Q

What is important to determine/what are the priorities in someone with an AKI?

A
  1. Volume assessment and fluid challenge 1L saline over 2 hours, assess urine output
  2. Stop all nephrotoxic drugs
  3. Is the patient septic? (pyrexia, high CPR, leucocytosis)
  4. History: hypertension, diabetes, prostatism, haematuria
  5. Urgent ultrasound scan - look for obstruction, blood flow, size, cysts, symmetry
  6. Urinalysis and microscopy to look for red or white cell casts, myoglobinuria and haematuria
17

18
Q

What are the renal (parenchymal) causes of AKI? (7)

A
  1. Vasculitis (SLE)
  2. Glomerulonephritis
  3. Acute tubular necrosis (ishcaemia, septicaemia, toxins, drugs, malaria)
  4. Thrombotic microangiopathy
  5. Scleroderma crisis
  6. Sepsis
  7. Calcium, urate, oxalate overload
19
Q

What are the post-renal causes of AKI? (5)

A

  2. Increased intra-abdominal pressure
  3. HIV drugs (indinavir)
  4. Ureteric stones/tumour
  5. Urethral - prostatic hypertrophy
20
Q

  2. Assess volume status, measure CVP
  3. Sepsis screen
21
Q

In the management of AKI, what is the treatment for hyperkalamia? (3)

A
