Abstract    Surgical critically ill patients are hypermetabolic, accompanying with the system inflammation response and increased nutrient requirement. Nutrition support is now considered as an important part of therapy for critically ill patients. Rational nutrition support implement should be based on the overall consideration of organ function and enteral nutrition tolerability in surgical critically ill patients, including the appropriate substrate, timing, route and monitoring. Clinical studies also demonstrate that some new formulae enriched with specific nutrients may improve the organ and immune function, decrease the incidence of morbidity and mortality, and shorten the hospital stay in critically ill patients.
