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 · This retrospective study included 175 patients undergoing MHD treatment between July 2015 and March 2022, divided into two groups based on time-averaged effective blood flow rate (eBFR) median value.
1 kwi 2017 · During hemodialysis, intravascular fluid is removed directly and counterbalanced by refilling from the interstitial fluid compartment; the rapidly contracted circulating blood volume that occurs when the fluid removal rate is greater than the plasma refilling rate can be counter-productive.
Patients bearing a high-flow rate AV access and having a greater increase in left ventricular end diastolic volume (LVEDV) are clearly more likely to develop heart failure (HF). 4 A strong relationship exists between blood flow rate (Qa) and CO; furthermore, AV access contributes to the LVH.
15 sie 2022 · According to data from the US Renal Data System, daily HHD (n=3480) was associated with lower hazard of cardiovascular hospitalization (HR, 0.89 [95% CI, 0.86–0.93]) but a higher rate of infectious hospitalization (HR, 1.18 [95% CI, 1.13–1.23]) compared with a matched in-center hemodialysis population (n=17 400). 64 The FHN trials also ...
To support such high flow demands and avoid vascular collapse and thrombosis during hemodialysis treatments, the vascular access should be able to support blood flows of 0.6 to 1.2 L/min.
1 wrz 2015 · If blood pressure (BP) falls during haemodialysis (HD) [intradialytic hypotension (IDH)] a common clinical practice is to reduce the extracorporeal blood flow rate (EBFR). Consequently the efficacy of the HD (Kt/V) is reduced. However, only very limited knowledge on the effect of reducing EBFR on BP exists and data are conflicting.
