The conditions for removing the nasal feeding tube must wait until the gastrointestinal function is restored, i.e., after the clinical normalization of anal defecation and the absence of obvious abdominal distension, nausea, and vomiting sensation. The presence of nasal feeding tube can ensure the nutritional status of patients and provide dietary protection for the recovery of physical function. It is mainly used for patients with gastrointestinal diseases, such as acute pancreatitis or gastric cancer. An intraoperative nasal feeding tube can be left in place to help minimize bloating and nutritional input. After the doctor gave the patient a physical examination, the gastrointestinal function was restored, there were no intestinal peristaltic waves and active bowel sounds in the abdomen, and there was no obvious bloating, nausea and vomiting sensation after. The nasal feeding tube can be removed only after the laboratory indexes are qualified and the blood routine and biochemical functions are normal. The specific removal of nasal feeding tube also needs to be evaluated and judged according to the specific situation. After the tube is removed, continued observation is needed. If there is any discomfort, the patient should cooperate with the doctor for prompt treatment.
