TPN (Total Parenteral Nutrition)
Questions and Answers 2024/2025
TPN aka
Hyperalimentation
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
amino acids, glucose, fat emulsion, vitamins, electrolytes, minerals, trace elements,
water, glucose concentration (10% for adults, 15-25% depending on condition of pt)
Infusion Considerations
if glucose concentration > 10%, administered via central or PICC line; TPN infusions
administered via a "dedicated port" of a central line; TPN is "custom" mix and
reconstituted in pharmacy under strict, aseptic technique
Infusion Guidelines
Administered via an infusion pump usually over 24 hours; TPN, lipids, and tubing
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
Lipids
