Learn how to calculate the free water deficit in hypernatremia using serum sodium concentration and total body water. The formula is FWD = TBW x (serum [Na] -140) / 140; TBW = wt (kg) x 0.6 (male) or 0.5 (female).

The Free Water Deficit is calculated in hypernatremia and determines the volume (L) of water required to correct dehydration or, to reach the desired level of sodium in the blood serum, during the initial stages of fluid-replacement therapy.

Free water deficit – hypernatremia. Hypernatremia reflects a deficit in the total amount of water in the body in relation to the total sodium content. The free water deficit is used to access the amount of water replacement needed to correct hypernatremia.

Calculation. Calculate Water deficit. Total body water x (serum Na-140)/ (140) TBW is usually 50% in males and 40% in females; So male with Na of 160 has free water deficit of (0.5 x 70) x 20/140 = 5 Litres; Aim to replace deficit plus maintenance and ongoing losses; Replace with oral free water or 5% dextrose over 24-48 hours
