nasoenteric
orogastric
What route of enteral nutrition is used for long term?
enterostomy; mostly percutaneous endoscopic gastrostomy
What are problems with intermittent feeding?
larger fluid/ osmotic burdens over shorter periods of time –> diarrhea, less tolerated
What is a meal replacement?
semi-palatable partially digested proteins given as a supplement or full nutrient replacement in those ABLE to swallow
What products are used for meal replacement?
- Ensure
- Osmolite
- Isosource
- Boost
What is elemental/ peptide replacement?
non-palatable predigested protein given via tube feeding
What patients receive elemental/ peptide replacement?
- malabsorptive issues (IBD,IBS)
- transition from TPN to enteral

Vivonex
Peptamen
Vital
