immediately lit up the smoke and fire in this station, so that one to pass one, the news of the foreign enemy invasion to the capital. Imagine, the capital received the news is to pay close attention to the scale and movement of the enemy and mobilize troops to deploy a strategy to fight, or quickly dispatch troops and generals to the beacon fires to extinguish? If the country is unfortunately defeated and lost, is it defeated to the invading foreign enemy or defeated to the wolf smoke bonfire on the beacon? The answer is self-explanatory. Fever can be big or small, the focus is on the observation of the disease Second, fever is a symptom, the disease itself is the root Fever is the story of the “beacon fire”, fever is not a “disease”, when various pathogens such as bacteria, viruses, mycoplasma, etc. invade the body (cold, pneumonia, enteritis, etc.), or When various pathogens such as bacteria, viruses, mycoplasma, etc. invade the body (flu, pneumonia, enteritis, etc.), or when diseases such as tumors and connective tissue diseases appear, the operation of our body becomes impaired and various abnormalities occur, of which fever is a common manifestation. Fever is only one of the external manifestations of these diseases, and is a phenomenon and symptom of the disease. In the case of central nervous system infections, such as viral encephalitis and septic meningitis, fever and other manifestations can occur and may leave neurological sequelae, such as cerebral palsy, intellectual backwardness, and limb movement disorders. However, we should think clearly that it is not the “fever” itself that causes “brain damage”, but the disease itself, such as encephalitis and meningitis, that causes the fever and “brain damage”. Both fever and “brain damage” are the result of the disease itself. The fever itself will not burn other organs or tissues such as lungs, it is the disease itself such as pneumonia that causes the fever, not the fever that causes pneumonia. The fever can be big or small, and the focus is on the observation of the condition. There are various diseases that cause fever, some heavy and some light, such as the common cold in mild cases, and leukemia, myocarditis, meningitis, sepsis in heavy cases. In most cases, fever is caused by mild illnesses such as colds. However, it should be noted that other serious illnesses such as pneumonia, encephalitis, meningitis, and myocarditis also usually present early as only cold symptoms. We repeatedly emphasize that it is important to focus not only on the symptom of fever, but also on the length of fever, diet, eyes, activity, circulation, respiration and mental status, and so on. Especially mental status, if fever is accompanied by poor mental response, abnormal body movements, wandering eyes, florid skin patterns, bleeding spots, severe headache and vomiting, shortness of breath, wheezing, convulsions and other symptoms and manifestations of serious diseases, it needs to be taken seriously and promptly consulted, or if there are other uncertain conditions also promptly consulted. It is also recommended that infants under 3 months of age with any degree of fever seek medical attention as soon as possible. Remember, when there is wolf smoke at the border, you should closely observe the foreign enemy’s strategy to deploy against the enemy, and don’t just think about putting out the wolf smoke. Since fever itself does not “burn the brain” and does not burn any other organs, fever is not a disease, but only one of the manifestations of the disease, then Fever medicine is only symptomatic treatment rather than causal treatment, that is, fever medicine is only a “cure” but not a “cure”. In fact, the purpose of reducing fever is not to reduce fever for the sake of reducing fever, but to relieve the child’s discomfort and alleviate the discomfort caused by fever. Therefore, even if the child’s body temperature is still high after taking antipyretic drugs, but the child’s dizziness, headache, fatigue, poor appetite and other symptoms are relieved, then the purpose of antipyretic drugs is achieved. In fact, the blind pursuit of normal body temperature is only to cure the “heart disease” of parents. Therefore, antipyretic drugs only relieve the symptoms, even if the child does not have a fever after using the drug, we should pay more attention to observe whether there are other symptoms manifested, and seek medical attention in a timely manner.
