Indications for renal replacement therapy (RRT)

An element of clinical judgement is important here with regards to patient suitability for dialysis and which modality is most appropriate (e.g. intermittent haemodialysis, continuous haemofiltration, haemodiafiltration, etc.). However, RRT should be discussed in the following cases if refractory to first line medical management:

• Severe hyperkalaemia
• Volume overload
• Acidosis (pH <7.2)
• Uraemia complications – e.g. pericarditis, encephalopathy
