35yo male with longstanding CRF.

Weeks of moderate abdominal pain with acute exacerbation.

Now depressed LOC/obtundation with acute abdomen & hypotension.

 

NB: you might reasonably think these aren't real (we did):


CRF + GI Bleed/Perforation + Pancreatitis
  • longstanding CRF and DU → self-medication with alkali
  • acute perforation → peritonitis + GI Bleed + pancreatits
  • hypovolaemia / anaemia / hypotension
    → added AKI & severe metabolic acidosis (acute on chronic)
  • life-threatening hyperkalaemia

Urea/Creatinine:

NB: hyperkalaemia:

  • to survive [K+] > 10, his baseline must be high → smaller proportional rise
    e.g. baseline ≈ 6 → 11 represents a < 2x increase
  • you could argue the rate of correction (see serial image) was way too fast
    → correction to [K+] ≈ 3.5 mmol/L within 36 hours carried a high risk of arrhythmia
  • CRRT should have been aiming for 'high-normal ', e.g. dialysis [K+] ≈ 5-6 mmol/L
