The stress a patient is subjected to during dialysis treatment can be reduced by using a synergetic approach by the medical team. The integration into therapy of the positive psychical resources such as: active positive coping mechanisms, individual or family mental resilience, improvement of the image and self-esteem, better tolerance to frustration can represent an important part in the impro...

Survival and quality of life of dialysis patients are strictly dependent on the quality of the haemodialysis (HD) treatment. In this respect, dialysate composition, including water purity, plays a crucial role. A major aim of HD is to normalize predialysis plasma electrolyte and mineral concentrations, while minimizing wide swings in the patient's intradialytic plasma concentrations. Adequate s...

Go slow" dialysis is a gentle, intermittent hemodialysis therapy for acute renal failure patients, with advantages compared to slow, continuous therapies. It employs a recirculating closed dialysate circuit. A two-pool urea kinetic model is elaborated to determine kinetic parameters from blood and dialysate concentrations. This will allow quantification of the therapy. Variable clearance is inc...

Serial nerve conduction velocities in the peroneal and ulnar nerves have been measured in 10 patients on regular dialysis treatment over a three year period. Each patient alternated between phases on dialysis with magnesium-containing dialysate (1·5-1·7 m-equiv/l.) and phases on `magnesium-free' dialysate (0·2 m-equiv/l.). Plasma magnesium concentrations were high both pre- and post-dialysis du...

The aim of this work was to evaluate the contributions of the main chromophores to the total UV absorbance of the spent dialysate and to assess removal dynamics of these solutes during optical on-line dialysis dose monitoring. High performance chromatography was used to separate and quantify UV-absorbing solutes in the spent dialysate sampled at the start and at the end of dialysis sessions. Ch...

Peritoneal dialysis (PD) is a well established renal replacement therapy (RRT). It appears to have some excellent properties as a first line RRT, as it preserves residual renal function, improves clearance of middle and larger solutes and preserves vascular access. To improve PD penetration, it is necessary to have a well established pre-dialysis programme, as information seems to be the clue i...

Anaemia secondary to chronic kidney disease is a complex syndrome. Adequate dialysis can contribute to its correction by removing small, and possibly middle/large molecules, that may inhibit erythropoiesis. A clear relationship between higher haemoglobin or haematocrit levels, lower recombinant human erythropoietin (epoetin) dose and increase in dialysis dose has been reported in a number of pr...

The debate on the most adequate dialysate calcium concentration for intermittent haemodialysis therapy is ongoing. There is probably no one optimal concentration. In general, one would like to maintain a neutral calcium balance in adult haemodialysis patients. However, a slightly negative balance may be preferable to avoid soft-tissue calcium accumulation in face of net calcium loss from the bo...

BACKGROUND The Sodium Lowering in Dialysate (SoLID) trial is an ongoing a multi-center, prospective, randomised, single-blind (assessor), controlled, parallel assignment clinical trial, enrolling 96 home and self-care hemodialysis (HD) patients from 7 centers in New Zealand. The trial will evaluate the hypothesis that lower dialysate [Na+] during HD results in lower left ventricular (LV) mass. ...
