Clinical study of heparin-free hemodialysis with the inside of hollow fibers in dialyzer coated by human albumins

Abstract

Background/Objective: To investigate the therapeutics of heparin-free hemodialysis (HD) with the inside of hollow fibers in a dialyzer coated with human albumins (HFHd-A1). Methods: Clinical contrast study between HFHd-A1 and heparin-free HD with hollow fibers in dialyzer by normal saline flush (HFHd-NS) was performed by adopting the cross-over design method. The dialysis effect, the effect on life signs, blood platelet functions, change of dialyzer fiber-bundle volume, appearance image, and image of scanning electron microscopy of the inside of hollow fibers in dialyzer after dialysis and the biocompatibility of dialyzer of two HD methods were compared. Results: HFHd-A1 could overcome all shortcomings of HFHd-NS and had more merits and increased expenses for HFHd-A1 were not high. Conclusion: HFHd-A1 was an effective and feasible method which could salvage patients with bleeding diseases or bleeding tendency and who need HD. Copyright © 2002 S. Karger AG, Basel.
