title: Basic principles of intravenous nutritional support.
abstract: Parenteral nutrition has been one of the major advances in clinical medicine in the 20th century. By maintaining or re-establishing optimal nutritional status, one can help to ensure an optimal response to appropriate medical or surgical management of the primary disease process. In order to plan an appropriate nutritional regimen, the health-care provider must be equipped to pursue the following thought processes: Understand the consequences of malnutrition. Identify the patient who may benefit from nutritional support. Assess the underlying clinical and metabolic setting. Assess the current nutritional status. Formulate a goal of nutritional intervention--a therapeutic plan. Determine the route and method of administration; the quantity and source of energy and nitrogen; and requirements for fluid, electrolytes, minerals, vitamins, and trace elements. Monitor the patient. Evaluate the efficacy and determine the duration of therapy.
