[Prevention and management of refeeding syndrome in patients with chronic critical illness]

Nutritional support is an important means to treat the patients with chronic critical illness for commonly associated malnutrition. Refeeding syndrome is a serious complication during the process, mainly manifested as severe electrolyte with hypophosphataemia being the most common. Refeeding syndrome is not uncommon but it is often ignored. In our future clinical work, we need to recognize this chinical situation and use preventative and treatment measures. According to NICE clinical nutrition guideline, we discussed the risk factors, treatment methods and preventive measures of refeeding syndrome in patients with chronic critical illness. We argued that for patients with high risk refeeding syndrome, nutritional support treatment should be initially low calorie and slowly increased to complete requirement. Circulation capacity should be recovered, fluid balance must be closely monitored and supplement of vitamins, microelement, electrolytes should be noted. After the emergence of refeeding syndrome, we should reduce or even stop the calorie intake, give an active treatment for electrolyte disorder, provide vitamin B, and maintain the functions of multiple organs.
