Clotting With Different Dialyzer Membranes

Completed

• Conditions: Kidney Failure

• Registration Number: NCT02546037
• Lead Sponsor: University College, London

Brief Summary

Primary Objective:

The purpose of this study is to measure the amount of convection achieved with two different haemodiafilters designed for haemodiafiltration and clotting during haemodiafiltration treatment.

Detailed Description

This is a prospective observational cohort pilot study of patients under the care of the Royal Free Hospital with chronic kidney disease who have been established on regular thrice weekly haemodiafiltration treatments in a dialysis centre. Information on the study will be disseminated to the Royal Free consultant nephrologists at the dialysis centre with primary responsibility for the individual patient.
