Patients with pancreatitis are recommended to have a gastric tube inserted. Patients with pancreatitis not only show abdominal pain and abdominal distension, but also have a combination of nausea, vomiting, anal cessation of exhaustion and defecation. The main reason is that the secretion of pancreatic enzymes causes disorders in the patient’s gastrointestinal function, non-peristalsis of the stomach and intestines, weakening of bowel sounds or disappearance of bowel sounds, etc. A large amount of digestive fluid accumulates inside the gastrointestinal tract, and the patient’s nausea, vomiting, and abdominal distention can aggravate the condition of pancreatitis. It is recommended to insert a gastric tube to reduce the fluid in the gastrointestinal tract, which can effectively reduce the self-digestion or self-injury process of the pancreas. If the patient has very mild symptoms of pancreatitis or is intolerant to gastric tube insertion, elderly patients with great difficulty in gastric tube insertion can also continue to be observed without gastric tube insertion for the time being.
