The new Hypermagnesaemia CPG adds to the existing electrolyte disturbance topics that have been developed by the CPG Committee. Other new topics are Electrolyte abnormalities and Hypomagnesaemia.

The Key points for the CPG are

1. Hypermagnesaemia is frequently an asymptomatic laboratory diagnosis finding
2. Cease any magnesium-containing medications or intravenous solutions. Ask about non-prescribed supplements that may contain magnesium
3. Specialist advice should be sought for symptomatic children with hypermagnesaemia
