[Acetate dialysate: responsible for decrease in ultrafiltration in continuous ambulatory peritoneal dialysis]

The authors report the follow up of ultrafiltration in 45 chronic renal patients treated by continuous ambulatory peritoneal dialysis from May 1978 to August 1983. 31 patients have been using acetate buffered dialysate, 14 patients lactate buffered dialysate. Ultrafiltration obtained with acetate fluid has always been less important compared with lactate fluid (p less than 0,001). This decrease has been observed in all the acetate patients and has worsened as a function of duration of treatment, whereas it has only been observed in 14,3% of the lactate-dialysed patients.
