AKI Flashcards
What does AKI mean
Renal failure in 48 hours
Serum creatinine 1.5 times basal
Urine volume lower than 0.5 mL in six hours
What is the difference of RIFLE-AKIN-KDIGO
RIFLE = patient creatinine
AKIN = Basal creatinine
KDIGO refers for 7 days
Main laboratory and clinical symptoms of AKI
Vomiting, tiredness, hypovolemia, hypertension, oligoria, increased, BUN, increased, creatinine hyperkalemia, hyper natremia, hyaline cylinders
Look for ultrasonography
What is the most common acute kidney injury reason?

Volume Depression
What is the most common cause of renal acute kidney injury
Acute tubulointersitsial necrosis
What is the symptoms and laboratory findings pre-renal azotemia?
Hypovolemia,
hypernatremia
hypokalemia,
hypercalcemia,
tachycardia,
Hypertension
BUN > 60
Creatinine > 3
BUN/creatinine > 20
FeNa < %1
FeUr < 30
Osm > 500
Heart failure
Liver failure
Dry mucosas
Thirstiness
What is the treatment of prerenal azotemia
Volume replacement, and treatment of main pathology
What is the most common cause of toxic ATN?
Aminoglycoside,
radio contrast matter
What is the risk factors of AKI?
DM
Hypertension
Age
Cardiac problems
Diuretic user
Dehydration
What phases do ATN have?
Beginning
During == oligouria
Recovery == polyuria
What is the laboratory findings of renal azotemia
BUN > 40
Creatinine > 2
BUN/creatinine >20
FeNa > %2
FeUr > 50
Osm < 350
Dysmorphic RBC ==> BIOPSY
What is the crush syndrome and treatment of it?
Crush syndrome is rhabdomyolysis caused by trauma. The release of myoglobin makes and toxic effect on kidney tubules. That makes toxic ATN.
Treatment is volume replacement with mannitol-alkaline
What is the most common cause of post renal azotemia
Prostate hypertrophy
What is the types of dialysis?
Peritoneal
Slow hemodialysis
Acute hemodialysis
Hemofiltration
What is the treatment of post renal azotemia
Treatment of main pathology
