Critical care nutrition: routes of feeding
1Department of Clinical Studies, School of Veterinary Medicine, University of Pennsylvania, Philadelphia 19014-6010, USA.
Abstract:
Nutrition is an integral part of the management of the critically ill patient. Nutritional support can be provided by either parenteral or enteral routes. Whenever possible, enteral nutrition is the method of choice, as it reduces complication rates and improves outcome. Potential choices for enteral feeding include nasoesophageal, esophagostomy, gastrostomy, jejunostomy, and transpyloric feeding tubes. The modes of parenteral and enteral nutrition are reviewed individually, including indications and selection of appropriate routes of feeding, methods of tube placement, and benefits and risks associated with each feeding approach.

Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
