Dialyzer membrane reaction
WebDialyzer reactions are long-appreciated complications of dialysis. Despite advances in dialysis machines and membranes, these life-threatening reactions st ill occur. It is imperative to recognize potential dia-lyzer reactions when assessing adverse dialysis events as reexposure to dialytic treatments could be WebThe first cellulosic membranes, Cuprophan type, were capable of activating the complement and causing hypoxia by leukocyte pulmonary sequestration [1] [7] [8] [9]. These membranes have evolved to asymmetric cellulose triacetate (ATA), with this complication disappearing [10]. The combined use of AN69 and ACEI membranes led to adverse …
