TPN is a mixture of separate components which contain lipid emulsions, dextrose, amino acids, vitamins, electrolytes, minerals, and trace elements. [7][8] TPN composition should be adjusted to fulfill individual patients' needs. The main three macronutrients are lipids emulsions, proteins, and dextrose.

What are components of parenteral nutrition?
Parenteral nutrition (PN) is the intravenous administration of nutrients necessary for the maintenance of life. The nutrient components of PN include dextrose, amino acids, fat, electrolytes, multivitamins, and trace elements.
What does a total parenteral nutrition TPN contain?
The total parenteral nutrition (TPN) solution will provide your child with all or must of his or her calories and nutrients. The solution contains protein, carbohydrates (in the form of glucose), glucose, fat, vitamins, and minerals. Protein is important for building muscle strength.
What is the main difference between PPN and TPN?
The difference between TPN and PPN is that TPN is a long-term therapy by which patients are receiving nutrition despite having a high risk of infection. On the other hand, PPN is a supplement that is used when the patient has other sources of nutrition.
What is acetate TPN?
Because metabolism of the TPN formula generates an acid load that can induce hypercalciuria, we evaluated the effect of supplementing the formula with acetate. ... Acetate, which is metabolized to bicarbonate, increased blood pH and decreased renal acid excretion.
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.
Is TPN given through a PICC line?
TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath.
What electrolytes are in TPN?
(sodium chloride, calcium chloride, potassium chloride, magnesium chloride, and sodium acetate anhydrous)
Why is it called total parenteral nutrition?
Parenteral nutrition, often called total parenteral nutrition, is the medical term for infusing a specialized form of food through a vein (intravenously). The goal of the treatment is to correct or prevent malnutrition.
What is the difference between TPN and PN?
Total Parenteral Nutrition is total nutrition, which is provided when a patient does not receive any other form of nutrition. Peripheral Parenteral Nutrition is only partial, which means that the patient may be getting nutrition from other sources.
Is TPN the same as PN?
Compared to TPN, PPN is low in carbohydrates (less than 10%) and offers a lower concentration of nutrients. As a result, more volume is needed to reach the same nutritional value as TPN. PPN offers a lower risk of infection than TPN, though both forms are still more expensive than enteral nutrition options.
What electrolyte imbalance can TPN cause?
The most common electrolyte abnormalities during TPN were hypophosphatemia (24 cases, 30%), and hypomagnesaemia (22 cases; 27.5%) with no differences by gender. Hypokalaemia also occurred in 22 patients (27.5%) and was more common in women by 29.6% (p < 0.05).
What is the pH of TPN?
pH values in complete TPN admixtures were in range 5.6 -6.7. Comparing with t=0, these values did not change (±0.05 of units) during storage (Fig.
What is severe metabolic acidosis?
Definition. Metabolic acidosis is a condition in which there is too much acid in the body fluids.
Is TPN hard on the kidneys?
We describe a profound decrease in renal function associated with long-term TPN, most of which is largely unexplained.
Why does TPN damage the liver?
Nutrient Deficiencies. Patients who begin TPN because of severe protein malnutrition (Kwashiokor) may develop hepatic steatosis because of decreased very low density lipoprotein synthesis.
