what investigations should be done for AKI?

Bloods: FBC, U+E, LFT, glucose, clotting, Ca, ESR
􏰀 ABG: hypoxia (oedema), acidosis, ↑K+
􏰀 GN screen: if cause unclear
􏰀 Urine: dip, MCS, chemistry (U+E, PCR, osmolality, BJP)
􏰀 ECG: hyperkalaemia
􏰀 CXR: pulmonary oedema

in pre renal failure, is urine dilute or concentrated?

concentrated

6

is Na conc of urine in pre renal failure high or low?

low <20mM

7

what is ESRF?

complete loss of function >3months

what is the GFR at each stage of AKI?

reduced GFR of
Risk = 25%
Injury = 50%

severe metabolic acidosis
poisoning

13

how does urea affect bleeding?

impairs haemostasis so increases risk of bleeding
