Indications for dialysis
S/S of kidney failure
Inability to control volume status or BP
Progressive deterioration in nutritional status or cognitive impairment
EGFR between 5-10 ml/min
Symptoms of kidney failure
Serositis, acid-base or electrolyte abnormalities, pruritis
mnemonic for acute dialysis indications
AEIOU (acidosis, electrolyte abnormalities, intoxication overload of volume, uremia)
When can acidosis be considered
PH <7.2
Mnemonic for intoxication for acute dialysis indication
SLIME: salicylates, lithium, isopropanol, methanol, ethylene glycol
What is uremia in renal failure
buN > 100 mg/dL, extreme anorexia, pericarditis
What form of dialysis is used most often for membrane: Low flux, high efficiency, or high flux
High flux: it is capable of removing high molecular weight substances (vancomycin)
Greater clearance of water/substances = shorter treatment time
What are reasoning HD may be inadequate
Patient compliance, low blood flow rates, stenosis or thrombosis
Catheters
What are 2 options to increase urea clearance
Larger membrane, increased treatment time
Medications for hypotension in dialysis
Midodrine, droxidopa, fludrocortisone
Midodrine MOA and onset
Arteriolar and venous tone resulting in a rise in standing, siting and supine BP
Onset: 1 hour
Droxidopa MOA
Metabolized by catecholamine pathway to norepinephrine, results in vasoconstriction of peripheral
veins and arteries
