Acute Kidney Injury Flashcards
1
Q
methods of detecting and monitoring AKI
A
measuring serum creatinine (rapid rise)
fall in urine output
fall in eGFR
2
Q
which type of AKI is most common (pre-renal, renal, post-renal)
A
pre renal - 90%
3
Q
how can NSAIDs cause AKI
A
result in renal hypoperfusion
4
Q
what type of AKI does eclampsia cause
A
renal
5
Q
clinical definition of AKI
A
- rise in serum creatinine of 26umol/L or greater within 48 hours.
- 50% or greater increase in serum creatinine (1.5 fold from baseline) within the preceding seven days.
- A fall in urine output to less than 0.5 mL/kg/hour for more than six hours.
6
Q
how does urine output change in AKI
A
usually decrease or nothing
may increase due to reduced fluid reabsorption or osmotic effect of accumulated metabolites
7
Q
symptoms of AKI
A
confusion
dehydration
nausea
vomiting
urine output changes
8
Q
what things can help differentiate CKD from AKI
A
CKD =
long duration of symptoms
nocturia
absence of acute illness
anaemia
hyperphosphataemia
hypocalcaemia
reduced renal size on USS
