Successful treatment of severe hyponatremia in a patient with renal failure using continuous venovenous hemodialysis.

Both hyponatremia and its rapid correction can cause neurological disorders. Slowly correcting hyponatremia (especially when asymptomatic) at a rate of 0.5 mEq/L/h is recommended; however, little information exists about treatment of hyponatremia in patients requiring dialysis. We report a case of successfully treated hyponatremia using continuous venovenous hemodialysis with a specially prepared dialysate containing a lower than usual sodium concentration.
