The basic treatment for intestinal obstruction is gastrointestinal decompression. The purpose of using gastrointestinal decompression includes two aspects: First, nausea and vomiting will occur in intestinal obstruction. Secondly, if the patient has severe nausea and vomiting, it may cause pancreatic tear or even serious gastrointestinal bleeding, after using gastrointestinal decompression, it can effectively avoid the possibility of pancreatic tear brought by nausea and vomiting. In addition to basic treatment of gastrointestinal decompression, adequate rehydration and even anti-infection treatment are needed to prevent bacterial infection, while the cause of the disease should be identified in a timely manner, and surgery is needed if conservative treatment is ineffective. In addition, intestinal obstruction needs to be highly alert to strangulated intestinal obstruction, which may cause intestinal necrosis or even toxic shock and endanger life if not operated in time.
