Info

Increased

? Less arrhythmias, ? hemodynamic benefit

Potential for hypermagnesemia

Decreased

Permits greater use of magnesium containing phosphate binders which in tum permits reduced dose of calcium binders and results in less hypercalcemia

Symptomatic hypomagnesemia

Plasma potassium concentration can be expected to fall rapidly in the early stages of dialysis, but as it drops, potassium removal becomes less efficient [17,18]. Since potassium is eely permeable across the dialysis membrane, movement of potassium from the intracellular space to the extracellular space appears to be ' limiting factor that accounts for the smaller fractional decline in potassium concentration at lowei plasma potassium conceiiliallous.
