Episode notes
TPN vs. PPN Basics
- TPN and PPN deliver micro and macronutrients.
- TPN requires central access, while PPN uses peripheral IV.
Choosing TPN or PPN
- For patients with central access and fluid concerns, prioritize TPN over PPN.
- PPN is suitable for short-term use (up to two weeks) or when central access is unavailable.
Indications for Parenteral Nutrition
- Short-term parenteral nutrition helps malnourished patients pre-surgery or during acute conditions like Crohn's flares.
- Long-term use is for patients with impaired GI absorption or motility.
