Indications for TPN

 used to meet nutritional needs for pts who can't ingest, absorb, or digest essential
nutrients via the GI tract


TPN Nutrient Components

water, glucose concentration (10% for adults, 15-25% depending on condition of pt)


Infusion Considerations

administered via a "dedicated port" of a central line; TPN is "custom" mix and
reconstituted in pharmacy under strict, aseptic technique


Infusion Guidelines

changed every 24 hours; TPN is administered with in line micron filter (special IV
tubing), no meds are added to TPN solution bags; infused as a closed system and no
piggy backing; kept refrigerated until 30 min prior to being infused


If TPN infusion unavailable


 IV solution of Dextrose 10% and water (D10W) until TPN available, to prevent
rebound hypoglycemia
