Dry Weight Reduction Intervention Via Extra Ultrafiltration
University of Washington
Summary
Most patients who receive hemodialysis treatments have excess fluid in their body that has slowly built up over the course of kidney disease. This extra fluid is the main cause of high blood pressure in dialysis and leads to stress on the heart and lungs.that causes debilitating symptoms and frequent hospitalizations. This trial will test whether a focused program of 4 or 8 weeks of extra ultrafiltration treatments can remove most of this extra fluid. We believe that getting rid of large amounts of extra fluid will result in sustained improvements in blood pressure and symptoms. Ultrafiltration is a gentler type of dialysis that removes fluid but does not clean the blood.
Description
This is a randomized trial of patients who are receiving in-center hemodialysis treatments for end stage kidney disease and have clinical suspicion of fluid overload. Enrolled participants will be randomly assigned in 1:1:1 fashion to either a four-week ultrafiltration strategy, an eight-week ultrafiltration strategy, or continuation of their regular thrice weekly hemodialysis treatments. Each ultrafiltration strategy will add two extra four-hour ultrafiltration treatments per week plus pharmacist-guided tapering of blood pressure medications. We will test the impact of these strategies on pri…
