Variability of Predialytic, Intradialytic, and Postdialytic Blood Pressures in the Course of a Week:A Study of Dutch and US Maintenance Hemodialysis Patients

Background: Patients with thrice-weekly hemodialysis have higher predialysis weights and ultrafiltration rates at the first compared with subsequent dialysis sessions of the week. We hypothesized that these variations in weight and ultrafiltration rate are associated with a systematic difference in blood pressure. Study Design: Observational study. Setting & Participants: During 3 months, we prospectively collected hemodynamic data for 4,007 hemodialysis sessions involving 124 Dutch patients. A similar analysis was performed with 789 US patients, comprising 6,060 hemodialysis sessions. Fac... Mehr ...
