Bone Marrow Acupuncture Needle For Extraction Of Bone Marrow Puncture Site

Bone marrow puncture is usually performed at the posterior superior iliac spine or anterior superior iliac spine of the pelvis. This site has clear bony landmarks and no major blood vessels and nerve trunks around, so it is safe. If multiple punctures are unsatisfactory, sternal puncture is optional in a few cases, as long as the oblique needle (30° to 45° to the sternum) is performed without penetrating the sternum, it is also safer. Before the puncture, local anesthesia should be applied at the puncture point. The anesthetics go from the skin, subcutaneously, and directly to the periosteum on the surface of the bone, so the puncture will not bring pain to the patient. A skilled operator can usually complete it in more than 10 minutes, so there is no need to worry. The puncture site should not be cleaned (including bathing) for 2 to 3 days after the sterile dressing is applied locally to avoid local infection.
