What is a bone marrow puncture needle

Bone marrow puncture needle is one of the commonly used diagnostic methods for hematological diseases, such as diseases of the blood system, iron deficiency anemia, hemolytic anemia, acute leukemia, chronic leukemia, aplastic anemia, multiple myeloma, etc., most of which are diagnosed by bone marrow puncture. If it is found that the white blood cells, hemoglobin and platelets in the blood routine are abnormal, bone marrow aspiration is generally required to identify the cause of the abnormal white blood cells, red blood cells and platelets. Bone marrow puncture is generally performed by injecting anesthetic locally into the anterior superior iliac spine and posterior superior iliac spine, and extracting marrow fluid with a bone marrow puncture needle for testing. Under normal circumstances, after puncture, as long as there is no local bleeding, you can move, which does not affect life or work. Myelocentesis is relatively simple, but it is usually necessary to check the clotting time before bone marrow puncture, and special attention should be paid to those with bleeding tendency, but hemophiliac patients should not do bone marrow puncture.
