What is the bone marrow aspiration needle?

Bone marrow puncture is a relatively safe method for diagnosing blood system diseases. Take a little bone marrow fluid for examination. Like blood examination, there are basically no sequelae. It can check diseases such as blood system, such as iron deficiency anemia, hemolytic anemia, acute leukemia, chronic leukemia, aplastic anemia, etc. But bone marrow aspiration is different from venous blood collection and is one of the trauma tests. The specific method of bone marrow aspiration is to inject anesthesia into the anterior superior iliac spine and posterior superior iliac spine first. Then use a puncture needle to puncture, press for a period of time after puncture, and there is no bleeding. Generally, it will not affect life or work after surgery. Bone marrow aspiration is relatively simple, but the clotting time should be checked before aspiration, especially in patients with bleeding tendency, especially those with hemophilia, which are contraindicated. Therefore, in rare cases, bone marrow aspiration may lead to complications such as local bleeding, hematoma, and infection, but no sequelae will occur.
