Abstract
The evaluation of hemodialysis ultrafiltrate is essential for the assessment of uremic toxins, dialyzer net performance, protein catabolic rate, and safety and environmental protection. Total dialysate collection (TDC), however, is technically far from the daily procedure used. In the present study, use of a continuous syringe extraction method (CSEM) as a substitute for TDC was tested to determine its comparative effectiveness. Measurements of urea nitrogen, creatinine, phosphate, beta2-microglobulin, and albumin were simultaneously obtained by both TDC and CSEM in 20 dialysis sessions. CSEM showed an extremely significant correlation with TDC for these values. The correlation coefficients were >0.97 for these indicators and the value of Fisher's r to z were all <0.001. Taken together, these data indicate that CSEM is an effective substitute for TDC. With use of CSEM, the evaluation of spent dialysate could become as a daily procedure.
