Children with colds and fevers, especially high fever persists, parents are very anxious, want to immediately reduce the fever, otherwise they do not trust the doctor. As a child’s parents, always hope that the child’s disease quickly; as a doctor, also hope that their own hands to treat the patient, can be the fastest speed to heal. So, we are all brainstorming, in addition to choosing the most effective drugs, is to choose the most effective way to use drugs. However, there is a saying that “the quickest way is the slowest way”. There is a process of illness and recovery. If your doctor determines that you only have a cold that you can tolerate, it is best not to rush into taking antipyretics. Fever is one of the body’s mechanisms for fighting infection. Our body mobilizes its defenses to kill foreign germs by raising its temperature (generally, germs die at 39°C or higher), thus shortening the duration of illness and increasing the effectiveness of antibiotics. If you use medication to reduce fever at the beginning of a cold (37-38.5°C), it will temporarily turn the bacteria in your body into a pseudo-dead state and cause them to become resistant to medication, which is often more difficult to treat once the die-off occurs. There are many causes of fever, and most of the fever in infants and young children are viruses, bacteria, mycoplasma and other pathogens caused by infectious fever, got a cold, bronchitis, pneumonia, bacillary dysentery, enteritis, urinary tract infections when the performance of the fever are infectious fever. Infectious fever is not the same pathogen, if it is caused by bacteria or mycoplasma, you can choose the appropriate antibacterial drugs; if it is caused by viruses, antibacterial drugs do not work. When the fever, the most important thing is to find out the disease that caused the fever, and as far as possible to determine which pathogen, in order to achieve the best therapeutic effect. Studies have shown that 90% of colds are caused by viruses. Therefore, you should not take antipyretic injections without identifying the cause of the fever. In the case of the most common cold, the virus reproduces fastest at 37 degrees Celsius, and dies easily when the body has a high fever. From this we can see that fever is a means for the body to fight the virus. Casual use of antipyretic drugs, but also may produce the following bad consequences: disturb the heat pattern, resulting in the illusion of disease, delayed diagnosis; a lot of sweating, so that the loss of body fluids; suffering from enterocolitis, bacillary dysentery, it is very easy to get dehydrated, because of the fever and then the use of antipyretic drugs, more heavy dehydration. According to foreign pediatric experts reported that children with antipyretics will prolong the course of viral diseases. Infants and young children, because the development of the nervous system is not yet complete, in order to prevent high fever and stroke, it is possible to take antipyretic tablets once in a while when the fever is high, such as repeated use of antipyretic drugs or antipyretic injections because of the fever that does not go away, obviously the harm outweighs the good, and is not desirable. The accurate way to deal with high fever emergency is to let the child rest in bed and drink plenty of boiled water. It is best to give the child a light, easily digestible liquid food. In the active control of the system of infection, basically, in accordance with the doctor’s instructions accurately choose antipyretic drugs, with physical cooling such as warm water bath, etc., the temperature of the water 32 ~ 34 ° c is more appropriate, each time to wipe the time of more than 10 minutes. Parts of the neck, thigh roots, armpits, palms, feet, etc., should pay attention to high fever, do not use alcohol to rub the body. Because alcohol evaporates too quickly, it may cause cramps. Forehead can put a cool towel compress. Some parents bring fever baby to the hospital to see a doctor, to the child wrapped in three layers outside three layers, the doctor looked at the parents let the child immediately take off two pieces of clothing. Because, to the fever child wearing too many clothes is not conducive to body temperature dissipation. Of course, the baby fever, parents do not have to fuss, but also can not be taken lightly, resulting in unmanageable condition. Baby fever pathology can be big or small, serious sepsis, encephalitis, meningitis, myocarditis, etc., do not deal with will lead to disability or death; light just a slight cold, ignore it will also be good on its own. But the difference between the non-professionals is difficult to judge, and sometimes it is necessary to use testing technology to really differentiate. Baby fever, the first physical methods to lower the temperature, if the temperature exceeds 38.5 ℃, before the use of drugs to lower the temperature. In the use of drugs to lower the temperature at the same time, but also with physical cooling. At the same time, parents should learn to observe small children with fever will be combined with other manifestations: such as rapid heartbeat, breathing faster, the body feels extremely uncomfortable, loss of appetite and general weakness, the phenomenon of a young baby will not speak, and even become restless crying and restlessness. At this time, moderate treatment, so that the body temperature is not too high is reasonable, especially with a history of febrile convulsions or congenital heart disease in infants and young children, but also the need to consult a doctor in a timely manner.
