Feedback:
Total parenteral nutrition (TPN) is a specifically formulated and calculated solution that is nutritionally complete to meet a specific individual's needs and provides more calories than PPN. Peripheral parenteral nutrition (PPN) contains lesser concentrations of the same ingredients found in central vein TPN, administered into a peripheral vein. It is used to provide temporary nutritional support and to promote protein synthesis and weight gain when oral intake is inadequate or contraindicated.
