Renal Endocrinology Emergency Medicine Standard — correction factor 1.6 mmol/L per 5.5 mmol/L glucose above 5.5
Sodium Correction for Hyperglycaemia
Calculates the corrected (true) serum sodium in hyperglycaemic states (DKA, HHS). Hyperglycaemia causes osmotic dilution of sodium — the corrected value guides fluid resuscitation.
