The dialysis staff workload and the blood volume tracking system during the hemodialysis sessions of hypotension-prone patients.

Purpose: Intradialytic hypotension (IDH) represents a common hemodialysis (HD) complication. Blood volume tracking (BVT) is a tool regulating the relative blood volume changes and potentially reducing the occurrence of IDH. The aim of this study was to evaluate the ability of BVT to reduce the staff workload associated to IDH.

Calcium profiling in hemodiafiltration: a new way to reduce the calcium overload risk without compromising cardiovascular stability.

Background: Low and high dialysate calcium (Ca²⁺) content may have positive and harmful effects depending on the considered pathological aspect: hemodynamic instability, cardiac arrhythmias, parathormone release, adynamic bone disease, cardio-vascular calcifications. We hypothesized that a time-profiled Ca²⁺ concentration would keep the cardiovascular advantages of high Ca²⁺ but would reduce the risk of calcium overload.

Methods: A prospective, multicenter study using a particular hemodiafiltration technique that allows the profiling of electrolytes was designed.

Divert to ULTRA: differences in infused volumes and clearance in two on-line hemodiafiltration treatments.

Background: Mixed diffusive-convective dialysis therapies offer greater removal capabilities than conventional dialysis. The aim of this study was to compare two different on-line, post-dilution hemodiafiltration (HDF) treatments with regard to achieved convective volume and middle-molecule dialysis efficiency: standard volume control (sOL-HDF) and automated control of the transmembrane pressure (TMP) (UC-HDF).

Methods: We enrolled 30 ESRD patients (55.

Simple model of intra-extracellular potassium kinetics and removal applied to constant and potassium-profiled dialysis.

Aim: The incidence rate for sudden death in hemodialysis patients ranges between 2% and 7%. This phenomenon is frequently due to cardiac arrhythmias. In particular, the process of potassium (K(+)) depuration performed during hemodialysis has been found to be related to arrhythmia onset.
