Total Parenteral Nutrition (TPN)
First Things First (assess & treat for the following)
- Is TPN appropriate?
- Indications:
- Enteral nutrition always preferred
- Nonfunctioning GI tract (malabsorption, massive small bowel resection, intractable nausea/vomiting/diarrhea, intestinal obstruction)
- Moderate/severe stress
- Severely malnourished
- Contraindications
- Functioning GI tract
- Functioning GI tract anticipated in 5-7 days
- Inability to gain venous access
- Risks outweigh benefits (see Complications section)
- Terminal illness/comfort measures only
- Indications:
- Which is better, central or peripheral parenteral nutrition?
- Central parenteral nutrition: line tip in SVC
- May be placed percutaneously via subclavian (preferred), internal jugular or femoral veins . A peripheral vein may be used to insert a long catheter (PICC, “long arm Groshong”).
- May be placed surgically (Hickman, Port-a-cath, Groshong)
- Peripheral parenteral nutrition: administered through a peripheral vein
- Infused solution must be dilute (< 900 mOsm).
- Difficult to meet nutritional needs if fluid restriction required
- Short-term use only (< 10-14 days) because of increased risk of thrombophlebitis
- Not intended for severely malnourished pts
- Central parenteral nutrition: line tip in SVC
