High flow peritoneal dialysis.
We have developed a catheter extension/continuous ambulatory peritoneal dialysis (CAPD) set (ANDY high flow set) of larger lumen (minimum internal diameter 3.25 mm), and compared peritoneal dialysate flow rates in two groups of 6 stable CAPD patients of comparable age, sex distribution, and time on dialysis according to type of catheter. Both groups were studied with two different extension/sets, standard ANDY and ANDY high flow set. The shortest infusion time was observed with the combination Cruz catheter/ANDY high flow set. The switch to a high flow set decreased significantly the inflow time of both types of catheter, and the infusion time of the Tenckhoff catheter/ANDY high flow combination approximated that of the Cruz/ANDY combination. Likewise, the dialysate outflow rates were highest with the Cruz catheter/ANDY high flow set than with any other catheter/set combination (p = 0.005). This was apparent, not only in the total outflow time, but also in the vol/min during the first 4 min (p = 0.005). None of the patients experienced discomfort during the dialysis exchanges with the high flow system. This combination of Cruz catheter/high flow set effectively reduces the dialysis exchange time and is very much appreciated by the patients.
