Gastric tube can be removed on its own, but the indications for removal of gastric tube need to be clarified before removal. Generally, if it is gastrointestinal decompression, most of them are for reducing abdominal distension, slowing down intestinal obstruction or some fluids in the gastric cavity, as long as the symptoms are relieved and there is no obvious abdominal distension and abdominal pain, it can be removed. Of course, for nutritional injection through the gastric tube, which is also known as nasal nutrition, according to the specific nutritional status, it can be pulled out if full recovery has been achieved. Gastric tube enters into the gastric cavity through the nasal cavity, through the esophagus at the head end, and discharges some gastric acid and bile from the gastric cavity to the outside of the body through negative pressure attraction, and the head end does not have any other characteristics of the balloon. Therefore, there is no obvious technique for removing the gastric tube in general, as long as it is removed gently and slowly, preventing any violence as much as possible, and if there is obvious resistance, do not exert too much force as much as possible.
