AbstractSince imbalances in the immune system of the critically ill patient have been demonstrated, the role of the gastrointestinal tract for the pathogenesis of multiple organ failure has been a focus of research in intensive care medicine. Particularly, the integrity of the intestinal barrier function has been studied experimentally and clinically. The enormous number of gram-negative bacteria up to 10(11)/ml intestinal liquid inducing the release of significant amounts of endotoxin, is considered to be a vital threat to the intensive care unit (ICU) patient. Acute failure of the intestinal barrier following various types of severe shock or following parenteral nutrition inducing atrophy of intestinal mucosa may lead to multiple organ dysfunction. Maintenance of hemodynamic stability is a mainstay of therapy of the critically ill. In addition, the intestinal integrity can be preserved by the early onset of enteral nutrition. Moreover, recent concepts of enteral nutrition using immunomodulating nutrients like omega-3-fatty acids, glutamine, arginine, and nucleotides are under clinical evaluation.
