INTRODUCTION Achieving normohydration remains a non-trivial issue in haemodialysis therapy. Preventing the deleterious effects of fluid overload and dehydration is difficult to achieve. Objective and clinically applicable methods for the determination of a target representing normohydration are needed. METHODS Whole-body bioimpedance spectroscopy (50 frequencies, 5-1,000 kHz) in combination w...
BACKGROUND Respiratory system disorders are one of the most prevalent complications in end-stage renal disease patients on hemodialysis. However, the pathogenesis of impaired pulmonary functions has not been completely elucidated in these patients. We designed a study to investigate acute effects of hemodialysis treatment on spirometry parameters, focusing on the relationship between pulmonary ...
BACKGROUND Data generated with the body composition monitor (BCM, Fresenius) show, based on bioimpedance technology, that chronic fluid overload in hemodialysis patients is associated with poor survival. However, removing excess fluid by lowering dry weight can be accompanied by intradialytic and postdialytic complications. Here, we aim at testing the hypothesis that, in comparison to conventio...
of the Main Paper In a recent paper we considered two networked service systems, each having its own customers and designated service pool with many agents, where all agents are able to serve the other customers, although they may do so inefficiently. Usually we want the agents to serve only their own customers, but we want an automatic control that activates serving some of the other customers...
Assessment of volume and hydration status is far from easy and therefore technology such as bioelectrical impedance vector analysis (BIVA) may complement our examination techniques. This study highlights the fact that clinical assessment of volume balance and BIVA may correlate, but whether the routine use of BIVA will avoid significant volume overload in the critically ill remains unknown. Fur...
Since the earliest days of hemodialysis, dietary sodium restriction has been recommended as a therapeutic means to mitigate problems of extracellular volume overload, hypertension and inter-dialytic weight gain. Recently, there has been a proliferation of human subjects' research examining the potential effects of dietary sodium curtailment. Herein we examine the available evidence with respect...
Endothelial glycocalyx degradation induced by fluid overload adds to the concern of a detrimental effect of uncontrolled fluid resuscitation and the risk of unnecessary fluid infusion. As a consequence, the use of new tools for monitoring response to fluids appears promising. From that perspective, the monitoring of plasma concentration of glycocalyx degradation markers could be useful.
The purpose of this investigation was to determine whether the increase in plasma volume (PV) frequently observed 24 hours after exercise is proportional to the magnitude of dehydration occurring during exercise. Seven males (age 21.6 ± 4.4 y, body mass 71.5 ± 8.5 kg; VO2peak 43 ± 7 mL·kg·minute(-1), peak 60-second cycling power output 282 ± 16 W) completed three cycling sessions at 50% of peak...
Perioperative fluid therapy remains the subject of active controversy. Indeed, clinical trials investigating the effects of fluid administration on outcome in surgical patients report controversial results. Critical review of these trials reveals that current standard fluid therapy is not at all evidence-based. Although it is evident that fluid overload should be avoided, replacement of fluid l...
