Baby to the hospital checkup doctors often open laboratory tests, the most common of which is routine blood, then routine blood is really necessary, really as some people think is the doctor open in order to earn money, the following I first on the routine blood report as an example to popularize science knowledge, routine blood report is relatively large amount of information, I am here to commonly used the main indicators extracted from the exchange of communication. Please see the following pictures First of all, the white blood cell count, (cell phone to write something not aspect, I only on the picture of the value of the introduction, count units and so omitted, later have time to use the computer to slowly modify). The reference range on the test sheet is for adults, and here we will focus on how to look at the blood count of children. The white blood cells of babies born in the range of 15 to 20, peak at 6 to 12 hours, fall to an average of 12 in about a week, and then slowly maintain at about 10, close to the adult level after the age of 8. Leukocyte classification information is more important, 4 to 6 days of birth of 4 to 6 years lymphocyte-dominated, about 65%, neutrophil ratio of about 35%, the rest of the time should be exactly the opposite, that is, neutrophil-dominated, if the ratio is not in this range, that is, the lymphocyte-dominated period neutrophil-dominated, such as 7 days of the baby’s blood routine neutrophil ratio of 60% or even higher, coupled with a refusal of breast milk, the The first thing you need to consider is that this may be due to bacterial infections, and bacterial infections should be treated with antibiotics, or else antibiotics should be used with caution, and children are commonly used antibiotics for bacterial infections such as penicillin and cephalosporins, macrolides for mycoplasma infections such as azithromycin, and fungal infections such as fluconazole or mycoplasma, which type needs to be used Let your doctor evaluate the type of antibiotics you want to use, not the high white blood cells, and caution parents not to abuse antibiotics. Many parents and friends feel that the higher the white blood cells the worse, is not the lower the better it is, I will introduce the following aspects of granulocytopenia: for children with white blood cells below 4 or absolute value of intergranulocyte cells i.e. absolute value of granulocytes below 1.5 is usually considered granulocytopenia. Granulocytes are equivalent to the army of a country, representing the external defense, the lower the defense, the worse. By the way, a brief description of the grading, mild 1.0 to 1.5; moderate 0.5 to 1.0; severe less than 0.5. what causes granulocytopenia, common causes are infections, such as viral or bacterial infections; drugs such as antipyretics or certain antibiotics, so in general it is recommended that under two years of age, especially within six months easily do not use cold medicines such as aminoglutethimide and other cold medicines, which There are acetaminophen and other antipyretic ingredients, some babies are prone to granulocytopenia, etc.; unexplained temporary granulocytopenia; hematologic lesions, etc. Mild unexplained granulocytopenia, if the baby does not have how abnormal performance can prevent cold and flu, pay attention to observation, appropriate more warm water, avoid contact with sick people, avoid going to densely populated places, etc., to prevention, regular re-examination; moderate or above, it is recommended to find the cause, treatment of the original disease, with granulocyte drugs such as Western medicine shark liver alcohol, Ricogun tablets, Chinese medicine to supplement the white granules, Diyu In severe cases, in addition to the active treatment of the primary disease, it is also recommended to inject granulocytes, i.e. recombinant human granulocyte colony-stimulating factor injection. Most of the eosinophils have the same meaning as eosinophils, but they are of little significance to children, so they are not introduced. Eosinophils are mostly found in allergic lesions such as eczema, urticaria, allergic rhinitis, allergic cough and other allergens. If there are parasitic infections, it is necessary to use worming medication, commonly used worming medication are intestinal wormer and Baota sugar, but the side effects are less recommended intestinal wormer, in general, within two years of age is not recommended worming. Monocytes are influenced by too many factors, so space is limited here not to make a special introduction, most children represent immunity, immune activation when the disease, that is, the immune response, will appear monocyte increase, if the exponential increase, that is, the increase is more obvious need further examination such as cytological morphology, usually check the peripheral blood cytology morphology, bone penetration to check the bone marrow cytology morphology. Erythrocytes and classification The role of erythrocytes is mainly gas exchange, the oxygen absorbed by the lungs and carbon dioxide produced through the entire blood circulation for the exchange of various organs; carry immune factors and participate in the immune response themselves. It is mainly generated through the supply of iron, vitamin B12, folic acid, etc. Why many babies are discharged from the hospital with iron supplements such as Philco or Elle Iron? I will briefly introduce the general knowledge of red blood cells. Erythrocytosis involves erythrocytosis, which is not highlighted here and will be talked about later when I have the chance, but mainly to talk to you about anemia. There are many causes of anemia, such as abnormalities in the red blood cell membrane, enzyme defects, etc. These are more specialized and not the focus, and those involved in these are often treated poorly with early intervention, so your doctor will tell you that you need further tests to confirm the diagnosis. Here I will mainly talk about the most common malnutrition anemia, which is the most common phenomenon in newborns and infants, especially premature babies. The red blood cells of newborn babies are 5 to 7, and the hemoglobin is 150 to 170. A value lower than this within a week after birth indicates anemia, and the short life span of red blood cells in newborns is about 80 days, plus the destruction of red blood cells due to postnatal stress and birth injuries, which can easily cause jaundice and anemia, especially in premature babies. However, some babies are malnourished, serious infections and other causes of malnutrition anemia is more serious, need timely examination and treatment, so when discharged from the hospital anemia obvious baby, especially premature babies most of them will let go back to the United States imported Philco or El iron supplement iron and vitamin C, Philco high iron content, affordable, most recommend this, large babies with good digestive function can also choose Ferrous sulfate, etc., the general iron is easy to cause digestive system reactions such as vomiting, need to be taken orally half an hour before meals. Because of the heavy anemia in preterm babies, the knowledge of red blood cells will be opened again. The above is mainly about red blood cells and hemoglobin, the length is long, the cell phone is not good to write, and then continue a paragraph. The anemia is classified as anemia within 28 days, below 145 hemoglobin, 120 to 144 mild anemia, 90 to 120 moderate anemia, 60 to 90 severe anemia, 1 to 4 months below 90 anemia, 4 to 6 months below 100 anemia, physiological anemia or other, judged by red blood cell pressure, specific volume, etc., see the table below Platelets Platelets normal value 150 to 300, platelet reduction Decreased platelets and increased platelets can easily cause bleeding disorders, and the cause needs to be identified and treated accordingly. Most of the abnormalities in this area need to be judged by the doctor in conjunction with the baby’s condition. The ones that are of great reference significance are introduced, while the ones that are not introduced are of little reference significance or need to be evaluated by a doctor.
