Why should the blood be drawn if the child has a fever! As soon as the child has a fever, the doctor

The blood test is to see if the baby has inflammation, and now the hospital will be like this, and it is really sad to see the baby crying when he pokes his fingers.

Check the cause of the fever, and see if there is an indicator that is low or not, it seems to be lymphatic or something.

I'm afraid it's the virus, so I checked the blood, and I always asked you to check this and that when you go to the hospital, you'd better cool down yourself first when the baby is not a high fever.

The child's immunity is relatively low, when the weather is cold or because of some other factors, it will cause the child to have a fever, I don't know if you have observed, when the child goes to the hospital with a fever, the doctor first asks the child to check a blood routine, and then I will introduce the reasons for this.

First of all, we must know that the doctor must have his purpose in prescribing a blood test, first of all, the blood test is to determine whether the child has some infectious diseases, the most common infection is bacterial infection and viral infection, if the child is a viral infection, then you need to prescribe some antiviral drugs to the baby, if it is a bacterial infection, then you have to add some antibiotics to the baby. Therefore, the doctor began to have a routine examination, is to check whether there are some other substances in the blood by checking the child's blood, whether there is an infection, once the child has a bacterial infection or a viral infection, the impact on the child is still very large, usually the time of infection is also very long, the child in the process of illness is not only low immunity, at the same time has no spirit, is not interested in everything around him, especially no appetite, The impact on children is still very large, so parents should always pay attention to their children's health in life.

It can be seen that once a child has a fever and a cold, it is still very harmful to himself, so parents should always pay attention to their children's physical health in life, and remember to dress their children when it is cold.

Especially the child is a more active, in life may often play with other children, this time may be once the heat will take off the clothes, so that there will be cold and fever symptoms, parents must pay attention to avoid the occurrence of these situations, otherwise once it happens, the impact on the child is still very large.

Fever in children is more common when there is an inflammatory reaction after the invasion of pathogens such as viruses, bacteria, mycoplasma, chlamydia, and rickettsia. Different pathogens cause the changes in the blood cells of the child's blood routine to change the various numerical indicators, and have their own corresponding characteristics.

Therefore, at this time, the purpose of the blood test is to clarify the severity of the inflammatory reaction in the child's body at this time, as well as to understand the nutritional status of the body. Clarify the condition and **, and target the symptoms** and **.

Your child's persistent fever may be caused by an infection inside the body. Routine blood tests can be done to identify lesions by observing various indicators. Parents must cooperate with the doctor.

The main reason is that doctors need to rule out the possibility of bacterial infection through blood tests, so that they can make a more accurate diagnosis**.

Fever in infants and young children is very common, whenever a child has a fever, especially a high fever, parents are usually very anxious and will take their children to the hospital, the first step, the doctor will ask for a blood test. It is to be able to judge the cause of the disease through the results of the blood test, so as to use the medicine in a targeted manner, that is, to find the root cause and prescribe the right medicine.

There are several indicators that usually need to be paid attention to in a fever blood test, one is white blood cells, if the white blood cells are high, it is generally a bacterial infection, and the higher the infection, the higher the degree of infection. The second is to look at mesogranulocytes, if the mesogranulocyte value is lower than the normal value, it will be a viral infection. Monocytes, eosinophils, basophils, platelets, C-reactive protein, etc., exceed normal values, which means that there is a certain problem.

If the baby has a fever of more than 38 degrees for several days, the results of the blood test are that the number of monocytes and the number of basophils have increased, which exceeds the normal value, and the percentage of monocytes and C-reactive protein have also exceeded the normal value, and the doctor judges that it is the result of viral infection and bacterial infection. At that time, we were prescribed antibiotics, and the child was also prescribed some fever medicine for coughing.

If antibiotics are used for viral infections, they should be used according to the course of treatment, and if the course of treatment is not enough, then some resistance will develop later.

The child's fever is also a normal response of the body's immune response, which is the result of the immune system fighting against bacteria or viruses, so if the child has a fever, if there is no bacterial or viral infection, it is not recommended to forcibly reduce the fever, if the child's mental state is normal, you can not reduce the fever, if the fever has reached the point of affecting the child's mental state, you should use antipyretics.

If the white blood cells are high and neutrophils and platelets are high, it means that it is a bacterial infection and cephalosporin antibiotics are needed, and if the neutrophils are high and the white blood cells are not high, it should be mycoplasma infection. Need to use azithromycin, or roxithromycin, the right medicine to get rid of the disease, now doctors are very cautious in prescribing drugs, children are sick parents are anxious to burn, doctors have to wait for the results of the test, will not rely on experience or speculation to use the drug.

Because the blood test can see whether the child has a lesion, it can also see what is wrong with the child, because there are many diseases with fever symptoms, so the blood test will be required.

Because blood is very important for a person and will also reflect whether a person's body is healthy or not, children with fever should have a blood test first.

Because the child has a fever, it is likely that the respiratory system is infected with a disease, and in order to be diagnosed as soon as possible**, the child must be given a blood test.

You didn't send the specific content of the blood test, and the fever patients mainly looked at the number of WBC, the percentage of neutrophils, and the percentage of lymphocytes, which are the basis for analyzing viral infection or bacterial infection. In the case you said, we can only guess that it is a viral infection. The percentage of neutrophils in WBC does not exceed that of a viral infection, and that of a bacterial infection occurs after that.

Usually on the **, our principle is that if you can take medicine to cure it, you don't have an injection, if you can get a small needle, don't do it, and if you can do it, don't go under surgery. Now the part of the injection is omitted, mainly because it is too painful to talk about, and some children also cause gluteal contractures and become disabled. The disadvantage of hanging water is that once there is an allergic reaction, it is too late to rescue most of them.

It is best to take oral Chinese patent medicine for children's minor diseases**. There is nothing ***, and it is able to maintain the natural history of the disease. In other words, it can increase the child's own resistance.

If many people like to use hormones and antipyretics to forcibly suppress the body's own resistance, the course of the child's disease will be shortened on the surface, but the disease will still remain in the body, and it is easy to recur and prolong. That's why many children are cured today and have been cured for 2 days.

During illness, pay attention to a light diet and eat a liquid or semi-liquid diet. Do not eat high-protein foods or hair products, such as eggs, as this will cause higher fever.

Pay attention to the room to be quiet, be sure to let the child rest well, the human body repair is carried out in sleep, only after rest can the recovery be fast. The indoor air should be fresh, open the window for ventilation at least 2-3 hours a day, and the quilt should not be too thick and too thick. Drinking more plain water or vegetable juice is conducive to sweating and urination, and promotes the elimination of toxins.

Wipe off the sweat stains on the child's body frequently, and keep it clean and hygienic to avoid catching a cold again. **You can use a little heat clearing and detoxification Chinese patent medicine, such as: children's soybean Qiao granules, antiviral oral liquid, Pudilan anti-inflammatory oral liquid, etc., as long as 1 choice can be selected.

Allowing the disease to heal naturally is the best policy. Usually each illness is about 7 days, which is related to the body's biological clock. Persistence is victory.

90% is viral. But prevent bacterial infections. So antibiotics are also used.

A cold is a self-healing disease, and you will get better.

Adults often don't take medicine or injections, and it's fine for a few months and a half.

Children are afraid of infection, so they need to be treated. If you don't have a fever, don't worry too much, strengthen care.

If you have a fever, take medicine, and use antipyretic medicine for the above.

It is better not to get injections, which are the most dangerous. Take the medicine and take it slowly.

It is still very necessary, the child has a fever and does not know his symptoms, which is not convenient for the doctor to judge the condition, so it can only be judged by other ways, and blood tests are a very common one.

I think it's necessary because a routine blood test can determine what kind of viral infection it is, be able to distinguish between the common cold and the flu, and be able to check all aspects of the child's indicators.

It is necessary so that immune diseases can be avoided in time, and also aggravation of the condition can be avoided. Some factors can also be ruled out.

Do I have to take a blood test if my baby has a fever?A blood test is not necessary for your baby to have a fever.

If it is because of a cold or fever, then the blood routine is not a routine test, that is, the blood routine is not necessary for every cold and fever, especially in the early stage of the disease. Therefore, whether to take a routine blood test or not requires a careful face-to-face consultation by the doctor, a comprehensive detailed medical history and a careful physical examination, depending on the specific situation.

How to lose the potato world science for the baby blood test routine1. Generally speaking, it is of little significance to have a routine blood test within the first 12 hours of a cold or fever.

2. If you consider it to be a cold or only a fever with no other symptoms, and your mental state is fine, give priority to viral infection, then there is no need to rush to test blood routine in the first few days. (If Mom and Dad are really worried, it doesn't hurt to check it out.) )

4. If the fever is more than 3 full days (72 hours), a laboratory blood test can be considered.

5. If the fever is more than 5 full days (120 hours), it is highly recommended to have a routine blood test, and it is necessary to rule out the possibility of other serious diseases.

What is the use of a blood test routine1. To help determine the type of infection, in general, the peripheral blood white blood cell (WBC) count is not high or low, and the lymphocyte count or percentage is high, indicating viral infection; Elevated WBC count and neutrophil count or percentage suggests bacterial infection.

Note:

Peripheral blood white blood cell (WBC) count and neutrophil percentage are one of the traditional screening tools to determine whether it is bacterial infection, but the results cannot be used as absolute criteria.

2. Help assess the risk of disease The decrease or deficiency of neutrophils can be seen in various infections, and may also be secondary to tumors, poisoning or after taking certain drugs, but no matter what the cause, the decrease or deficiency of neutrophils may cause the body's ability to resist bacterial infections to decrease, thus causing serious bacterial infections.

Note:

In addition, there are many other indicators in the blood routine (such as the count and percentage of median cells (three-part method) or monocytes, eosinophils, basophils (five-part method)), etc.), these values have different meanings, and are of great significance for health education and doctors' adjustment of ** programs.

Tips: How to perform effective physical cooling1. Parents should not cover sweat when they have a fever, wear too thick or cover too tightly for the baby, and evaporate water to dissipate heat is the main way, accounting for more than 90%, so blindly covering sweat will affect the heat dissipation guide and cause the body temperature to rise.

2. When the baby's appetite is greatly reduced when there is a fever, drinking less water will lead to dehydration, the mother lets the baby drink more water and eat fruits, and urinate and defecate more to help the baby cool down, but remember not to eat too full.

3. The mother can wipe the baby's ** with warm water to help the baby dissipate heat and reduce the temperature.

4. Keep the room comfortable and cool, remember to open the window for ventilation, and if the weather is hot, you can turn on the air conditioner to cool down.
