Difference Between TPN and Tube Feeding

The key difference between TPN and tube feeding is that total parenteral nutrition or TPN refers to the supply of all daily nutrition directly into the bloodstream, while tube feeding refers to the supply of nutrition through a tube that goes directly to the stomach or small intestine.

Is TPN the same as tube feeding?

The feeding tube is given directly into part of the digestive system. It can be through a gastrostomy tube (g-tube) in the stomach or a jejunostomy tube (j-tube) in the small intestine. Enteral solution is thicker than TPN. ... The solution is given through a catheter that has been placed in a vein.

What is the difference between TPN and parenteral nutrition?

Total parenteral nutrition (TPN) is the only source of nutrition the patient is receiving. ... Despite a high risk of infection, TPN is meant for long-term use. Peripheral parenteral nutrition (PPN) is meant to act as a supplement and is used when the patient has another source of nutrition.

Is TPN enteral or parenteral?

Parenteral nutrition, also called total parenteral nutrition (TPN) or hyperalimentation, involves the intravenous delivery of a full complement of nutrients—glucose, amino acids, lipids, vitamins, and minerals. This method is used when the GI tract fails to work properly.

Why is enteral feeding preferred 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.

Do you poop when on TPN?

Although you may not be able to eat, your bowels will continue to work but usually not as frequently as before. You may find that you will pass a stool (poo) which is quite liquid and has some mucus in it.

Why is TPN given at night?

Since the central venous catheter needs to remain in place to prevent further complications, TPN must be administered in a clean and sterile environment. ... Most TPN patients administer the TPN infusion on a pump during the night for 12-14 hours so that they are free of administering pumps during the day.

How long can you stay on TPN?

The long-term survival prospects of patients maintained through total parenteral nutrition vary, depending on the cause of intestinal failure. Three-year survival of TPN-dependent patients ranges from 65 to 80 percent.

What are the side effects of TPN?

Possible complications associated with TPN include:

• Dehydration and electrolyte Imbalances.
• Thrombosis (blood clots)
• Hyperglycemia (high blood sugars)
• Hypoglycemia (low blood sugars)
• Infection.
• Liver Failure.
• Micronutrient deficiencies (vitamin and minerals)

Who is TPN given and why?

TPN is ordered for patients who, for whatever reason, cannot obtain adequate nutrition through their digestive tract. This could be because of a blockage or a leak in the digestive tract. Some patients have absorption issues as well, perhaps due to short bowel syndrome.

What is the most common complication of TPN?

TPN requires a chronic IV access for the solution to run through, and the most common complication is infection of this catheter. Infection is a common cause of death in these patients, with a mortality rate of approximately 15% per infection, and death usually results from septic shock.

Why is Jejunostomy done?

A jejunostomy may be formed following bowel resection in cases where there is a need to bypass the distal small bowel and/or colon due to a bowel leak or perforation. ... Depending on the length of jejunum resected or bypassed the patient may have resultant short bowel syndrome and require parenteral nutrition.

Which is the most serious complication of enteral tube feeding?

Pulmonary aspiration is an extremely serious complication of enteral feeding and can be life-threatening in malnourished patients. The incidence of clinically significant aspiration pneumonia is 1% to 4%. Symptoms of aspiriation include dyspnea, tachypnea, wheezing, rales, tachycardia, agitation, and cyanosis.
