What should I know about the bone marrow aspirate?

Patients often confuse a bone marrow aspirate with a more involved and more painful bone marrow biopsy.

We only perform the less involved and much more comfortable bone marrow aspirate. This is a short (20 to 40 minute) in office procedure where the skin and tissues are numbed and a needle is used to withdraw marrow blood, which contains the stem cells. One site on each will be numbed and three samples are taken from each site. Because the area is extensively numbed, 88% of our patients report that the procedure is very comfortable and would do it again.

To better access how our patients feel about this procedure, we ran questionnaires on 44 consecutive patients undergoing marrow draws (primarily in Jan-Feb 2009). 86% said they had no to mild discomfort. 88% said that the procedure was either less uncomfortable or about what they thought it would be. 88% also said they would do it again without hesitation.

A properly performed marrow aspirate procedure should not be uncomfortable to the vast majority of patients.
