Successful management of severe hyponatraemia during continuous renal replacement therapy

Rapid correction of chronic hyponatraemia can lead to osmotic demyelination syndrome. Ensuring a gradual correction can be difficult, especially in patients on renal replacement therapy (RRT). A 43-year-old renal transplant patient presented with severe chronic hyponatraemia. She required continuous RRT. The hyponatraemia was corrected successfully by manually adjusting sodium concentration in the dialysate. Our case describes an effective method to ensure severe hyponatraemia is corrected safely during continuous RRT.
