BACKGROUND Uremic pruritus is a common and intractable symptom in patients on chronic hemodialysis, but factors associated with the severity of pruritus remain unclear. This study aimed to explore the associations of metabolic factors and dialysis adequacy with the aggravation of pruritus. METHODS We conducted a 5-year prospective cohort study on patients with maintenance hemodialysis. A visu...
background the presence of arterio-venous (a-v) fistula recirculation among hemodialysis (hd) patients markedly decrease adequacy of dialysis. objectives the present article summarize some of observations about clinical significance, causes, the most common techniques for measurement, and main source of pitfall in calculation of access recirculation. materials and methods a variety of literatur...
Since it was introduced in 1976, continuous ambulatory peritoneal dialysis (CAPD) has won acceptance in many centres and it is now regarded as an important alternative to haemodialysis. CAPD patients have comparable and, in some circumstances, better survival than those on chronic haemodialysis. It is indicated particularly in patients with diabetes mellitus, cardiovascular instability and at t...
Central venous catheter dysfunction is a frequent problem and often is defined as a blood flow <300 ml/min. This prospective, cross-sectional study included 259 patients and examined the relationship between catheter blood flow and dialysis adequacy as measured by urea reduction ratio (URR), single pool urea kinetics, and online effective ionic dialysance clearance. Dialysis adequacy at blood f...
Vascular accesses consist of permanent arteriovenous (AV) accesses (autogenous fistulas and synthetic grafts) and venous accesses (central venous catheters [CVCs]). AV accesses have fewer complications than venous accesses, and are therefore the preferred hemodialysis access. An important additional issue is whether the type of access influences adequacy of dialysis (i.e. Kt/V). Key limiting fa...
The need to improve haemodialysis (HD) therapies and to reduce cardiovascular and all-cause mortality frequently encountered by dialysis patients has been recognized and addressed for many years. A number of approaches, including increasing the frequency versus duration of treatment, have been proposed and debated in terms of their clinical efficacy and economic feasibility. Future prescription...
