Erratum: Relationship between the filter type and blood flow rate and, dialysis adequacy in hemodialysis patients

We studied the effect of extracorporeal blood flow rate (BFR) on access recirculation (recirc) in 19 hemodialysis patients. BUN was determined in simultaneous peripheral (P), arterial (A), and venous (V) blood obtained at BFRs of 200, 400 and 600 ml/min. Percent recirc was calculated for each BFR using the formula (P-A) / (P-V) X 100. Venous drip-chamber (VP) and pre-blood-pump (AP) pressures were measured at each BFR. Fistulograms were performed in 10 patients, and stenoses were identified in 5, all at the proximal (arterial) end of the access. Recirc increased with increasing BFR from 200 to 400 ml/min but increased little from 400 to 600 ml/min. At all BFRs recirc in the stenotic patients was higher than that of non-stenotic or unstudied patients. Urea clearance, corrected for recirc, rose with blood flow both in stenotic and non-stenotic patients. There were no differences in AP or in VP between stenotic and non-stenotic patients. At BFR ≥ 400 ml/min, a recirc threshold of 15% identified stenoses with sensitivity 100% and specificity 71%. We conclude (1) recirc increases with increasing BFR but not enough to outweight the concomitant increase in urea clearance; (2) significant access stenosis and recirc may be present even with low VP; (3) recirc was associated with arterial side stenoses; (4) at BFR ≥ 400 ml/min, access stenosis is associated with recirc > 15%.

The Impact

Abstract Background: The objective of this work was to assess the impact of the decrease in dialysate flow rate on the dialysis dose delivered (spKt /V) to chronic hemodialysis patients and to estimate the resulting water saving. Methods: It was a prospective 4-week-period study that included chronic hemodialysis patients with clinical and hemodynamic stability. The patients successively underwent hemodialysis with a dialysate flow rate of 500 ml / min, at 1, 1.2 and 1.5 times the blood flow rate. Each dialysate flow rate was applied for one week. During these 4 weeks, the following parameters were kept constant: duration of dialysis, blood flow rate, anticoagulation, membrane nature and surface. Results: Forty-five chronic hemodialysis patients were included with a mean age of 48.4 ± 12.07 years. The weekly average spKt/V was statistically higher with a dialysate flow rate at 1.5 times the blood flow rate compared to the dialysate flow at 500 mL / min (p = 0.001). The proportion of patients achieving a standardized dialysis dose ≥ 1.4 was statistically higher with dialysate flow at 500 mL / min (64.4%) compared to dialysate flow at 1 or 1.2 times the blood flow rate which were 57.8% and 55.6%, respectively. It was statistically higher with a dialysate flow at 1.5 times the blood flow (93.3%) compared to the dialysate flow at 500 mL / min (p = 0.036). The dialysate volume used with a dialysate flow rate of 500 mL / min was higher compared to the other dialysate flow rates (p = 0.0001). Conclusions: An adequate dialysis dose could be achieved with a dialysate flow rate of 1.5 times the blood flow rate, thereby saving significant amount of water.

Abstract: Objective: To ensure that the patientâ€™s treatmentÂ and control of the patientâ€™s blood in the course of long-termÂ dialysis, in order to ensure the blood flow rate at the rate of hemodialysis in the blood vessel of hemodialysis patients, mortality rate.Â Methods: In many Western countries, it has beenÂ found from the experience of long-term accumulation, arteriovenous fistula (AVF) is the first choice for long-term dialysisÂ blood patients, which has a lot of a little bit, not only from theÂ infection rateÂ and blood flow, which has a lot of advantages.But its existence is also a lot of complications, non-thermalÂ Commscope irradiation is a very effective way. Results: TheÂ method was compared with the method, and it was found thatÂ P <0.05, which wasÂ statistically significant. Conclusion: AVFÂ is the preferred method of vascular access in patients with persistent dialysis, which is very easy to be punctured and has aÂ very long time for maintenance. It is very important to carryÂ out the treatment, treatmentÂ and surveillance of AVF complications and the use of means.
