机体遭受重度烧伤、感染、外科大手术等严重的应激后,出现代谢亢进,能量消耗增加。如果不及时处理可使构成机体的蛋白质丧失,继而引起致命的多脏器衰竭,因此积极地补给营养素有重要意义。但在这种状态下,消化道对营养素的消化,吸收能力也多呈极度降低状态,因此,近年来胃肠外营养法(totalparenteral nutrition:TPN)的营养管理技术有明显发展。由于TPN 补给的营养素之中,以前主要是利用葡萄糖作为能源,可是在严重的应激下机体对葡萄糖利用能力有一定界限,超越此界限虽投与多量葡萄糖作为热量的来源,这非但不能利用,且增大了在末稍组
The body suffered severe burn, infection, surgical major surgery and other serious stress, the emergence of hyper-metabolism, increased energy consumption. If you do not promptly deal with the body can make the loss of protein, which in turn lead to fatal multiple organ failure, so actively providing nutrients of great significance. However, in this state, digestive tract digestion and absorption of nutrients are also mostly reduced state, therefore, in recent years, parenteral nutrition (TPN) nutrition management technology has evidently developed. Due to the nutrients that TPN supplies, glucose is mainly used as energy source before, but under severe stress, the body has a certain limit on the ability of glucose utilization. Exceeding this limit, a large amount of glucose is used as a source of heat, which not only can not be utilized but also Increased in the last group
