People are concerned about their diet, and I believe everyone is concerned about their diet. As a neurosurgical patient, a reasonable diet is directly related to the patient’s recovery process. Here, we can only make some principle reminders due to the limitation of space. First of all, during the acute phase of the disease (whether it is trauma, stroke, or early postoperative period), the patient’s digestive ability is relatively weak, so the food should be relatively light, such as porridge with some salt, rice soup, rice paste, etc., from little to much, eat more meals, and comatose patients may need to be fed with a nasogastric tube. Three to four meals a day, not the more the better, the patient can not digest and absorb more is also a waste. Secondly, in the middle and late stage of the disease, that is, the recovery period after stabilization, as the patient’s condition improves and the digestive ability recovers, the food should be gradually increased with more nutritious food, such as milk powder, soy milk, eggs, broth, fish, chicken, vegetables, fruits, etc., to supplement the nutritional loss caused by trauma and promote the patient’s recovery, but the premise is that the patient’s needs and digestive and absorption functions should determine the food to be eaten. However, the premise is that it depends on the patient’s needs and digestion and absorption function to decide the type of food and the number of meals to eat, not the more the better.
