[Performance of reused plasma separating filters].
The performances of reused plasma separators are studied with the coefficient of filtration of IgG and IgM through the membrane and the extraction of the same immunoglobulins from the patient's plasma. 10 filters are used for 32 plasma exchanges in 6 patients. At the second use, the filter retains 78% of the initial performances. There is no more loss of the performances with the next uses. Biologic efficiency appreciated by extraction of IgG don't decrease significantly with the reuses. Those findings let us suggest the reuse of the plasma separators.
