Meeting exceptional nutritional needs. 2. Elemental enteral alimentation.

Elemental enteral alimentation (EEA) is an alternative to parenteral nutrition in patients with a functioning gastrointestinal tract and increased caloric requirements or in whom regular oral feeding is impossible or impractical. EEA is given by nasogastric, jejunostomy, or gastrostomy tube. It is useful in cases of short-gut syndrome, pancreatic disease, partial intestinal obstruction, colitis, neuropsychiatric cachexia, trauma, fistula, vascular insult, and renal and liver disease, as well as in patients being prepared for surgery or requiring hyperalimentation after surgery or abdominal irradiation. Strict attention must be paid to fluid and electrolyte status and to blood and urine glucose levels in patients receiving EEA. With use of a nasogastric tube, infection of the middle ear is a possible but uncommon complication.
