Enteral vs Parenteral Nutrition Flashcards
What happens in refeeding syndrome
Sudden drops in Na, K, Mg and nutrient losses due to sudden increase in carbohydrate levels
Why is enteral feeding preferred
- using the gastrointestinal tract as much as possible.
Enteric villi can start to atrophy if not used leading to bacterial relocation throughout the gut.
Enterocytes require food to function
What is parenteral nutrition
nutrition that can be directly placed within the animals venous circulation.
TPN vs PPN- total/partial
Normally referral skill.
Liquid made up for lipids, amino acids and glucose through a enterally placed catheter.
Catheter could be multi-lumened
fluid therapy and continuous blood electrolyte monitoring should be maintained
Complications with parenteral feeding (4)
Infection at Cather placement site, phlebitis (inflamed vain), hyperglycaemia, hyperlipaemia
How long should assisted feeding be discontinued over
6-12 hrs
Problems with feeding tubes (5)
Blockages
Dislodging of the tube, movement
Trauma
Infection
Over-granulation
How and when to flush feeding tubes
5ml prior to feeding to check tube placement, 10-20ml post feeding to clean out tube, needs to be considered when you think about volume being given
