Phase 1 (4 weeks): Observation only. Standard priming/rinsing procedure with isotonic saline Phase 2 (4 weeks): Intervention. Switch to a 5% dextrose solution for priming/rinsing procedure Phase 3 (4 weeks): Switch back to standard priming/rinsing procedure with isotonic saline During the study, blood pressures will be measured in a standardized manner at 2 week intervals, a thirst questionnaire will be completed at the end of each phase, and interdialytic weight gain, in-center pre/post-HD blood pressure and intradialytic symptoms will be recorded, apart for routinely measured parameters.
