ReviewEarly nutrition support in critical care: a European perspective.
Today, early nutrition support is considered standard care in most ICUs. The recommended method is the enteral route, although there is only minor evidence for this. Often inadequate delivery of energy and a cumulative energy deficit are implied. The purpose of this paper is to evaluate the indication for early enteral nutrition or immunonutrition and to discuss the application of additional parenteral nutrition. ⋯ Early enteral nutrition is recommended for critically ill patients, with special formulas indicated in specific subgroups of patients. If enteral nutrition is insufficient or fails, parenteral nutrition should be instituted, respecting the often reduced demand for exogenous substrates in critically ill patients.

Intradialytic nutritional support has been used for more than 30 years both in critically ill patients with acute renal failure and during maintenance hemodialysis. Present knowledge allows better estimation of its metabolic and nutritional efficacy, as well its effect on patient outcome. ⋯ Current information helps to better assess the effects of intradialytic nutritional support, to clarify the nutritional management of renal failure patients and to provide recommendations. Future research should focus on the possible means to improve the efficacy of nutritional support, either by modifying its components of by associating anabolic or anticatabolic agents.
