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...
متن کاملSerum 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...
متن کاملThe efficiency of potassium removal during bicarbonate hemodialysis.
Patients on chronic hemodialysis often portray high serum [K+]. Although dietary excesses are evident in many cases, in others, the cause of hyperkalemia cannot be identified. In such cases, hyperkalemia could result from decreased potassium removal during dialysis. This situation could occur if alkalinization of body fluids during dialysis would drive potassium into the cell, thus decreasing t...
متن کاملThe faster potassium-lowering effect of high dialysate bicarbonate concentrations in chronic haemodialysis patients.
BACKGROUND Hyperkalaemia is common in patients with advanced renal disease. In this double-blind, randomized, three-sequence, crossover study, we compared the effect of three dialysate bicarbonate concentrations ([HCO3-]) on the kinetics of serum potassium (K+) reduction during a conventional haemodialysis (HD) session in chronic HD patients. METHODS We studied eight stable HD patients. The c...
متن کاملHypoxemia during hemodialysis: effects of different membranes and dialysate compositions.
Hypoxemia during hemodialysis: Effects of different membranes and dialysate compositions. Arterial oxygen tension (Pa02) and white blood cell (WBC) count decrease during hemodialysis (HD) when certain types of membranes are used. Two mechanisms, impaired gas exchange due to intrapulmonary leucostasis and alveolar hypoventilation, have been proposed. To gain more insight into their respective ro...
