How to diagnose intestinal infarction in children

Pediatric intestinal infarction is a relatively common pediatric disease. Many parents miss the best time for treatment because they fail to discover this condition in time, and also cause their children to suffer a lot. Parents should pay more attention to their children's physical condition. After all, sometimes children may not be able to express themselves well. So how do you diagnose intestinal obstruction in children? Here we will introduce to people how to diagnose intestinal obstruction in children.

Laboratory tests:

1. Hemoglobin and white blood cell counts are normal in the early stages of intestinal obstruction. If the obstruction lasts for a long time and signs of dehydration appear, hemoconcentration and leukocytosis may occur. An increase in white blood cells accompanied by a left shift indicates the presence of intestinal strangulation.

2. The determination of serum electrolytes (K, Na, Cl-), carbon dioxide binding capacity, blood gas analysis, urea nitrogen, and hematocrit are all important. Used to determine dehydration and electrolyte imbalance. and guide the administration of fluids.

3. The determination of serum inorganic phosphorus, creatine kinase and isoenzymes is of great significance for the diagnosis of strangulated intestinal obstruction. Many experiments have shown that when the intestinal wall is ischemic and necrotic, the levels of inorganic phosphorus and creatine kinase in the blood increase.

Other auxiliary examinations:

1. X-ray examination X-ray examination is very important for the diagnosis of intestinal obstruction. After the jejunum and ileum are filled with gas, their X-ray images have their own characteristics: the jejunal mucosal folds are arranged in parallel to the mesenteric edge in a herringbone shape, and their gaps are regular like a spring; the ileal mucosal folds disappear, and the outline of the intestinal tube is smooth; the colon distension is located around the abdomen, showing a colon bag shape.

X-ray manifestations of small intestinal obstruction: gas accumulation, fluid accumulation and intestinal dilatation above the obstruction. After obstruction, fluid appears in the intestinal cavity quickly. The longer the obstruction, the higher the fluid level. The fluid level is higher in low-lying obstructions. The fluid level usually appears 5 to 6 hours after obstruction. Standing examination reveals fluid levels of varying lengths in a ladder-like pattern. During the supine examination, the distribution of the bloated intestinal loops can be seen, with the small intestine in the center and the colon occupying the periphery of the abdomen. In high jejunal obstruction, a large amount of gas and fluid appears in the stomach. In case of low small intestinal obstruction, the fluid level is higher. In complete obstruction, there is no gas or only a small amount of gas in the colon.

First of all, the patient should be taken for an X-ray examination. This examination is very important for the diagnosis of intestinal obstruction. If this examination is not done, it will be difficult to confirm the cause of intestinal obstruction. Only this project can clearly see the condition of the patient's intestines. Not only that, blood tests should also be done, such as hemoglobin tests, which are also very important.
