According to the National Institutes of Health, total parenteral nutrition (TPN) is the complete intravenous feeding of a patient, bypassing the digestive system. To achieve this, TPN must be delivered directly into the bloodstream via specific vascular access points. Understanding what are the routes of administration of TPN is crucial for patient care, safety, and determining the appropriate method based on a patient's nutritional needs and treatment duration.

According to the American Society for Parenteral and Enteral Nutrition (ASPEN), venous access for parenteral feeding is a vital decision in patient care. The choice of which vein is used for parenteral feeding depends on several factors, including the type of nutritional solution, the expected duration of treatment, and the patient's medical condition.

Due to its high osmolarity, Total Parenteral Nutrition (TPN) is administered exclusively through central venous access, making it impossible to deliver through a standard peripheral IV line. This critical distinction prevents serious vein damage and irritation that would occur otherwise, ensuring patient safety during nutritional therapy.

Due to its high concentration, or osmolarity, the standard formulation for total parenteral nutrition (TPN) *must* be delivered through a central venous catheter, not a peripheral line. This crucial distinction is based on the solution's properties and the body's vascular system, ensuring safe and effective delivery of complete intravenous nutrition.
