1. 6 hours after waking up without swallowing disorder, a small amount of liquid diet can be fed, and then gradually changed to soft food. 2. Patients with persistent coma and swallowing dysfunction for 24 hours after surgery should be fed nasal fluid diet, and nasal feeding should pay attention to: ① High calorie, high protein, high nutrition and low salt diet is recommended. Avoid the retention of sodium ions in the body can cause an increase in blood pressure, which in turn causes an increase in intracranial pressure. Ensure the patient’s nutrition, which is beneficial to the recovery of postoperative tissues. ②Temperature 38-40 degrees to prevent scalding of the patient. ③Small and frequent meals, less than 200 ml each time, with intervals greater than 2 hours to prevent indigestion. ④Elevate the head of the bed 15-30 degrees, and do not change the patient’s position for half an hour after fasting to prevent food reflux. ⑤Prove that the nasal feeding tube is indeed in the stomach before feeding. ⑥Prevent the gastric tube from being dislodged. The injection of food when the gastric tube is dislodged can cause food to enter the respiratory tract and cause asphyxia, so it should be properly fixed and not pulled out by itself. (7) When the gastrointestinal function is not fully recovered in the early post-surgery period, gas-producing foods such as milk and sugar should be introduced as little as possible to prevent intestinal distension. If the convulsion of coffee-colored liquid suggests intra-intestinal bleeding in the gastrointestinal tract, temporary fasting or infusion of water quality should be done to stop bleeding before eating. More evidence from epidemiological and laboratory studies is needed to determine the relationship between dietary factors and the occurrence of glioma. However, preliminary trial results suggest that a diet rich in vegetables and fruits has a protective effect on glioma patients. Carrots, which are rich in carotenoids, and tomatoes, oranges, apples and other vegetables, which are rich in vitamins, have been negatively associated with glioma development. The consumption of processed and preserved fish, cheese and other meat products has been linked to brain tumors, while cooked ham, processed pork chops and fried bacon are likely to induce tumors.
