One of the problems with patients hospitalized in the intensive care unit is ileus, which sets a limit for early enteral nutrition. The risk of aspiration and the following pneumonia is another concern for early enteral nutrition. It has been shown that despite the absence of bowel sounds in critically ill patients, the bowel has the ability to absorb nutrients and
there is no prohibition to delay enteral nutrition (7). Although the benefits of early enteral nutrition is known at the cellular and tissue level, its effect on mortality and morbidity is still unknown. Some studies have shown an improvement in one or a number of the outcomes (8-11).
