Summary

Sufferers with kidney failure depend upon dialysis to keep up impartial potassium stability. The quantity of potassium eliminated throughout a hemodialysis therapy is inversely proportional to the potassium focus within the dialysis tub. Nephrologists regulate the dialysis tub potassium to account for particular person variation in potassium consumption amongst their sufferers. This administration technique is remarkably profitable, as a result of most sufferers on upkeep hemodialysis have a standard predialysis serum potassium focus. However the serum potassium focus of sufferers on upkeep hemodialysis will not be fixed over time; it follows a sawtooth sample. It’s this instability–especially the acute fall throughout dialysis–that has involved nephrologists for many years, significantly in view of the essential position of potassium in cardiac electrophysiology. This concern is amplified by the terribly excessive price of sudden dying amongst sufferers on upkeep hemodialysis. On this paper, we overview the security of low-potassium dialysis and make suggestions for managing sufferers whose serum potassium focus falls exterior the goal vary.
