Abstract
A method for aspirating bone marrow includes the step of injecting anticoagulant into the area Of the bone marrow cavity surrounding the entry site of the aspiration needle. The amount of anticoagulant may be relatively small because the primary objective is to address the damage caused by entry of the needle into and through regions of the bone marrow cavity. As little as 0.5 ml heparin is injected prior to aspiration. Additional anticoagulant is provided in the collection syringe to facilitate further processing, as by centrifugal fractionation of the marrow to obtain desired components.
