Three exchanges with a 2.5-liter volume for continuous ambulatory peritoneal dialysis

摘要: Continuous ambulatory peritoneal dialysis (CAPD) is the continuous presence of solution in cavity except for brief periods fluid exchanges. Long-dwell exchanges allow equilibration small molecular-weight solutes between plasma and dialysate, so that clearances these are essentially equal to drainage volumes a particular period. Originally five with 2 liters were used, yielding daily 10.9 11.7 [1]. Oreopoulos et al [2] found four 2-liter per day sufficient most patients achieve good biochemical control uremia. Increasing volume instilled into would augment efficiency same frequency or number be reduced yet retain efficiency. In present study, we used three 2.5 solution. Mainly concentrations glucose used: 1.5%, 2.4%, 3.3%. Occasionally, 4.2% concentration was used. The total exchange time (diffusion time, cycle time) varied from 14 hours. aim this preliminary study ascertain whether such could tolerated by yield ultrafiltration.
