[Initial personal results of a technic of removing leukocytes by filtration on cotton fibers (Imugard Ig 500, Terumo)]. / Premiers résultats personnels d'une technique de déleucocytation par filtration sur fibres de coton (ImugardR IG 500, TerumoR).

ABSTRACT

The technical parameters of blood filtration through cotton Imugard IG 500 filters were evaluated. Sixty units of red cell concentrates were filtered. The mean value of the residual leukocytes indicated a leukocyte depletion greater than 98%, disregarding the unit age and the filtration temperature. The number of residual leukocytes was below 1 X 10(8) in 94% of the filtered units and less than 0.3 X 10(8) in 68%. The number of residual platelets was less than 1 X 10(10) in 92% of these units.
