Dialysate Potassium, Dialysate Magnesium, and Hemodialysis Risk

Serum and dialysate potassium concentrations and survival in hemodialysis patients.

BACKGROUND AND OBJECTIVES Controlling serum potassium is an important goal in maintenance hemodialysis patients. We examined the achievement of potassium balance through hemodialysis treatments and the associated fluctuations in serum potassium. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A 3-yr (July 2001 to June 2004) cohort of 81,013 maintenance hemodialysis patients from all DaVita dial...

Dialysate Composition in Hemodialysis and Peritoneal Dialysis

The goal of dialysis for patients with chronic renal failure is to restore the composition of the body’s fluid environment toward normal. This is accomplished principally by formulating a dialysate whose constituent concentrations are set to approximate normal values in the body. Over time, by diffusional transfer along favorable concentration gradients, the concentrations of solutes that were ...

Review of dialysate calcium concentration in hemodialysis.

The dialysate calcium (Ca) concentration for hemodialysis (HD) patients can be adjusted to manage more optimally the body's Ca and phosphate balance, and thus improve bone metabolism as well as reduce accelerated arteriosclerosis and cardiovascular mortality. The appropriate dialysate Ca concentration allowing this balance should be prescribed to each individual patient depending on a multitude...

Emergency hemodialysis using lactate-buffered dialysate.

Hemodynamic behavior during hemodialysis: effects of dialysate concentrations of bicarbonate and potassium.

BACKGROUND/AIMS Ultrafiltration that occurs during hemodialysis (HD) promotes profound alterations in a relatively short period of time. The dialysate content of bicarbonate (DBic) and potassium (DK) may have impact over intradialytic hemodynamics, which goes beyond ultrafiltration, and its impact was evaluated in a prospective cohort. METHODS 30 patients under HD were submitted to hemodynami...
