hyperalimentation
Intravenous nutritional support providing complete nutrition through central venous access.
Full Definition
Total parenteral nutrition delivered through a central venous catheter to provide complete nutritional support when the gastrointestinal tract cannot be used. In pediatric gastroenterology, hyperalimentation is commonly used in patients with short bowel syndrome, severe inflammatory bowel disease, or following major gastrointestinal surgery. The solution contains amino acids, dextrose, lipids, vitamins, minerals, and trace elements tailored to the patient's specific needs. Long-term complications include central line infections, metabolic disturbances, and hepatic dysfunction. The goal is always to transition to enteral nutrition when possible.
Usage
Usage note: Older term still commonly used; TPN is more current terminology.
