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.
