对危重症病人来说,维持机体水、电解质平衡为第一需要。重症病人的营养支持应尽早开始目前已形成一种共识。随着临床营养支持的发展,营养支持方式已主要为通过鼻胃/鼻空肠导管或胃/肠造口途径为主的肠内营养支持(enteral nutrition,EN)。肠内营养是简便、便宜且更有效的营养方式,因为肠道通路供给自然,细菌的定植及转移更少[1]。 For critically ill patients, maintaining body water, electrolyte balance is the first need. Nutritional support for critically ill patients should start as soon as possible There has been a consensus so far. With the development of clinical nutritional support, nutritional support has mainly been enteral nutrition (EN) through the nasogastric / naso-jejunal catheter or the stomach / enterostoma route. Enteral nutrition is a simple, inexpensive and more effective way of nourishing because of the natural supply of gut access and fewer bacterial colonization and metastasis [1].
