Hyperkalaemia Management

1. Protect the heart: 

  • Give calcium gluconate 10% IV over 3 mins.

2. Shift potassium back into cells:  

  • 10u insulin in 100mls 20% glucose over 30mins via volumetric pump.

  • Consider salbutamol nebulisers.

  • Sodium bicarbonate if acidaemia is present.

  • Remove potassium from body:

    • If hyperkalaemia persists will likely need dialysis / haemofiltration

3. Monitor potassium and glucose :

  • Monitor at baseline, 60, 120, 240 & 360 minutes for minimum of 6 hours.

  • Monitor for hypoglycaemia.

  • To prevent recurrence and stop further potassium accumulation, consider the following:

    • Low K+ diet, avoid drugs know to raise K+, treat hypotension, ensure the patient is adequately hydrated, consider loop diuretics, K+ removal from gut via administration of the drug calcium resonium.

Stop and think!

Severe hyperkalaemia can result in a fatal arrhythmia - emergency treatment is indicated.
