Provision of unusually large amounts of energy, either intravenously (parenteral nutrition) or by nasogastric or gastrostomy tube (enteral nutrition).
Infusion of life-sustaining fluids, electrolytes, and elements of nutrition intravenously or via the gastrointestinal tract.
The feeding of large amounts of nutrients by mouth or intravenously to someone with serious nutritional deficiency.
Early term for parenteral nutrition; nutrition support provided when a hypertonic solution of nutrients is infused via the subclavian or umbilical vein.
Enteral or parenteral infusion of a solution containing complete nutritional requirements for normal growth, development, and tissue repair.
The enteral and parenteral infusion of a solution that contains sufficient amino acids, glucose, fatty acids, electrolytes, vitamins, and minerals to sustain life, maintain normal growth and development, and provide for needed tissue repair. The gastrointestinal tract is the route of choice if it is functional. Intravenous hyperalimentation must utilize less concentrated formulations because of the potential for chemical phlebitis that may result from osmotic stress. Infusion through a central line catheter into the superior vena cava provides a sufficient blood volume to dilute more hypertonic solutions. One crucial drawback of a central line is the potential for the line to become infected with either bacteria or fungi.
The process of providing higher-than-normal quantities of nutrients, often delivered intravenously or through a stomach tube, is known as hyperalimentation.
