Parenteral feeding refers to liquid nutrition processed by the veins. It’s considered riskier than enteral feeding, but often results in improved health and energy. Some people undergo parenteral feeding while recovering from surgery or other medical procedures, while others require it long-term.
It can include a normal oral diet, the use of liquid supplements or delivery by use of a tube (tube feeding). The site of entry of the tube and tube types will be discussed under "enteral access." Parenteral nutrition refers to the delivery of calories and nutrients into a vein.
Parenteral nutrition means feeding intravenously (through a vein). "Parenteral" means "outside of the digestive tract." Whereas enteral nutrition is delivered through a tube to your stomach or the small intestine, parenteral nutrition bypasses your entire digestive system, from mouth to anus.
Enteral feeding is aimed at helping people who still have functional digestive systems but may not be able to feed themselves due to being in a coma or suffering a stroke, while parenteral feeding is for those whose digestive systems are not functioning.
Enteral nutrition is the administration of nutrients via the gastrointestinal tract, whereas parenteral nutrition is the administration of nutrients via alternative routes, such as intravenously via a catheter.
Enteral Nutrition vs Parenteral Nutrition: controversial issue; at present best recommendations are to optimize oral/enteral nutrition, avoid forced starvation if at all possible, and judiciously use supplemental parenteral nutrition.
In general, enteral nutrition is preferred to parenteral nutrition as it is more physiological, simpler, cheaper and less complicated. However even nasogastric feeding needs care and the more complex types of enteral nutrition such as gastrostomy and jejunostomy need significant interventions.
Enteral nutrition, specifically tube feeding, is the preferred method of feeding because it is cheaper, has fewer complications, and has better outcomes than does parenteral nutrition.
Parenteral nutrition is more likely to cause hyperglycemia and increased sepsis than enteral nutrition. Strict glucose control has been shown to reduce the incidence of sepsis and...
Pros. Utilizes the natural digestive process, aiding in the maintenance of gastrointestinal function. Helps maintain the integrity of the gut barrier, preventing complications associated with prolonged lack of oral intake. Allows for a sense of normalcy, as individuals can continue to experience the act of eating and swallowing. Considerations.
