Caused partly by renal failure but mainly by comorbidities.

Transfusion agents may be required.

variable
high

Results in ECG abnormalities (i.e., peaked T waves, increased PR interval, widened QRS, atrial arrest, and deterioration to a sine wave pattern) and cardiac arrhythmias.

Hyperkalaemia may be treated by restriction of dietary intake, potassium binding ion exchange resins, and loop diuretics.

Emergency measures for this include intravenous insulin and glucose, and haemodialysis.

If hyperkalaemia is refractory to medical treatment or if cardiac manifestations are present, haemodialysis is indicated for rapid potassium normalisation.

variable
high

Caused by renal impairment.

Oral bicarbonate preparations such as sodium citrate/citric acid may be used to manage metabolic acidosis.

Management often requires dialysis if severe and if respiratory compensation is unable to maintain pH.

variable
medium

Severe kidney injury, especially in patients with underlying kidney disease or other comorbid medical conditions; may not recover and renal replacement therapy may be required.

variable
low

Caused by dysfunction of platelets due to uraemia.

Requires treatment with desmopressin, oestrogens, correction of anaemia, and dialysis.

variable
low

Uraemic toxins accumulate with severe and untreated renal failure resulting in lethargy and confusion. Pericarditis may develop.

Dialysis is required for management of uraemia.
