The Hypernatraemia CPG has been updated by the CPG Committee.

The Key points for the CPG are

1. Start treatment early with IV sodium chloride 0.9% + glucose 5%
2. The rate of correction should not exceed 0.5 mmol/L/hr, ie 10-12 mmol/L per day, to avoid cerebral oedema, seizures and permanent neurological injury
3. All children with moderate or severe hypernatraemia should have a paired serum and urine osmolality, but this should not delay treatment
