One 20 mL volume of TPN Electrolytes (multiple electrolyte additive) is added to each liter of amino acid/dextrose solution. Alternatively, the TPN Electrolytes can be added to the bottle of amino acids or concentrated dextrose, to permit addition of the necessary phosphate additive to the remaining bottle. This latter technique helps avoid physical incompatibilities between calcium and phosphorus. A potassium phosphate additive is recommended for addition to nutritional solutions containing TPN Electrolytes. Between 10 and 30 mEq of potassium (as phosphate) should be added per liter of TPN solution, to augment the 20 mEq of potassium provided by TPN Electrolytes.
Between two and three liters of TPN solution with added TPN Electrolytes are usually administered daily to adults. Solutions are given continuously over the entire 24-hour period at a constant rate, ranging from 83 to 125 mL/hour. TPN solutions containing TPN Electrolytes and concentrated dextrose are administered intravenously, through a central venous catheter.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
