GI symptoms of AKI
anorexia, N/V, altered taste acuity, gastroenteritis, peptic ulcers, ascites
how does AKI impact glycemic control?
insulin resistance > hyperglycemia
what impact does AKI have on electrolytes?
-dysnatremia
-hyperkalemia
-hyperphos
-hypocalcemia
what acid base disorder can AKI cause?
metabolic acidosis
how is metabolism impacted in AKI?
hypermetabolic and hypercatabolic
what electrolytes does HD dialysate contain that can be adjusted as needed?
Ca, K, Na, bicarb
which type of dialysis between PD and HD has least restrictive diet?
PD
why can hypokalemia occur in PD patients?
most commercially available solutions do not contain K and PO K supplementation may be needed to prevent/treat hypokalemia
how much protein can be lost each day via PD?
5-24 g/day
estimated absorption rate of dextrose/kcals from CAPD vs CCPD
CAPD: 50-60%
CCPD: 60-70%
CKD (non-dialysis) calorie and protein needs
25-35 kcal/kg
0.55-0.8 g/kg (1 g/kg in illness)
PD and HD calorie/protein needs
30-35 kcal/kg (including dialysate kcals)
>/= 1.2 g/kg
CRRT calorie and protein needs
30-35 kcal/kg
1.5-2.5 g/kg
AKI calorie and protein needs
20-30 kcal/kg
0.8-1 g/kg (non catabolic AKI without dialysis)
1-1.5 g/kg (AKI on RRT)
fluid restriction for anuric pt with AKI
1-1.2 L/day (reflects insensible losses)
which components of RRT may provide additional kcals?
glucose (3.4 kcal/g), lactate (3.62 kcal/g), citrate (3 kcal/g)
anuric definition
UOP <50 mL/day
oliguric definition
UOP 50-500 mL/day
micronutrients of concern in CRRT
zinc, selenium, copper, vitamin C, thiamine, folic acid, vitamin B6, carnitine
does calcitriol production progressively increase or decrease as CKD progresses?
decreases
PTH is secreted in response to…
low serum calcium
why does acidosis occur in AKI and CKD?
because of loss of normal acid excretion or loss of bicarbonate
*can also lead to hyperkalemia
vitamin C dose for adults receiving RRT
100 mg/day
why is excess accumulation of trace elements that are normally excreted renally unlikely during kidney disease?
because losses also occur through GI tract
