Hypernatremia
Hypernatremia
risk of cerebral oedmema with correction
Slow correction with hypotonic saline RELATIVE to the patient
this might be 0.9% while they are severly hypernatremic
Aim to correct at rate no faster than 0.5 mmol/L per hour
free water deficit = (4 mL x weight in kg) x (desired change in plasma Na)
ie 4ml/kg/mmol of Na drop required
