"Gut injury" and a corresponding impaired gut barrier function are thought to have a high impact on the development of multiple organ failure (MOF) in the critically ill. Mucosal lesions and increased intestinal permeability can provoke translocation of bacteria and endotoxins and initiate local and/or systemic immune-inflammatory response, bearing the risk of development of multiple organ failure. Enteral nutrition using the physiological pathway provides the intestinal mucosa with nutrients, which is thought to reduce bacterial translocation and septic complications. ⋯ Although only little data from randomised trials are available, enteral nutrition has advantages and is cheaper than total parenteral nutrition. In the critically ill, the goal of enteral feeding is not coverage of total caloric requirements, but continuous administration of at least a small amount in order to prevent gut mucosa atrophy. Nutrition is an important aspect in critical care medicine, and enteral feeding should be attempted at least partially.
