Summary

Establishing the euvolemic state in hemodialysis patients -the so called "dry weight"- is an important clinical conundrum in every nephrologist's daily practice. Underestimation of dry weight (with excessive ultrafiltration) results in dialysis-induced hypotension. Currently used methods to establish dry weight, including clinical assessment, bio-impedance spectroscopy and online relative blood volume (RBV) measurements, all have their limitations. RBV measurement reflects changes in blood volume during dialysis without providing any information about the initial hydration status, or the initial absolute blood volume (ABV). Recently, researchers proposed a new method to calculate ABV, by using the principle of dilution-indicator with RBV measurement. In a small cohort study they identified a total blood volume threshold of 65 millilitres per kilogram dry weight predicting for intra-dialytic hypotension associated symptoms. The goal of current clinical trial is to re-investigate the accuracy of the above-described method and to confirm the hypothesis of a critical threshold of 65 ml blood volume per kg dry weight in haemodialysis patients. Researchers will compare adjustment of dry weight based on the ABV measurement with standard care to see if dialysis-induced hypotension will be reduced.
