Dialysis-induced Hyperkalaemia Presenting as Profound Muscle Weakness

We report here two patients with end stage renal disease who developed life-threatening hyperkalaemia during dialysis. Both presented with profound muscular weakness, an uncommon presentation of hyperkalaemia that occasionally serves as a warning of impending cardiac arrest (1). Both patients had been inadvertently dialysed against a dialysate potassium concentration of 10 mmol/L because of an error made by the manufacturer of the concentrate.
