4 cze 2024 · In this systematic review of nine studies and meta-analysis of four studies involving 576 adult patients with kidney failure receiving maintenance HD, we found that increasing dialysate flow rates from 500 ml/min to 800 ml/min improved dialysis adequacy as measured by URR (3.38) and spKt/V (0.08).
29 kwi 2024 · Blood flow rate (BFR) is a key determinant of dialysis adequacy under the condition of three times per week for 4 h for each hemodialysis (HD) session [Citation 1]. An increased BFR can significantly improve single-pool Kt/V (spKt/V) and may improve survival in maintenance hemodialysis (MHD) patients [Citation 2, Citation 3].
In dialysis practice, in HD, clearance is determined from what was removed from the blood, whereas in peritoneal dialysis (PD), clearance is determined by what is acquired in the dialysate. Instantaneous blood clearance in HD is extraction ratio multiplied by Qb (Fig 2 A). In clinical practice, we measure blood urea before and after HD.
17 paź 2019 · We recommend a blood flow rate of 5-7ml/kg/min for the majority of patients, using consumables appropriate to body size, with extracorporeal volume less than 10% of the patient’s blood volume. [1C] Rationale
20 kwi 2023 · Haemodialysis is the term used to describe a process in which blood is filtered across a semipermeable membrane, in a dialyser, causing toxins and excess fluid to be removed. Haemodialysis uses mechanical means to exploit two basic principles of biology and physics, namely diffusion and ultrafiltration, although the process of dialysis is in ...
1 sty 2020 · Hemodialysis with a dialysate flow rate of 700 mL/min should be considered in selected patients not achieving adequacy despite extended treatment times and optimized blood flow rate.
1 lut 2016 · This chapter covers all aspects of haemodialysis from equipment, technical details, dialysates, and dialysis access from fistulas to lines and their complications and management; complications of dialysis ranging from hypotension to dialyser reactions, measuring dialysis adequacy, anticoagulation, prescriptions of chronic dialysis, and dry weight.
