What does PPN stand for?

PPN stands for Peripheral Parenteral Nutrition. This method of nutrition delivery is used for patients who cannot take adequate nutrition orally or enterally and require a form of intravenous feeding. PPN involves administering nutrients directly into a peripheral vein, which is typically in the arms.

The choice of the term "peripheral" indicates the use of smaller veins, as opposed to central parenteral nutrition, which is administered through larger central veins. PPN is particularly useful for short-term nutritional support, ensuring that patients receive essential nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals, without compromising the functionality of the gastrointestinal tract.

Understanding PPN helps in recognizing that it is specifically designed for particular clinical situations, especially when large volumes of solution are not required, making it distinct from other types of parenteral nutrition, which may use central venous access.
