5

Give three ways that you can get pre renal acute kidney injury?

1. Hypovolaemia from d&v/burns
2. Hypotension from sepsis, cardiogenic shock or anaphylaxis
3. Reanl Hypoperfusion due to NSAIDS, ACE, ARBs on a background of poor kidney function and possible a "sick day"

6

Give three causes of acute tubular necrosis?

Untreated pre renal AKI
Rhabdomyolisis
Drug toxicity

7

How do you treat pre renal AKI?

Fluid challenge (0.9% saline)

8

What is the definition of renal AKI?

Disease causing inflammation or damage to the kidney cells causing acute kidney injury.

9

What structures can be damaged in renal AKI?

Blood vessels
Glomerular disease
Interstitial injury
Tubular injury

10

List 6 specific caused of renal AKI?

Vascular
- Vasculitis
Glomerular
- Glomerulonephritis
Interstiaial nephritis
-Drugs
- infection (TB)
- sarcoidosis
Tubular injury
- Ischaemia due to prolonged renal hypoperfusion
- Gentamicin
- Contrast study
- Rhabdomyolysis

11

What antibodies would you expect to find in SLE?

ANA

12

What antibodies would you expect to find in vasculitis?

ANCA

13

What antibodies would you expect to find in goodpastures?

GBM antibodies

14

How would you treat renal AKI?

1. Fluid resuscitate
2. If still not at adequate BP then inotrpes or vasopressors
3. Treat underlying cause
eg antibiotics if septic
4. Stop nephrotoxic drugs
5. Dialysis if they are anuric and have uraemia.

15

How do you get post renal AKI?

Due to an obstruction (eg stone, stricture) obstructing the urine flow and causing hydronephrosis with reduces the concentrating ability of the kidney

16

How do you treat post renal AKI?

Relieve obstruction
Catheter
Nephrostomy

17

What counts as hyperkalemia?

Pottassium above 5.5

18

What counts as life threatning hyperkalaemia?

above 6.5
