  • Title: The technique of therapeutic apheresis. Removal of abnormal blood elements may succeed when all else fails.
    Author: McLeod BC.
    Journal: J Crit Illn; 1991 May; 6(5):487-95. PubMed ID: 10147917.
    Abstract:
    Therapeutic apheresis is a generic term that refers to removal of abnormal blood cells and plasma constituents. The terms "plasmapheresis," "leukapheresis," and "erythrocytapheresis" describe the specific blood element that is removed. Apheresis therapies can be performed in the ICU to manage a number of neurologic, hematologic, and autoimmune disorders, including myasthenia gravis, Guillain-Barré syndrome, sickle-cell disease, and Goodpasture's syndrome. Apheresis procedures generally require two points of contact with the circulation--one for blood withdrawal and one for return; the withdrawal site should sustain a flow rate of at least 50 mL/min. Although apheresis is generally quite safe, hemodynamic instability, hypocalcemia, and dilutional coagulopathy can occur.
