With the exception of the presence of oral mucosa and esophageal burns, patients are able to eat after burns. Increased metabolism of the organism and continuous tissue depletion characterize the severe burn response, and generally speaking, the more severe the burn, the greater the likelihood of nutritional disorders. Malnutrition can delay wound healing, reduce the body’s immune function, further weaken the ability to resist infection and tissue repair, and seriously affect the prognosis. Therefore, for patients with severe burns, adequate and reasonable nutritional support is an important therapeutic measure to improve the healing rate of burn patients, reduce complications and shorten the course of the disease. Oral supplementation is not only economical and convenient, but also has a complete nutrient composition and can promote appetite and gastrointestinal peristalsis. In patients without other medical conditions and treatment contraindications, oral intake should be encouraged as much as possible, and the following points should be noted: (1) For patients with severe burns, the diet should be started with a small number of trial meals and gradually increased to avoid acute gastric dilatation and diarrhea. (2) Patients with residual food in the stomach before the burn, do not eat for the time being, and eat after the recovery of gastrointestinal peristaltic function on the second to third day after the injury, starting with 40~80ml 3~4 times a day, and gradually increasing the amount later. (3) Patients with early burns should have a light and easily digestible diet; patients with late burns should eat more high-calorie, high-protein, high quality, small volume, easily digestible and absorbable food, and increase eggs, fish, meat, etc.
