What is another name for total parenteral nutrition (TPN)?

Total parenteral nutrition (TPN) is also known as hyperalimentation. This term reflects the comprehensive nature of the nutritional support provided through TPN, which delivers all necessary nutrients directly into the bloodstream via an intravenous line. Hyperalimentation specifically indicates the administration of nutrients in amounts greater than what might be provided through regular dietary intake, ensuring that patients receive adequate calories, protein, carbohydrates, fats, vitamins, and minerals when they are unable to eat normally.

Other options, while related to nutritional support, do not correctly describe TPN. Enteral feeding refers to nutritional support delivered directly into the gastrointestinal tract, which is fundamentally different from parenteral nutrition. Liquid diet therapy generally involves consuming liquid foods or supplements but does not refer to parenteral nutrition at all. Intravenous hydration typically involves the administration of fluids and electrolytes, which may not include the full spectrum of nutrients provided by TPN. Therefore, the term hyperalimentation most accurately captures the essence of total parenteral nutrition.
