Treatment of hyponatremia is as following-
1. Depletional hyponatraemia-
i) IV infusion of Normal saline (0.9% NaCl). If serum Na+ concentration is less than 125 mmol/L- 3% NaCl solution is given IV at a rate of 6-8 drops per minute
ii) Treatment of underlying cause.
2. Hyponatraemia with normal ECF-
i) Water restriction
ii) In case of severe hyponatraemia – loop diuretics and hypertonic solution are used.
3. For dilutional hyponatraemia-
i) Restriction in Na+ and water intake
ii) 20% manitol- 100 ml to increase renal water excretion
iii) Treatment of underlying cause
N.B Calculation for Na+ requirement (in mmol) of the body-
(125 – measured Na+) — 0.6 X body weight in Kg.
