Document Summary

Decisions related to pn are based on nutrition care process: length of time the patient will require nutritional support, current medical condition and diagnosis. Components are in elemental or pre-digested form: protein as amino acids, cho as dextrose, fat as lipid emulsion, electrolytes, vitamins and minerals. Unlike enteral nutrition formulas, which are typically purchased in a form appropriate for patient administration, pn formulas are mixed or compounded in the hospital pharmacy. Can be two-in-one system: dextrose and amino acids hung separately from lipids, lipids added separately based on container size (100 ml, 250 ml, or 500 ml: allows for greater flexibility in the amounts of dextrose and amino acids that can be given, also clear, can allow for identification of substrates. Protein is in the form of amino acids: lower concentrations (3. 5% or 35mg/l) are used for peripheral administration, higher concentrations (8. 5%, 10%, 11%, 15% and 20%) are used in central administration.
