Objective: Assessment of fluid status in chronic peritoneal dialysis (PD) patients is complex. Clinical evaluation based solely on body weight, blood pressure, volume of ultrafiltration (UF) and peripheral edema is insufficient. A non-invasive test, bioelectrical impedance analysis (BIA) might be of potential benefit. Aim: To test whether BIA correlates with other ancillary markers of extracellular [...]

Fluid management is recognized as a basic component of management of patients on dialysis. Fluid overload is an important adverse factor in patient outcomes, and the negative effects of fluid depletion, including on residual renal function, are aIso increasingly being recognized. The complexities of fluid distribution in renal failure need to be understood to inform [...]

BACKGROUND AND OBJECTIVE. The level of dehydration has been known to be a predisposing factor for the development of decompression sickness in divers. The aim of this study was to determine the level of dehydration in divers who dove with heliox and to determine whether the source of this dehydration was intracellular and/or extracellular by [...]

Background: Patients admitted to surgery may be dehydrated, which is difficult to diagnose except when it is severe (>5% of the body weight). We hypothesized that modest dehydration can be detected by kinetic analysis of the blood hemoglobin concentration after a bolus infusion of crystalloid fluid.Methods:Four series of experiments were performed on 10 conscious, healthy [...]
