Effect of Lowering the Dialysate Sodium on Blood Pressure in Hemodialysis Patients
Phase 3
Completed
- Conditions
- Hemodialysis
- Interventions
- Other: Lowering the dialysate sodium
- Registration Number
- NCT00724633
- Lead Sponsor
- Lawson Health Research Institute
- Brief Summary
Patients currently receiving hemodialysis will be randomized to receive 1 of 3 dialysate sodium prescriptions. The effects on blood pressure, interdialytic weight gain, thirst, and intradialytic symptoms will be assessed.
