hyperalimentation
Complete intravenous nutrition providing all calories, proteins, fats, vitamins and minerals through a central venous catheter.
Full Definition
Hyperalimentation refers to the complete provision of nutrition through intravenous means, typically used when enteral feeding is contraindicated or impossible in critically ill neonates. This method delivers all essential nutrients including amino acids, glucose, lipids, electrolytes, vitamins and trace elements directly into the bloodstream via central venous access. In NICU settings, hyperalimentation is crucial for supporting growth and development in premature infants or those with gastrointestinal conditions that prevent normal feeding. The composition must be carefully calculated and monitored to prevent complications such as hyperglycemia, electrolyte imbalances, or catheter-related infections.
Usage
Usage note: Often used interchangeably with TPN in clinical documentation, though technically hyperalimentation emphasizes high-calorie provision.
