title: Sorbent membranes used in a conventional dialyzer format. In vitro and clinical evaluation.
abstract: The possibility of installing sorbent membranes into proven dialyzer configurations could result in certain advantages over dialyzers with conventional membranes. A sorbent membrane dialyzer might prove superior in that it allows a higher clearance in the middle molecule molecular weight range, thereby shortening dialysis time and possibly allowing a reduction in the amount of dialysate fluid required. Finally, this device could be used without dialysate if the technician's goal is to eliminate a single substance readily adsorbed by charcoal. For example, this would apply to the treatment of certain intoxications. In vitro data were established for six substances in the molecular weight range of 60 to 5200 daltons and compared to corresponding results for conventional Cuprophan dialyzers. Clinical evaluation of sorbent membrane dialyzers for patients with uremia and intoxication, both with and without use of dialysate, has proven effective with no adverse reactions.
