what does a NPN or DIN-HM let the consumer know
- that it has undergone & passed a review of its formulation, labelling, instructions for use
= safe product to choose
what in enteral nutrition
- involves giving nutrients thru the GI tract either orally or via tub feeding
what is parental nutrition
- involves giving nutrients intravenously
see figure 15-1 in the notes for a flow chart on selecting a feeding route
…
when might oral, nutrient fortified supplements be used
- if the individual is having difficulty maintaining adequate food intake
- but their GI tract is functional and are physically able to eat

what are some ways to improve a pt’s intake of oral supplements (7)
- let the pt sample diff products & determine what they enjoy
- serve supplements attractively
- keep it cold so it is refreshing for the pt
- if a pt finds the smell unappeling, cover the top w plastic wrap or a lid, leaving just enough room for a straw
- if have small appeitite, offer it in small amts & frequently
- provide easy access
- suggest alternatives
when is tube feeding used
- if an individual is unable to meet their nutrient needs orally
- but the GI tract is still functioning
list indications for tube feeding (7)
- swallowing disorders
- impaired upper GI motility

- uncontrollable vomiting or diarrhea
- severe malabsorption
what is a transnasal feeding
- one that is inserted through the nose
list 4 types of transnasal feedings
- nasogastric
- nasointestinal
- nasoduodenal
- nasojejunal
what is orogastric feeding
- tube inserted into the stomach through the mouth
who is orogastric feeding often used in? why?
- for infants bc a nasogastric tube may hinder the infant’s breathing
what is an enterostomy
- an opening into the GI tract thru the abdominal wall
what are 2 types of enterostostomy
- gastrostomy
- jejunostomy
what is a nasogastric tube
- tube place into the stomach via the nose
what is a nasointestinal tube
- tube place into the GI tract via the nose
- includes nasoduodenal & nasojejunal feeding routes
what is a nasoduodenal tube
- tube is placed into the duodenal via the nose
what is a nasojejunal tube
- tube is placed into the jejunum via the nose
what is a gastrostomy
- an opening into the stomach thru which a feeding tube can be passed
what is a PEG
percutaneous endoscopic gastrostomy
- a nonsurgical technique for creating a gastrostomy under local anathesia
what is a jejunostomy
- an opening into the jejenum thru which a feeding tube can be passed
what is a PEJ
percutaneous endoscopic jejunostomy
- nonsurgical technique for creating a jejunostomy
what is the duration of transnasal feeding tubes
- short term
- <4 weeks
what is an advantage of transnasal tubes (2)
- does not require surgery or incisions
- can be placed by a nurse
what are 2 disadvantages to transnasal feeding
- may cause nasal, throat, or esophageal irritation
- easy to remove by disorientated pts
what is the most common enteral route for pts with normal GI function
- nasogastric
what are 3 benefits to nasogastric tubes
- easy to insert & maintain
- feedings can be given intermittently without an infusion pump
- least expensive
what are 2 disadvantages to nasogastric feedings (2)
- risk of tube migration to the small intestine
- highest risk of aspiration in compromised pts
what are advantages to nasoduodenal & nasojejunal tubes (3)
- allows enteral feedings for pts who have obstruction, fistulas, gastric motility problems , or minimal stomach volume due to prior gastric surgery
- allow for earlier tube feedings than gastric placement
- lower risk of aspiration in compromised pts
what are 3 disadvantages of nasoduodenal and nasojejunal tube feedings
- more difficult to insert & maintain than nasogastric
- risk of tube migration to the stomach
- infusion pump required for formula administration
describe the duration of tube enterostomies
- long term access
- >4 weeks duration
what are the advantages to tube enterostomies (3)
- more comfortable than transnasal
- site is not visible under clothing
- allow the lower esophageal sphincter to remain closed = lowered risk of aspiration
what are the disadvantages to tube enterostomies
- must be placed by a physician or surgeon
- placement may require general anathesia
- risk of complications or infection from the insertion procedure
what is the most common mthod for long term tube feedings
- gastrostomy
what are the advantages of gastrostomy (2)
- easier insertion than jejunostomy
- feedings can be given intermittently without an infusion pump
what are the disadvantages of gastrostomy
- feedings are witheld 12-24 hrs before and 48-72 hrs after the procedure (for surgically placed tubes)
- moderate risk of aspiration in high-risk patients
what are the advantages to a jejunostomy (3)
- allows enteral feedings for pts who cannot undergo gastric feedings due to obstruction, gastric motility, minimal stomach volume
- earlier tube feedings then gastrostomy after placement
- lowest risk of aspiration
what are disadvantages to a jejunostomy
- most difficult insertion procedure
- infusion pump required for formula admin
- most costly
what are the 4 main types of enteral formulas available
- standard
- elemental
- specialized
- modular
what plays a role in formula selection (4)
- the pts medical condition
- digestive/absorptive capabilities
- nutrient status
- individual tolerance
what is another name for standard formula
- polymeric formula
who are standard formulas used for
- for people who can digest & absorb nutrients equally
what do standard formulas contain
- proteins from milk or soybeans
- carbs sources such as hydrolyzed corn starch and sugars
- contain whole proteins, complex carbohydrates, and long chain triglycerides = meaning the nutrients are intact and have not been broken down, which requires additional work by the digestive system
= must have full digestive & absorptive function
what are blenderized standard formulas produced from
whole foods such as
- chicken
- veggies
- fruits
- oils
- and added vitamins & minerals
who are elemental formulas used for
- for compromised digestive tracts
what do elemental formulas contain
- nutritionally complete
- but carbs & proteins which have been partially broken down to fragments which require little to no digestion
who are specialized formulas used for
- disease specific
ex. liver, kidney, & pulmonary failure, severe wounds
what are modular formulas
- created from individual marconutrient preparations
- can be combined to meet very specific needs
see figure 15-3 in the notes on selecting a formula
…
list 4 ways formulas differ in
- macronutrient composition
- energy density
- fibre content
- varying osmolality
who are high nutrient density formulas used for
- people w low fluid tolerance
- bc it offers the greatest quanitity of nutrition for least amt of fluid
list 5 factors that influence formula selection
- GI function
- nutrient & energy needs
- fluid reqiurements
- need for fibre modification
- individual tolerances (ex. allergies & sensitivities)
what kind of formula is used for people w functional GI tract? functional but impaired GI tract?
- functional = standard
- impaired = elemental
list 3 situations where individuals may have different nutrient & energy needs
- diabetes = need to control carbs
- critical care = high protein & energy requirements
- chronic kidney disease = limit intakes of proteins & several minerals
describe consideration when choosing a formula for someone with fluids restrictions
- formulas should ahve adequate nutrient & energy densities to provide the required nutrients in the volume prescribed
which individuals might beneficial from enteral formulas with fibre
can help manage problems like
- diarrhea
- constipation
- hyperglycemia
which individuals might need to avoid fibre (2)
if they have
- increased risk of bowel obstruction
- or other complications
