Perioperative nutrition support in critical illness

Abstract
The route, timing, and substrate composition of nutrition support can affect the course of critical illness. Early enteral nutrition is not only feasible and inexpensive, but also improves patient outcome by reducing septic morbidity. Continous perioperative enteral nutrition is feasible, safe, and beneficial. Reliable feeding access to the small intestine is a critical element for successful early enteral and perioperative nutrition. Parenteral nutrition should be reserved for those surgical patients who cannot be safely or adequately fed with enteral nutrition.
