Most Common Risks of Bone Marrow Aspirate

The most common risks of bone marrow aspirate are bleeding, infection, damage to the cutaneous nerve, and heart damage during sternal puncture.

1. Bleeding:

If the patient's thrombocytopenia or coagulation dysfunction during the bone marrow puncture, and the bleeding is not well compressed after the bone marrow puncture, there may be persistent bleeding after the operation. Patients who tend to undergo bone marrow puncture require a longer period of compression to stop bleeding.

2. Infection:

Due to lack of attention to aseptic operation during bone marrow puncture, infection at the puncture site can occur. In severe cases, bacteria may invade the blood and even bone marrow through the puncture site, causing sepsis or osteomyelitis.

3. Cutaneous nerve damage:

There are many cutaneous nerve distributions in the puncture area. During the puncture, the cutaneous nerve may be damaged, which may cause local paresthesia of small patches of skin.

4. Heart damage during sternal puncture:

During sternal puncture, there is a fatal risk of injuring the blood vessels or the heart behind the sternum due to the forceful penetration of the sternum plate.
