Abstract: Nutrition therapy represents one of the most important parts of burn comprehensive treatment and plays a key role in severe burn care, but its curative effect needs to be further improved. With the deepening understanding of body metabolic rules after burn injury, the principle and method of nutrition therapy have been changed. On the one hand, nutrition therapy needs to adapt to the metabolic change post burn. On the other hand, nutrition should regard regulating body metabolism, protecting organ function, and maintaining internal environment stability as the core goals. Hence, some key points such as energy supplement, nutritional opportunity, and nutrition pathway need to be adjusted, in order to improve nutrition efficacy and patient prognosis.
