Central hematocrit (H) measurements are currently used to track the degree of ultrafiltration-induced hemoconcentration with the aim to detect and prevent excessive intravascular fluid depletion during hemodialysis (HD). Failure to maintain hemodynamic stability is commonly attributed to the misinterpretation of H caused by an unaccountable increase in Fcells , the ratio of whole-body hematocrit to H. It was the aim to examine Fcells under everyday conditions in a group of stable HD patients. Absolute plasma volume (Vp ) and H were concomitantly measured during routine HD in the extracorporeal system in hourly intervals by noninvasive and continuous technology (CritLine-Instrument-III) and indocyanine green dye dilution to derive relative plasma volumes from Vp and H (RPVp , RPVH ), respectively, and to calculate Fcells ...

The bioimpedance spectroscopic (BIS) analytical algorithm described in this report allows for the non-invasive measurement of intravascular, interstitial, and intracellular volume changes during various fluid management procedures. The purpose of this study was to test clinical use feasibility and to demonstrate the validity of the BIS algorithm in computing compartmental volume shifts in human subjects undergoing fluid management treatment. Validation was performed using volume changes recorded from 20 end stage renal disease patients...

Anemia treatment in hemodialysis-dependent (HDD) CKD patients involves adequate supply of iron and an erythropoiesis-stimulating agent (ESA). Despite widespread usage of these agents, there is no generally accepted "standard dosing algorithm" for treating anemia in HDD-CKD patients. The new anemia Quality Incentive Program (QIP) introduced by the Centers for Medicare & Medicaid Services represents a motivation to standardize and harmonize iron and ESA regimens with interactive electronic algorithms and novel modes of deliveries for IV iron and ESA doses...

Clinically significant hemolysis is a rare but serious problem in dialysis. Because hemolysis affects red blood cell count and optical density of plasma it has been speculated whether techniques used for online blood volume monitoring would be useful to detect hemolysis. In this study the influence of free hemoglobin on hematocrit and relative blood volume changes measured by optical means (CritLine, HemaMetrics, Kaysville, UT) were examined using an in vitro model with bovine blood. Free hemoglobin solutions were added in steps to circulating whole blood at baseline hematocrits covering a range from 30% to 60% and at blood flows of approximately 200 and 400 ml/min...

Measurement of vascular access flow (QVA) has been suggested as a method of choice for vascular access quality (VAQ) monitoring. Besides traditional duplex Doppler, a number of bedside methods based mostly on the Krivitski principle of QVA evaluation from recirculation at reversed needles (RX), have been developed. This work compares ultrasonic dilution (UD), taken as a reference, HD01, Transonic Systems; duplex Doppler (DD); thermodilution (TD), BTM, Fresenius; optodilutional RX measurement (ORX), Critline III, R-mode, HemaMetrics; direct optodilutional QVA evaluation from jumpwise changes in ultrafiltration rate at both normal and reversed needles connection (OABF), Critline III, ABF-mode; and direct transcutaneous optodilutional QVA evaluation (TQA), Critline III TQA...

Imbalance between cardiac oxygen supply and demand may trigger cardiac events in already vulnerable hemodialysis (HD) patients. We studied the effect of ultrafiltration (UF) and HD in nine chronic HD patients by continuously measuring blood volume (BV; by Critline), blood pressure (BP; by Portapres), and changes in hemodynamics (Modelflow) during isolated UF (iUF) of 500 mL in 30 minutes and subsequent HD combined with UF (HD + UF). Aortic pressure was reconstructed from finger pressure. Changes in cardiac oxygen supply were assessed by calculating the area under the aortic pressure curve during diastole (diastolic pressure time index [DPTI])...

Our department has been using continuous blood volume monitoring (Critline instrument, In-line Diagnostics, Riverdale, USA) for over two years now. First during research on sodium concentration control in haemodialysis (HD), later in the project on assessment and control of hydration in HD patients.

BACKGROUND: Haemodynamic stability in intensive care unit (ICU) patient with acute renal failure (ARF) during intermittent dialytic support has been the focus for several variations to dialysis delivery. Indeed this has been noted by many as a possible cause for prolonged renal dysfunction created by repeated hypotensive renal insult, as well as a reason for the lower delivered dialysis dose afforded. End-stage renal failure patients supported by intermittent dialysis have benefitted from variable sodium dialysate and variable ultrafiltration rate protocols...
