What is the hazard of taking bone marrow?

Aspiration of bone marrow with a puncture needle is generally harmless. Bone marrow is a hematopoietic tissue and generally has the ability to self-renew. If necessary, a small amount of bone marrow fluid will be drawn without much impact on the body. Moreover, this operation helps to clarify the diagnosis of certain blood system diseases, which is beneficial to the metabolism of body cells and bone marrow to a certain extent; and the location of bone marrow extraction is close to the body surface, which is relatively easy to obtain materials. There are no important internal organs near the posterior superior iliac spine. The blood vessels and nerves are relatively safe to operate. However, when extracting bone marrow, it is necessary to strictly grasp the indications and contraindications, pay attention to the principle of aseptic operation, and avoid the occurrence of infections.
