Prolonged dialyzer reuse.

Abstract

Clearance of urea, creatinine, phosphate and B12 in dialyzers reused up to 30 times were unchanged from the initial values. Residual formalin values were within acceptable levels and in several thousand dialyses no untoward reactions of any sort attributable to reuse were encountered. Neutropenia was constantly present with dialyzers prepared by automated reuse.
