Abstract
To determine the contribution of dialysate to hemodynamic changes that occur during hemodialysis, echocardiographic measurements obtained during identical conditions of hemodialysis except for the use of different dialysates were compared. With an acetate-buffer systolic blood pressure and arterial O2 tension declined but mean rate of left ventricular fiber shortening increased. These changes occurred after only 15 min of hemodialysis. With a HCO3- buffer these alterations did not ensue. During hemodialysis with limited ultrafiltration, the fall in arterial pressure observed is caused by the acetate-buffer. In hemodynamically unstable patients, HCO3- may be the preferable dialysate.
