Sorbent Hemodialysis: Clinical Experience With New Sorbent Cartridges and Hemodialyzers

Abstract

To recycle spent dialysate, a sorbent hemodialyzer uses a purification cartridge, adapted from water reclamation systems originally designed for the aerospace program. Increasing interest in home hemodialysis has driven a renewed examination of sorbent dialyzer technology, resulting in the development of a modern sorbent hemodialyzer and an array of new sorbent cartridges. Initial clinical experience with the Allient Hemodialysis System and the new sorbent cartridges is presented, with an emphasis on achievable clearances and ultrafiltration, as well as information about symptom profile and electrolyte balance.
