The purpose of this randomized controlled study is to compare the effects of different new dialysis on-line monitoring devices on hemodynamic stability during intermittent hemodialysis in critically ill patients with acute kidney injury.
Acute kidney injury (AKI) is associated with high mortality and morbidity rates in critically ill patients despite advances in renal replacement therapy (RRT). Over the last few years, new devices in dialysis equipment, such as blood temperature and blood volume on-line monitors, have been developed to improve hemodynamic tolerance, and these new modalities have demonstrated their positive impact on decrease in intra-dialytic hypotension rate in chronic hemodialysis patients. In order to evaluate these new devices in critically ill patients with acute kidney injury we decided to conduct a prospective randomized controlled trial.
We based calculation of the sample size on a power analysis that assumed an expected decrease in intra-dialytic hypotension rate of 40% (from a crude intra-dialytic hypotension rate of 30% to 18%) in groups B and C, compared with group A. Analysis is done by intention to treat, according to prescribed new dialysis on-line monitoring devices.

This prospective, randomized, controlled study aims to evaluate the usefulness of the new body composition monitor (BCM) device as a method to improve volume control in hemodialysis (HD) p...
The main objective is to establish a statistical predictive model of the risk of intradialytic hypotension during hemodialysis (HD) or hemodiafiltration (HDF) sessions based on the measure...
More than 80% of patients with end stage renal disease have hypertension; 70% of whom are poorly controlled using conventional Hemodialysis therapy. An expanded extracellular fluid volume ...
Control of volume status is a pivotal issue in haemodialysis therapy. Objective and practical management for maintaining normovolemia is needed. The investigators hypothesized that interv...
This is a non-randomized, open label, uncontrolled first in human safety study, testing the the material used in the artificial kidney device in subjects already on hemodialysis. Six subj...
Intradialytic systolic blood pressure (SBP) changes are related to the volume status; however, whether SBP change impacts on adverse outcomes depends on the volume status remains uncertain. We retrosp...
We derived a novel equation for calculating weekly urea standard Kt/V (stdKt/V) during hemodialysis (HD) based on urea mass removed, comparable to the approach during peritoneal dialysis.
Several clinical practice guidelines recommend regular assessment of physical activity and physical function as part of routine care in hemodialysis patients. However, there is no clear evidence to su...
Valuable information about cardiovascular system can be derived from the shape of aortic pulse wave being the result of reciprocal interaction between heart and vasculature. Pressure profiles in ascen...
For diabetes patients without nephropathy, glycemic control is important to reduce the risk or delay the progression of diabetes complications, including nephropathy. In diabetes patients on hemodialy...
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.
The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight.
The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
