Total parenteral nutrition (TPN) is a form of nutritional therapy that delivers essential nourishment and fluids directly into the bloodstream through intravenous (IV) administration. This method is employed for individuals incapable of consuming food or liquids orally. TPN is commonly prescribed for patients experiencing severe illness or significant weight loss. Various factors are considered to determine the appropriate regimen of total parenteral nutrition, including the individual’s age, height, weight, stress level, and protein and lipid requirements.
