What are the diagnostic methods for diarrhea in children?

What are the differential diagnosis methods for diarrhea in infants and young children? We should learn more about this issue. In fact, pediatric diarrhea has a great impact on the baby's body. I hope parents will not take this disease lightly. The following will introduce in detail the identification and diagnosis of pediatric diarrhea.

Differentiation and diagnosis:

1. Bacillary dysentery Infants with dysentery often have atypical symptoms. There is often no blood or pus in the stool, and the clinical manifestations are general diarrhea, which is difficult to identify. Attention should be paid to the epidemic situation, and the contact history can often be asked. The child often cries before defecation, indicating tenesmus. Careful observation shows that the child has frequent bowel movements, but the amount is not large each time. Sometimes pus and blood can be seen in the watery stool, and there are more pus cells, red blood cells and macrophages under the microscope. Escherichia coli enteritis has a large amount of stool each time, and some can reach more than 20ml each time. Mucus is common in the stool, but there is very little thick pus, and occasionally there are a few white blood cells and red blood cells, which should be cultured for identification.

2. The onset of infantile hemorrhagic enteritis is the same as that of Escherichia coli enteritis, but after treatment, the diarrhea continues and the condition worsens, with severe abdominal distension, high fever, frequent vomiting, and coffee-like vomiting in severe cases. The stool is watery in the early stage, and the occult blood test is negative. Later, typical dark red jam-like stool appears. Severe dehydration may cause shock in the early stage. Severe poisoning symptoms may cause coma and convulsions.

3. "Physiological diarrhea" Children with exudative constitution may begin to excrete yellow-green loose stools soon after birth, with frequent bowel movements, but without vomiting, good appetite, and normal weight gain. After adding complementary foods, the bowel movements will naturally return to normal.
