Ultrafiltration in patients on automated peritoneal dialysis with Homechoice Claria connected to Sharesource: A pilot
Introduction:
Fluid overload is an unavoidable problem in patients on peritoneal dialysis (PD) and is associated with poor outcomes. The aim of our study was to estimate ultrafiltration (UF) under different dextrose concentrations (DCs) and four peritoneal transport levels.
Materials And Methods:
70 patients, with a total of 1,848 daily treatment records and 8,266 single dwells on automated PD (APD) through Homechoice Claria with Sharesource were followed in October 2020 and categorized into two groups according to the DC (D1.5% and D2.5% groups). Baseline characteristics, peritoneal membrane characteristics, and daily PD treatment records from Sharesource were obtained. We compared UF under the different conditions.
Results:
The mean night UF per cycle, the mean night UF corrected by fill volume (FV) per cycle, and the mean night UF corrected by FV and dwelling time (DT) per cycle were all significantly higher in the D2.5% group than in the D1.5% group (95.8 vs. 220.3 mL, 5.5 vs. 12.0%, and 5.0 vs. 11.6 0/000/minutes, all p < 0.001). However, there was no significant difference among the four transport categories in any group.
Conclusion:
This retrospective study presents precise UF measurements with two solutions at different DCs and four peritoneal transport levels. With a 2-L indwell (DT ranging from ~ 1 to 3 hours), the mean net UF rate was 1.0 mL/min in the D1.5% group and 2.3 mL/min in the D2.5% group.
