Does bone marrow puncture needle have side effect

Bone marrow aspiration has no side effects. The sites of bone penetration are usually iliac crest and sternum. There are no organs, blood vessels and nerves here, which is a safe place. Most of the bones in the body are "hollow", which are full of bone marrow. Even if the bones like the skull and ribs are "solid" on the surface, there is loose bone marrow in the middle. Bone piercing is a diagnostic procedure in which a needle is inserted into the bone marrow cavity and a small amount of bone marrow is extracted for testing. Some patients mistakenly believe that the marrow fluid extracted by bone marrow aspiration will damage the essence and vitality of the human body, so they are not willing to carry out the examination. In fact, the marrow fluid required by bone marrow aspiration is very small, generally about 0.1ml, while the total amount of normal bone marrow fluid in the human body is about 260ml. It can be seen that the marrow fluid extracted during bone marrow aspiration examination is insignificant compared with the total amount of the human body. In addition, the body is constantly regenerating a large number of cells every day. In addition, patients often think that bone marrow aspiration is painful and scary, which is unnecessary. The most common site of choice for "bone penetration" is the iliac crest, which is located on the lower lateral side of the abdomen, the lateral anterior projection of the lower abdomen. This procedure is usually done under local anesthesia and does not damage large nerves or blood vessels, so it does not cause excessive bleeding or neuromuscular paralysis.
