nutrition Flashcards
What are the 4 different types of malnutrition?
decreased nutrient intake, malabsorption, increased energy requirements, or all above
What are the consequences of malnutrition?
Consequences: micronutrient deficiency, muscle wasting, increased falls, inactivity, immobility also means greater chance of infections, weaken immune system, wounds healed less quickly
How do you score MUST?
BMI (18.5-20 =1 or <18.5 =2) wt loss (5-10% =1 or >10%=2) acute disease effect (pt ill and likely to be intake for >5 days)
At what MUST score do you intervene with malnutritioned pts?
Score over 2 - monitor feeding and wt
If 1 monitor food intake for 3 days
What are the different lines of mx for MUST?
1st line: food - snacks, nourishing drinks and food fortification eg fortisip
2nd line: nutrient supplements -liquid, powder, semi solid - micro and macro
3rd line: enterol via PEG or NGT -
4th line: parenteral - food via central line
+ves and -ves of eneterol mx?
+ves: direct feeding into gut, preserves gut mucosa and integrity as still being exposed to food and digesting - less expensive than perenterol
-ves: can get nausea, early satiety, constipation, diarrhoea, uncomfortable to place
How do you check a NGT is properly in place?
1st line: acid pH aspirate to check in stomach - aims pH less than 5.5; 2nd line: CXR
What is the difference between naso jejunal and NGT?
Naso jejunal - decreased gastric emptying or pancreatitis so want to avoid stomach, less than 60 days use, radiologically guided, can’t check with pH
What is an indication of a naso jejunal tube?
indications: dysphagia, CF (higher nutritional requirements), inadequate nutritional intake
What is a pharnygeal pouch?
hernia, that occurs in the pharynx.
sx: dysphagia, regurgitation, halitosis, chronic cough, hoarse voice, wt loss, aspiration, lump
What is refeeding syndrome?
Shift use energy stores from fat met to carb met -> insulin -> increased cellular uptake K, phosphate and mg -> Shift fluids and electrolytes -> fluid retention, cardiac arrhythmias, resp insufficiency death
What is the mx of refeeding syndrome?
Mx: BEFORE FEED for first ten days give IV thiamine and other vit Bs then slow introduction of nutrition, daily monitor refeeding blds: U+Es, phosphate, Mg
