What is the optimum dialysate flow in post-dilution online haemodiafiltration?

Introduction: In post-dilution online haemodiafiltration (OL-HDF), the only recommendation concerning the dialysate, or dialysis fluid, refers to its purity. No study has yet determined whether using a high dialysate flow (Qd) is useful for increasing Kt or ultrafiltration-infusion volume. Objective...

520			\|a Introduction: In post-dilution online haemodiafiltration (OL-HDF), the only recommendation concerning the dialysate, or dialysis fluid, refers to its purity. No study has yet determined whether using a high dialysate flow (Qd) is useful for increasing Kt or ultrafiltration-infusion volume. Objective: Study the influence of Qd on Kt and on infusion volume in OL-HDF. Material and methods: This was a prospective crossover study. There were 37 patients to whom 6 sessions of OL-HDF were administered at 3 different Qds: 500, 600 and 700 mL/min. A 5008® monitor was used for the dialysis in 21 patients, while an AK-200® was used in 17. The dialysers used were: 20 with FX 800® and 17 with Polyflux-210®. The rest of the parameters were kept constant. Monitor data collected were effective blood flow, effective dialysis time, final Kt and infused volume. Results: We found that using a Qd of 600 or 700 mL/min increased Kt by 1.7% compared to using a Qd of 500 mL/min. Differences in infusion volume were not significant. Increasing Qd from 500 mL/min to 600 and 700 mL/min increased dialysate consumption by 20% and 40%, respectively. Conclusions: With the monitors and dialysers currently used in OL-HDF, a Qd higher than 500 mL/min is unhelpful for increasing the efficacy of Kt or infusion volume. Consequently, using a high Qd wastes water, a truly important resource both from the ecological and economic points of view.

No study has yet determined whether using a high dialysate flow (Qd) is useful for increasing Kt or ultrafiltration-infusion volume. Objective: Study the influence of Qd on Kt and on infusion volume in OL-HDF. Material and methods: This was a prospective crossover study. There were 37 patients to whom 6 sessions of OL-HDF were administered at 3 different Qds: 500, 600 and 700 mL/min. A 5008® monitor was used for the dialysis in 21 patients, while an AK-200® was used in 17. The dialysers used were: 20 with FX 800® and 17 with Polyflux-210®. The rest of the parameters were kept constant. Monitor data collected were effective blood flow, effective dialysis time, final Kt and infused volume. Results: We found that using a Qd of 600 or 700 mL/min increased Kt by 1.7% compared to using a Qd of 500 mL/min. Differences in infusion volume were not significant. Increasing Qd from 500 mL/min to 600 and 700 mL/min increased dialysate consumption by 20% and 40%, respectively. Conclusions: With the monitors and dialysers currently used in OL-HDF, a Qd higher than 500 mL/min is unhelpful for increasing the efficacy of Kt or infusion volume.

abstract	Introduction: In post-dilution online haemodiafiltration (OL-HDF), the only recommendation concerning the dialysate, or dialysis fluid, refers to its purity. No study has yet determined whether using a high dialysate flow (Qd) is useful for increasing Kt or ultrafiltration-infusion volume. Objective: Study the influence of Qd on Kt and on infusion volume in OL-HDF. Material and methods: This was a prospective crossover study. There were 37 patients to whom 6 sessions of OL-HDF were administered at 3 different Qds: 500, 600 and 700 mL/min. A 5008® monitor was used for the dialysis in 21 patients, while an AK-200® was used in 17. The dialysers used were: 20 with FX 800® and 17 with Polyflux-210®. The rest of the parameters were kept constant. Monitor data collected were effective blood flow, effective dialysis time, final Kt and infused volume. Results: We found that using a Qd of 600 or 700 mL/min increased Kt by 1.7% compared to using a Qd of 500 mL/min. Differences in infusion volume were not significant. Increasing Qd from 500 mL/min to 600 and 700 mL/min increased dialysate consumption by 20% and 40%, respectively. Conclusions: With the monitors and dialysers currently used in OL-HDF, a Qd higher than 500 mL/min is unhelpful for increasing the efficacy of Kt or infusion volume. Consequently, using a high Qd wastes water, a truly important resource both from the ecological and economic points of view.

Objective: Study the influence of Qd on Kt and on infusion volume in OL-HDF. Material and methods: This was a prospective crossover study. There were 37 patients to whom 6 sessions of OL-HDF were administered at 3 different Qds: 500, 600 and 700 mL/min. A 5008® monitor was used for the dialysis in 21 patients, while an AK-200® was used in 17. The dialysers used were: 20 with FX 800® and 17 with Polyflux-210®. The rest of the parameters were kept constant. Monitor data collected were effective blood flow, effective dialysis time, final Kt and infused volume. Results: We found that using a Qd of 600 or 700 mL/min increased Kt by 1.7% compared to using a Qd of 500 mL/min. Differences in infusion volume were not significant. Increasing Qd from 500 mL/min to 600 and 700 mL/min increased dialysate consumption by 20% and 40%, respectively. Conclusions: With the monitors and dialysers currently used in OL-HDF, a Qd higher than 500 mL/min is unhelpful for increasing the efficacy of Kt or infusion volume. Consequently, using a high Qd wastes water, a truly important resource both from the ecological and economic points of view.
abstract_unstemmed	Introduction: In post-dilution online haemodiafiltration (OL-HDF), the only recommendation concerning the dialysate, or dialysis fluid, refers to its purity. No study has yet determined whether using a high dialysate flow (Qd) is useful for increasing Kt or ultrafiltration-infusion volume. Objective: Study the influence of Qd on Kt and on infusion volume in OL-HDF. Material and methods: This was a prospective crossover study.
