Abstract:
A rotating filter system was evaluated for therapeutic plasma exchange. In vitro and in vivo studies revealed sieving coefficients of clinically important molecules to be essentially 1, with no substantial decline over time. A modification of the tubing system allowed for continuous flow, double access operation. Placing the collection bag at the base of the machine provided excellent plasma removal rates with only minimal blood flows. A rotating filter can provide a highly efficient system for therapeutic plasma exchange.
