Critically ill patients with high-risk nutrition are often at risk of refeeding syndrome(RFS), that the incidence of RFS is as high as 30-50%. It is sure that patients with refeeding syndrome were treated with restrictive enteral nutrition, but the definition of refeeding syndrome is not uniform, and there is still a lack of awareness high-risk patients of RFS to receiving early empirical low-calorie feeding intervention. So, we designed the study which is divided into three stages. Firstly, the monitoring rate of RFS was reviewed to evaluate the incidence of RFS in general ICU. Secondly, the best diagnostic criteria of RFS were prospectively defined. Finally, on this basis, it is assessed whether early low-calorie feeding could improve prognosis in high-risk patients with RFS.
