Platelet transfusion and catheter insertion for plasma exchange in patients with thrombotic thrombocytopenic purpura and a low platelet count

Abstract

We propose a practical algorithm to avoid unnecessary PLT transfusion before CVC insertion for rapid PE in the initial management of TTP patients. We recommend no prophylactic PLT transfusion but CVC insertion in a compressible vein under ultrasound guidance by an experienced team or quick PE started on two peripheral veins if possible. PLTs should only be transfused in case of severe bleeding in association with plasma infusion and CVC insertion for immediate PE.
