Effect of haemodialysis on regional and transmural inhomogeneities of the ventricular repolarisation phase.

Recent studies have indicated increased ventricular repolarisation dispersion in haemodialysis (HD) patients. The purpose of this study was to estimate the effect of the HD process on parameters of regional and transmyocardial repolarisation inhomogeneities. Thirty-two selected HD patients (without relevant diseases and medication known to affect the QT interval) were included.

Comparison of prescribed and delivered doses of dialysis using anthropometrically and bioelectrically measured patient volumes.

Background: One of the uncertainties in the prescription of dialysis dose, measured as Kt/V for urea (Kt/Vu), is the volume of urea distribution (V). The aim of our study was to compare two different approaches to estimating V and Kt/V, respectively, and to compare the predicted (prescribed) dose with the actually delivered dose, measured by urea kinetics.

Material/methods: V was estimated using anthropometric measures with the Watson formula (VWatson), and also by multi-frequency bioimpedance analysis (VBIS).

Care provided for hemodialysis patients in selected dialysis centres of the Lublin region.

The aim of the study was to answer the questions about the quality of dialysis for the patients treated in the selected dialysis centres of the Lublin region in relation to a quantitative and qualitative breakthrough observed in the field of Polish dialysis therapy in recent years. The study including 288 patients in 7 medium-sized centres used the questionnaire filled in by interviewers. The present paper analyses the patients' answers to the questions about medical care provided in a particular centre.

How are hemodialysis patients treated in the Lublin region--based on the selected issues of diagnosis and therapy.

The aim of the paper was to answer the questions about the quality of life of dialysis patients treated in the selected dialysis centres of the Lublin region in relation to the recent quantitative and qualitative breakthrough in dialysis therapy in Poland. The studies including 288 patients of 7 medium-sized centres were performed using the questionnaires filled in by interviewers. The present paper describes the results of analysis of the questions addressed to the centre staff but concerning the way of treatment of a particular patient.

Nutrition and hydration status improve with exercise training using stationary cycling during hemodialysis (HD) in patients with end-stage renal disease (ESRD).

Patients with end-stage renal disease (ESRD) undergoing hemodialysis and peritoneal dialysis are functionally limited as a consequence of their physical, emotional, and social problems. Exercise intolerance is a major problem in chronic renal failure. Stationary cycle training during hemodialysis is recommended as safe, effective, and practical in ESRD patients treated on hemodialysis.

Changes of extracellular volumes measured by whole and segmental bioimpedance analysis during hemodialysis in end-stage renal disease (ESRD) patients.

The bioimpedance technique is postulated as not expensive and non-invasive method for measurement of body water compartments in humans. However, the accuracy of the whole body bioimpedance technique has been questioned by several authors because of nonhomogenic nature of the human body. In the present study we used the whole body bioimpedance technique in comparison to segmental measurement from the arm and leg for assessment of extracellular water compartment.

Effect of acetate and bicarbonate dialysate on whole body bioimpedance (BIS) and segmental (thoracic) bioimpedance in hemodialysed (HD) patients.

There are sparse data about the influence of dialysis itself on bioimpedance measurement. The aim of this study was to evaluate the influence of dialysis without ultrafiltration on bioimpedance of thorax and bioimpedance of the whole body in hemodialysed patients. Isovolemic HD was performed during the first hour of dialysis session, using bicarbonate and then acetate dialysate.
