Q

refeeding syndrome

A
  • EN: start @ 25% of energy needs and increase over 3-5 days
  • PN: start dextrose @ 25-50%
  • monitor Ph, K, Mg
  • fluid retention, cardiac dysfunction, respiratory failure
  • high risk: chronic malnutrition, prolonged hypocaloric feeding, NPO>7d, chronic alcoholism, anorexia nervosa

Q

nausea, vomiting, abdominal distention, bloating

A
  • continuous feed with low fat and/or isotonic formula
  • consider prokinetics
  • consider change to post-pyloric
  • minimize narcotics, if able

Q

diarrhea

A
  • evaluate medications (sorbitol, magnesium-containing, laxatives, lactulose, etc)
  • evaluate for usage of abx
  • check stool for c.diff or infection
  • provide anti-diarrheals if appropriate
  • observe proper hang times, change tubing, use closed system (food safety)
  • consider change in fiber content of formula
  • consider change to elemental or semi-elemental formula
  • adjust formula to lower fat or higher MCT content; consider panc enzymes

Q

constipation

A
  • increase free water/fluid intake
  • consider change in fiber content of formula
  • increase activity, if able
  • minimize narcotics, if able
  • add stool softeners +/- laxatives
  • trial of prune juice
  • evaluate and address underlying cause - may need to hold EN

Q

hyponatremia

A
  • change to concentrated formula, restrict fluids
  • supplement with sodium
  • restrict fluids/free water; diuresis
  • may be due to SIADH, excess Na losses

Q

hypokalemia

A
  • may be due to refeeding
  • decrease to 25% of goal rate + replete potassium
  • may need to change formula

Q

hyperphosphatemia

A
  • consider change to low Ph formula or recommend phos binders
  • recommend potential change to meds
  • may be due to renal function, tumor lysis, phosphate containing antacids

Q

avoid holding EN for gastric residuals less than

A

500ml

if <250ml - no action
if >250ml - consider prokinetics
if >500 - hold EN and perform physical assessment, evaluate glycemic control, consider prokinetic, minimize narcotics

17
Q

metabolic complications of PN

A
  • impaired glucose tolerance
  • hepatobiliary complications (steatosis, cholestasis)
  • renal dysfunction
  • bone mineral disease
  • potential toxicities/deficiencies
  • catheter occlusion, venous thrombosis, catheter breakage
  • infection: tunnel, catheter sepsis, catheter related bloodstream
18
Q

PN in palliative care

A
  • severe bowel obstruction, short bowel syndrome, malabsorption
  • *if expected survival of several months or at least 6 wks or if malnutrition would cause death prior to disease progression; esp if receiving treatment
19
Q

artificial hydration in palliative care

A
  • may be appropriate, esp if patient is receiving treatment because it can decrease side effects and improve QoL, reduce ER visits
20
Q

artificial hydration in hospice

A
  • inappropriate, may decrease QoL
21
Q

EN in palliative care

A
  • may slow nutritional deficiency, prevent dehydration, improve QoL (in H/N)
  • not generally recommended for terminal stage CA due to risk of complications
22
Q

use of EN/PN in palliative care - cutoffs for PS scores

A

use not justified for:
Karnofsky score <50% or
ECOG score >2
