Energy Supply via Intravenous Macronutrient Delivery (TPN/PPN)
- Target
- TPN/PPN
- Molecular classification
- Nutrient Delivery System, Medical Procedure
01
Overview
Energy supply via intravenous macronutrient delivery is a method of providing essential nutrients (carbohydrates, proteins, and fats) directly into the bloodstream, bypassing the gastrointestinal tract. It is used in patients who cannot use their digestive system due to various medical conditions. TPN and PPN are the main methods of administration. It requires close monitoring to prevent complications such as infections and metabolic imbalances.

Mechanism of action
Direct delivery of carbohydrates, proteins, and fats into the bloodstream, bypassing the gastrointestinal tract to provide energy, amino acids, and essential fatty acids for metabolic needs, tissue maintenance, and repair.
