What is parenteral nutrition reserved for?
Proposed Benefits of Enteral vs. Parenteral Nutrition? (3) |
nonfunctional or severely diminished small bowel
- better GI barrier fx - preserved GI immunity (perserve gut-associated lymphoid tissue (GALT) actv) - decreased rates of infection (presumably unrelated to GI tract) |
|
|
Impaired nutrient ingestion; inability to consume adequate nutrition orally; impaired digestion, absorption, metabolism; severe wasting or depressed growth.
These conditions often require what? |
enteral nutrition.
|
|
|
Gastrointestinal incompetence, or critical illness w/ poor enteral tolerance or accessibility often requires what?
|
parenteral nutrition
|
|
|
Which enteral routes are preferred for short term (3-4wks)?
- which is for bolus, intermittent, or continuous infusions? - gastric motility disorders, esophageal reflux, or persistent N&V? |
Nasogastric, nasoduodenal, jasojejunal.
- nasogastric - the other two. |
|
|
What non-surgical technique is preferred for enteral access >4wks?
Surgical? |
percutaneous endoscopic gastrostomy or jejunostomy.
surgical gastrostomies and jejunostomies. |
|
|
When would you use a high-N formula for enteral feeding?
Is lactose used in the CHO's that make up 30-to-90% of the kcal in these formulas? |
Increased protein requirements: burns, fistulas, sepsis, trauma
no. |
|
|
Between CPN and PPN parenteral nutrition sites, which is only for short term and cannot tolerate concentrated solutions?
Principal complication PPN? |
PPN.

|
|
What is the difference b/t compounding methods 1 and 2?
|
1: lipids admin'ed separately so they don't precipitiate - mix them *right* before you admin
2: Total nutrient admixture or 3-in-1 solution of lipid, amino acids, glucose |
|
|
What should be avoided with continuous nutrient infusion?
Cyclic infusion is given during what time of day? |
Avoid abrupt cessation and rebound hypoglycemia
At night (8-12hrs a day) |
|
|
What is refeeding syndrome?
- how do you avoid this? |
pt who hasn't been getting nutrients for some reason gets put on some forced feeding --> ^Insulin --> P, K, Mg go into the cell --> hypoP, hypoK, hypoMg.
limit CHO admin if they've been in starvation mode for awhile, while giving intracellular electrolytes. |
