Recognises and manages the patient with, or at risk of, acute renal failure
A patient with polytrauma develops compartment syndrome with an ischaemic leg 24hrs into his admission. He undergoes revascularisation and fasciotomies, but develops rhabdomyolysis and acute kidney injury with a CK that peaks at over 100,000.
Is there a role for mannitol and bicarbonate in the management of his rhabdomyolysis and AKI?Read More »
A 55 yr old man developed severe necrotizing pancreatitis with multiorgan failure. One week into his illness he had developed multiple intra-abdominal collections and had high intra-abdominal pressures. Initial conservative management failed, percutaneous drainage of his collections failed to reduce the abdominal pressures, and he underwent decompressive laparotomy.
What is the evidence behind the current guidelines for the measurement of intra-abdominal hypertension and the use of decompressive laparotomy in the management of Abdominal Compartment Syndrome?Read More »
A 65 year old woman underwent an elective mitral valve repair (MVR) and four vessel coronary artery bypass graft (CABG) procedure. Pre-operatively she was diagnosed with chronic kidney disease (CKD) secondary to hypertensive nephropathy, and chronic airway disease secondary to smoking. Her baseline creatinine was 275. Surgery was uneventful but in the post-operatively period she developed pulmonary oedema and worsening acute kidney injury (AKI). On day 2 her creatinine reached 420 and oliguria occurred (urine output < 0.5 ml kg-1 hr-1). Non-invasive respiratory ventilation provided adequate support and maintained a normal blood PaCO2 and pH, although her base excess drifted to -7 mmol l-1.Dopamine was administered at 2–10 μg kg-1 min-1, titrated to MAP ≧ 75 mmHg; pericardial pacing continued to maintain sinus rhythm at 60 bpm; her CVP was 14 mmHg and stable. Furosemide was started and given by a continuous infusion of 10 mg hr-1 after an initial bolus of 100 mg to try and help with diuresis.
Is there any evidence to support the use of loop diuretics in acute kidney injury?
A 35 year old was admitted following a simultaneous kidney pancreas transplant. The procedure had been complicated and she had received a large volume transfusion and crystalloid infusion.Her initial intraabdominal pressures were elevated at 22cmH2O on admission to the intensive care. It continued to escalate over the next 48 hours peaking at 29. She was managed with sedation, NG tube and abdominal perfusion pressures kept above 60mmHg. The tranplanted pancreas remained functional, but the renal transplant showed delayed graft function. On day 4 there was a reduction in her abdominal pressure and her urine output correspondingly increased.

A young man was presented to ED with confusion and a profound metabolica acidosis after ingesting around 400ml of ethylene glycol-based anti-freeze. His GCS deteriorated and he required intubation. He was commenced on iv ethanol and commenced on haemodiafiltration. He initially had a polyuric acute kidney injury, but became anuric after 24 hours. His acidosis normalised within 36 hours, and his creatinine peaked at 549. His urine output improved after a week of oligoanuria and his creatinine reached a baseline of around 150.
