The early institution of enteral nutrition is now accepted as the preferred
route of feeding in critically ill patients with a functioning
gastrointestinal tract. It is particularly important to establish early
enteral nutrition in mechanically ventilated patients because of the metabolic
demands associated with mechanical ventilation. The options for enteral access
in mechanically ventilated patients are reviewed, with an emphasis on those
techniques that may be performed at the bedside. The advantages,
disadvantages, and complications of the different techniques will be
considered.
