The medical term for infusing a particular form of food through a vein (intravenously) is parenteral nutrition, often known as total parenteral nutrition. Parenteral nutrition is a method of delivering liquid nutrients such as carbs, proteins, lipids, vitamins, minerals, and electrolytes.
TPN is thinner than enteral solution. It may have a milkshake-like consistency. Total parenteral nutrition skips the digestive system entirely, allowing nutrients to be absorbed directly into the circulation. The solution is administered by a catheter inserted into a vein.
TPN, commonly known as intravenous or IV nutrition feeding, is a means of delivering nutrients to the body through the veins. In other words, it supplies nutrition to people who do not have a working gastrointestinal tract or who have illnesses that necessitate full bowel rest.
TPN is a nutritional combination that is injected directly into your vein. Your concoction will include whatever nutrition your body requires, as well as certain drugs. It is used to assist those who are unable to obtain sufficient nutrients from their diet alone. TPN is administered by a central venous catheter (CVC).
The most common use of TPN is in critically ill patients who are unable to feed themselves. It can also be used to make up for a lack of oral intake. TPN is only effective when patients are carefully chosen, the procedure is well-understood, and the risks are understood.
Parenteral feeding can be divided into two categories:
- Parenteral feeding in its entirety (TPN). TPN is given to your loved one if they have long-term nutritional demands.
- Parenteral feeding in the periphery (PPN).
The majority of clinicians understand that the initial weight gain associated with total parenteral nutrition (TPN) is due to fluid retention, whereas the fast weight loss that occurs shortly after TPN discontinuation is due to diuresis of same fluid (1).
Your healthcare professional inserts the catheter into the superior vena cava , a big vein that leads to your heart. A port, such as a needleless access port, may be placed by your healthcare professional to make intravenous feeding easier.
Liver disease is one of the leading causes of morbidity and mortality in patients receiving long-term total parenteral nutrition (TPN). Steatosis develops early on, progressing to steatohepatitis and, finally, cholestasis of various severity.
TPN is often contraindicated in the following circumstances, according to Maudar (2017):
- Infants having a short bowel length of less than 8 cm.
- Patients are irreversibly decerebrated.
- Patients who have severe cardiovascular or metabolic disorders.
- When it is possible to feed through the gastrointestinal tract.
Even if you are unable to eat, your bowels will continue to function, albeit less regularly than before. It’s possible that you’ll pass a stool (poo) that’s quite watery and contains some mucous.
A catheter is inserted into a vein, via which a specific nourishment solution is administered ( intravenous feeding). TPN can be used for a short period of time to help with surgical recovery or for a lengthy period of time in patients whose bowels are permanently unable to absorb nutrients.
TPN is injected into a vein via a PICC (peripherally inserted central catheter) line, although it can also be injected via a central line or a port-a-cath. TPN may be used for several weeks or months until the patient’s problems are resolved.
The following are some of the potential side effects of TPN:
- Electrolyte imbalances and dehydration.
- Thrombosis is a type of thrombosis that occurs when (blood clots).
- Hyperglycemia is a condition in which the blood sugar level rises (high blood sugars).
- Hypoglycemia is a state of low blood sugar (low blood sugars).
- Failure of the Liver.
- Deficits in micronutrients (vitamin and minerals).
The most frequent carbohydrate in PN solutions is dextrose. Dextrose solutions generally used for compounding range from 10% (for PPN solutions) to 70%, with final dextrose concentrations typically ranging from 5% (for PPN solutions) to 30%.
Deficiencies in nutrients. Patients who receive TPN for severe protein malnutrition (Kwashiokor) may develop hepatic steatosis as a result of decreased VLDL production.
TNA stands for total nutrient admixture, which is a parenteral nutrition (PN) formulation that contains all macronutrients in one bag, including dextrose, amino acids, and intravenous fat emulsions (IVFE) .
Although there is no evidence to support this practice [1,] guidelines recommend that when enteral nutrition tolerance is demonstrated, parenteral feeding should be tapered and discontinued when 60% of the patient’s demands are fulfilled enterally.

Parenteral nourishment is given to people of all ages. It can be administered to infants, children, and adults alike. Parenteral nourishment can keep people alive for as long as they need it.
Water (30 to 40 mL/kg/day), energy ( 30 to 35 kcal/kg/day , depending on energy expenditure; up to 45 kcal/kg/day for critically sick patients), amino acids (1. 0 To 2. 0 G/kg/day, depending on the degree of catabolism), essential fatty acids, vitamins, and minerals are all required for TPN. Basic Adult Daily Requirements can be found in the table below.
Depending on the etiology of intestinal failure, the long-term survival prospects of patients on complete parenteral feeding differ. TPN-dependent patients have a three-year survival rate of 65 to 80 percent.
TPN patients lost less weight at 1 week after surgery than controls, and this difference remained statistically significant up to 6 months after the nutritional treatment was stopped. Total body potassium and triceps skinfold showed a comparable, though not statistically significant, difference.
Your doctor will choose the appropriate calorie and TPN solution for you. You can sometimes eat and drink while receiving TPN nutrition. Your nurse will show you how to: Use the catheter to deliver the TPN formula and any other medications.
Depending on the pharmacy you visit, tPN Electrolytes intravenous solution (Lypholyte II/Nutrilyte II/TPN Electrolytes) costs roughly $185 for a 500 milliliter supply. Prices are only valid for cash paying consumers and do not apply to insurance programs.
Total parenteral nutrition (TPN), commonly known as parenteral nutrition (PN), is a type of intravenous nutrition delivered entirely through the bloodstream using an IV pump. Depending on the components and osmolality, tPN can be given by peripheral parenteral nutrition (PPN) or a central line.
The relative immaturity of the hepatic canalicular transporters mediating bile secretion is related to the increased frequency of TPN-associated cholestasis in premature newborns. The bile acid pool in premature neonates is reduced, and hepatic mitochondrial activity is compromised.
During complete parenteral feeding, bilirubin metabolism disturbances such as jaundice and pigment gallstone development might occur (TPN).
What are the signs and symptoms of cholestasis caused by TPN? In neonates with TPN-associated cholestasis, liver failure and cirrhosis can develop quickly. Jaundice (yellowing of the skin and eyes), difficulty feeding, failure to thrive, irritability, weariness, itching, and other concerning symptoms are all possible.
The median survival after starting complete parenteral feeding was 5 months (range, 1–154 months) in the 52-patient group. The date of TPN cessation was nearly always the same as the date of death for nearly all other patients, and death was the most prevalent reason for TPN withdrawal (Table 4).
“A lot relies on your underlying health. Many people who have malabsorption owing to short bowels or a transient obstruction can be weaned off TPN, he says. For most people, three to twelve months of therapy is required, with the amount of TPN required gradually decreasing over time.Category:Nutrition
