Acute intestinal obstruction is a very serious acute abdominal condition. When acute intestinal obstruction occurs, the intestinal canal is completely blocked, and above the obstruction, the intestinal contents accumulate dramatically, causing electrolyte disturbance in the whole body. The accumulation of intestinal contents can cause severe dilatation of the intestinal wall, which can lead to ischemia, necrosis and perforation of the intestinal wall, resulting in diffuse peritonitis and infectious shock. In addition, the dilatation of the intestinal canal can lead to an increase in intra-abdominal pressure and diaphragm uplift, resulting in respiratory distress, and can also lead to a decrease in ileocardial blood volume and a decrease in blood pressure. Therefore, the development of acute intestinal obstruction is very fast and may lead to death in a short time in severe cases, so prompt medical attention is needed.
