摘要
“肠实质与（或）功能的损害，导致消化、吸收营养与（或）屏障功能发生严重障碍”定义为肠功能障碍。应激状态下．胃肠道参与了机体的病理生理改变．被认为是“机体应激的中心器官”。危重症时．由于缺血、缺氧、代谢紊乱，患者常合并有胃肠道功能障碍．这也常常成为治疗危重症的一个难点。无疑，营养支持对肠功能障碍是一项不可或缺的治疗措施，但实施有一定困难。本文主要就胃肠道功能障碍的概念、病因及胃肠道功能障碍时患者营养状态的评估，营养支持方案的制定及实施作一阐述。
Gut dysfunction is defined as the impairment of intestinal parenehyma and（or） intestinal function leading to dyspepsia, malabsorption, and （or） intestinal barrier dysfunction. In the stress state, gastrointestinal tract contributes to the physiopathological change, which is considered as the ＂central organ after stress＂. Because of ischemia, anoxia and metabolic disturbance, critical illness is frequently complicated with intestinal dysflmction, which is one of the difficulties to treat critically ill patients. Undoubtedly, nutritional support is one of the indispensable therapies of intestinal dysfunction, which is also difficult to manage. This report was aimed to elaborate the definition, causes of intestinal dysfunction, assessment of nutritional status, and design of nutritional support in these patients.
