,should be 1st consideration
parenteral nutrition - ✔✔provision of nutrients intravenously (last resort)
insufficient GI tract function or no access
TPN
- hyperglycemia
- gut atrophy
- stress on the liver
- 7 days
benefits of enteral vs parenteral nutrition - ✔✔better GI barrier function
preserved GI immunity
attenuate catabolic response
better blood glucose control

,decreased rates of infection
#1 most common TPN complication - ✔✔hyperglycemia
what conditions often require enteral nutrition? - ✔✔impaired nutrient ingestion
(dysphagia, neurologic disorders, facial trauma, oral or esophageal trauma, congenital
abnormalities, respiratory failure, cystic fibrosis, dementia, failure to thrive, burns,
cancer)
impaired digestion, absorption, metabolism (severe gastroparesis)
enteral nutrition access depends on... - ✔✔anticipated length of time of enteral feeding
(temp NGT / OGT vs PEG)
risk for aspiration or tube displacement
clinical status
presence / absence of normal digestion and absorption

, planned surgical intervention (post pyloric sometimes anchored by IR / GI so doesn't
migrate)
enteral nasogastric route - ✔✔short term: up to 3 or 4 weeks
normal GI function
bolus, intermittent, or continuous infusions
can still take PO if appropriate
enteral nasoduodenal / nasojejunal route - ✔✔short term: up to 3 or 4 weeks
gastric motility disorders, esophageal reflux, persistent nausea and vomiting
aspiration risk, gastroparesis, hyperemesis gravidarum
