Do We Need to Abandon High Ultrafiltration Rates in America?
By Peter Laird, MD
Dialysis practices around the world differ significantly from the practice patterns observed in America and many have long believed this is in part the explanation for our higher dialysis mortality.
I recently spoke with a manager of a dialysis unit and his experience with horrified Japanese patients who couldn't believe the blood flow rates used in America compared to Japan. Japan, Europe, Australia and New Zealand have long recognized the survival benefits of longer, slower and gentler dialysis compared to our American style violent sessions.
A recent paper looked at the ultrafiltration rates as a marker of survival. In this retrospective analysis of nearly 2000 patients, the authors categorized the patients into three groups: Ultrafiltration rates 10ml/h/kg, 10-13ml/h/kg, and those over 13ml/h/kg. The results are striking:
Rapid fluid removal during dialysis is associated with cardiovascular morbidity and mortality
Compared to ultrafiltration rates in the lowest group, rates in the highest were significantly associated with increased all-cause and cardiovascular-related mortality with adjusted hazard ratios of 1.59 and 1.71, respectively. Overall, ultrafiltration rates between 10

Makes sense really. Thanks for posting this here
