Difference Between TPN and PPN

TPN vs PPN

Total Parenteral Nutrition (TPN) and Peripheral Parenteral Nutrition (PPN) are provided to patients who do not have any other source of nutrition. Both the TPN and the PPN are provided by IV. Though the two are used to provide the required nutrition to a patient, they are different in many aspects.

Total Parenteral Nutrition means total nutrition, which is provided when a patient does not receive any other form of nutrition. When a patient is on Total Parenteral Nutrition, he relies on it completely. On the other hand, Peripheral Parenteral Nutrition, or PPN, is only partial. This means that the patient may be getting nutrition from other sources along with the PPN.

Another difference that can be seen is that Total Parenteral Nutrition comes in a higher concentration, and can only be administered through a larger vein. On the contrary, Peripheral Parenteral Nutrition comes in a lesser concentration, and can be delivered through a peripheral vein. Generally, the TPN is administered in the larger vein in the chest or neck.

Well, the TPN is caustic when compared to PPN. The TPN is caustic as it contains glucose and minerals, as well as electrolytes.

PPN is not a preferred nutritional supplement for a long time. This is because it is not safe to use hyperosmolar solutions in peripheral veins for a very long time. However, the TPN can be used for a very long time as it is delivered through a central vein.

Total Parenteral Nutrition is given to persons who are suffering from digestive disorders, or who are having any extended consequences of surgery or accident. The Peripheral Parenteral Nutrition is provided if a person’s digestive system has been blocked, or if the patient is not getting enough nutrition during an extended stay in the hospital.

Though both the TPN and the PPN have almost similar components, the TPN has a higher concentration of the components.

Summary

1. 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.

2. TPN comes in a higher concentration, and can be administered through larger veins. PPN comes in a lesser concentration, and can be delivered using a peripheral vein.

3. When compared to TPN, the PPN is not a preferred nutritional supplement for a long time.

4. TPN comes in a higher concentration of components when compared to PPN.
