Delivery of enteral nutrition

There is increasing evidence that enteral feeding is superior to parenteral nutrition with regard to maintaining gut structure and function. Selection of the enteral access route depends on the type and anticipated duration of nutrient delivery. At present, enteral feeding devices can be divided into two major categories: those entering the gastrointestinal tract through the oral or nasal cavity (oroenteric or nasoenteric tubes) and those entering through the abdominal wall including gastrostomy, duodenostomy, or jejunostomy tubes. This article provides a review of methods to insert and confirm gastric and intestinal feeding tube placement. Care of the patient with an enteric tube will be described.
