The three-pore model of peritoneal fluid transport predicts that once the osmotic gradient has dissipated, fluid reabsorption will be due to a combination of small-pore reabsorption driven by the intravascular oncotic pressure, and an underlying disappearance of fluid from the cavity by lymphatic drainage. Our study measured fluid transport by these(More)
OBJECTIVES To establish which clinical factors are associated with an increased proportion of extracellular fluid (ECF) in peritoneal dialysis (PD) patients. DESIGN A single-center, cross-sectional analysis of 68 stable PD patients. METHOD Bioelectrical impedance measurements (RJL, single frequency; RJL Systems, Clinton, Michigan, USA) of resistance and(More)
INTRODUCTION Mechanisms of water flow across the peritoneal membrane include diffusion, convection, and reabsorption. OBJECTIVES To understand these processes more clearly we have developed a method to measure transport of water across the peritoneal membrane. METHODS An artificial gradient of deuterated water (HDO) between blood and dialysate(More)
The three-pore model of peritoneal membrane physiology predicts sieving of small solutes as a result of the presence of a water-exclusive pathway. The purpose of this study was to measure the diffusive and convective components of small solute transport, including water, under differing convection. Triplicate studies were performed in eight stable(More)
In-center intermittent peritoneal dialysis (IPD) is classically an old peritoneal dialysis (PD) modality involving thrice-weekly therapy in a hospital or dialysis center setting (1,2). In the early days of PD in the 1970s, IPD was widely used, but it lost popularity because of concerns about insufficient small-solute clearances (3) and also because of(More)
