What is the difference between enteral nutrition versus parenteral nutrition?

Enteral nutrition is administered through a feeding tube placed into the stomach or intestines. Parenteral nutrition is administered through a traditional intravenous (IV) line or via a central IV surgically placed during an outpatient procedure.

Why is enteral a better choice over 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.

What is the difference between parenteral feeding and TPN?

Enteral solution is thicker than TPN. It may have the consistency of a milkshake. Total parenteral nutrition bypasses the digestive system entirely and goes directly into the bloodstream, where the nutrients are absorbed. The solution is given through a catheter that has been placed in a vein.

Why is tube feeding better than TPN?

Tube feeding or enteral nutrition is a method of supplying nutrients directly into the stomach via a tube. It is a simpler and cheaper method than TPN. Moreover, it shows fewer complications and infections than TPN. The nutrients go through the GI tract in the same way when we ingest foods.

What are advantages of enteral feeding?

The theoretical advantages of enteral nutrition In summary, enteral nutrition improves GI blood flow and improves GI mucosal health. It maintains villous height by causing the release of trophic agents e.g.. cholecystokinin, bombesin, bile salts, etc – which cause the GI mucosal cells to proliferate.

What are the advantages of enteral nutrition?


  • cheaper.
  • simpler.
  • fewer complications.
  • for efficient use of nutrients.
  • stimulates intestinal blood flow.
  • maintain GI mucosal barrier (prevents bacterial translocation and portal endotoxemia)
  • reduced gut associated lymphoid system (GALT) -> becomes a source of activated cells and proinflammatory stimulants.

Is a PEG tube enteral or parenteral?

Percutaneous endoscopic gastrostomy (PEG) tubes serve as the favorable route of feeding and nutritional support in patients with a functional gastrointestinal (GI) system who require long-term enteral nutrition, usually beyond 4 weeks.

Why is TPN given via central line?

Historically, total parenteral nutrition (TPN) has been administered by the central venous route because of the rapid development of thrombophlebitis when TPN solutions are administered into peripheral veins.

Which is a disadvantage to enteral feeding?

There are disadvantages with enteral feedings. If the child has gastroesophageal reflux, aggressive enteral feeding may increase his risk of aspiration or vomiting. Other physical disadvantages are diarrhea, skin breakdown or anatomic disruption. Mechanical disadvantages include a dislodged or occluded feeding tube.

What are the disadvantages of parenteral feeding?

Complications Associated with Total Parenteral Nutrition Dehydration and electrolyte Imbalances. Thrombosis (blood clots) Hyperglycemia (high blood sugars) Hypoglycemia (low blood sugars)

What are the advantages of parenteral feeding?

The major advantage of parenteral nutri tion is the provision of adequate nutrients in the face gastrointestinal dysfuncion. It is also useful in the face of fluid restric tion since caloric density can be in creased with a central venous catheter beyond that tolerated by the enteral route.

Is PEG feed enteral?

A percutaneous endoscopic gastrostomy (PEG) is a procedure to place a feeding tube. These feeding tubes are often called PEG tubes or G tubes. The tube allows you to receive nutrition directly through your stomach. This type of feeding is also known as enteral feeding or enteral nutrition.

Can you put TPN through a peripheral line?

Total parenteral nutrition (TPN) is given through a vascular access device such as a Peripheral Intravenous line, Midline or most preferably a Central Line.

What is enteral and parenteral nutrition?

What do Enteral and Parenteral Nutrition Refer To? Enteral nutrition refers to any method of feeding that uses the gastrointestinal (GI) tract to deliver nutrition and calories. It can include a normal oral diet, the use of liquid supplements or delivery by use of a tube (tube feeding).

What is the difference between total and peripheral parenteral nutrition?

Total parenteral nutrition (TPN) is prescribed to people with damaged or poorly functioning digestive systems. Before your loved one can receive TPN, a surgeon places a vascular access device, like a peripherally inserted central catheter (PICC), into their superior vena cava. Peripheral parenteral nutrition (PPN) is less invasive.

Is enteral or gastrointestinal nutrition right for You?

While enteral nutrition is always preferred when technically possible, some people may have a variety of medical issues that make the safe use of the GI tract difficult. Alternatively, their calorie and nutrient needs may not be met by the current level of functioning of their GI tract.
