The impact of haemodialysis arteriovenous fistula on haemodynamic parameters of the cardiovascular system
BACKGROUND Satisfactory vascular access flow (Qa) of an arteriovenous fistula (AVF) is necessary for haemodialysis (HD) adequacy. The aim of the present study was to further our understanding of haemodynamic modifications of the cardiovascular system of HD patients associated with an AVF. The main objective was to calculate using real data in what way an AVF influences the load of the left vent...
متن کاملHaemodynamic consequences of changing potassium concentrations in haemodialysis fluids
BACKGROUND A rapid decrease of serum potassium concentrations during haemodialysis produces a significant increase in blood pressure parameters at the end of the session, even if effects on intra-dialysis pressure are not seen. Paradoxically, in animal models potassium is a vasodilator and decreases myocardial contractility. The purpose of this trial is to study the precise haemodynamic consequ...
متن کاملPredictors of haemodynamic instability and heart rate variability during haemodialysis.
BACKGROUND The pathogenesis of haemodialysis-induced hypotension is multifactorial and may include autonomic nervous system dysfunction. The present study was undertaken to (i) determine heart rate variability (HRV) in chronic haemodialysis patients without and with haemodynamic instability (hypotension-prone) during ultrafiltration and (ii) identify patients at risk and the predictors of dialy...
متن کاملHaemodynamic stability in standard bicarbonate haemodialysis and long-hour slow-flow bicarbonate haemodialysis.
BACKGROUND The interplay of correct solute mass balances, such as that of sodium (Na+) and potassium (K+) (respectively, Na+MB and K+MB) with adequate ultrafiltration volumes (V(UF)), is crucial in order to achieve haemodynamic stability during haemodialysis (HD). The GENIUS single-pass batch dialysis system (Fresenius Medical Care, Germany) consists of a closed dialysate tank of 90 L; it offer...
متن کاملNon-invasive evaluation of vessels by duplex sonography prior to construction of arteriovenous fistulas for haemodialysis.
PURPOSE The prospective study was aimed at estimating the value of duplex sonography for imaging arteries before arteriovenous fistula (AVF) construction and of evaluating the influence of this method on the outcome of fistula construction. METHODS A total of 35 patients with end stage renal disease were examined by duplex sonography (DS) before AVF construction, and 27 of them with patent AV...
