Sodium(meq) required = (desired sodium - actual sodium)*Total body water
Quantity of Sodium required to correct plasm Na+ to desired level
meq Na+
or
ml 3%NaCl
The plasma sodium concentration should be raised by not more than 0.5-1.0 meq/L per h and by not more than 12 meq/L in first 24 h
The desired sodium goal for correction of acute hyponatremia is usually 125 meq/L
The risk of correcting hyponatremia too rapidly is the development of
osmotic demyelination syndrome
