Necessity of Diarrhea Examination in Children

Drawing blood is a necessary means to check various diseases. Doctors can make a more accurate diagnosis of the patient's condition from the various numerical analyses of the blood. If the condition of infants and young children with pediatric diarrhea is serious, parents will send their children to the hospital. Many parents have a misunderstanding that the child only has diarrhea and it is enough to check the stool, not the blood. The child is too young, and diarrhea has a great impact on his body. At this time, blood drawing is still necessary, which makes some parents have a certain resistance.

Let's briefly introduce the blood test items so that parents can roughly understand the necessity of blood tests. Blood tests are usually divided into: blood routine, six blood biochemical tests, and electrocardiogram.

1. Blood leukocyte count and classification: The total leukocyte count generally does not increase in viral enteritis, but may or may not increase in bacterial enteritis. More than half of the children have increased band nuclei, with the percentage of band nuclei exceeding 10%, which is helpful for the diagnosis of bacterial infection.

2. Blood culture: It is of diagnostic significance for bacterial dysentery, Escherichia coli, Salmonella and other bacterial enteritis. Positive blood bacterial culture is helpful for diagnosis.

3. Blood biochemical examination: For children with severe diarrhea, blood pH, carbon dioxide binding capacity, bicarbonate, blood sodium, blood potassium, blood chloride, and blood osmotic pressure should be checked in time, which are of great significance for diagnosis and treatment.

4. Electrocardiogram: Patients with hypokalemia should undergo electrocardiogram examination; patients with prolonged disease course, nutritional disorders and severe symptoms of infection and poisoning should undergo X-ray and B-ultrasound examinations. Electrocardiogram examination of patients with hypokalemia shows flat T waves, bidirectional or inverted T waves and the presence of U waves.

In fact, when children suffer from pediatric diarrhea, not only will some values ​​in the stool change, but the values ​​in the blood test analysis will also be very different. Doctors can find out the cause of the child's illness and make targeted treatment diagnoses by comparing the values ​​of the test results with the standard values. I hope that parents and children will not be deterred from blood draws after knowing the situation, but treat it rationally so that children can get treatment faster.
