What Are The Bone Marrow Puncture Sites For Bone Marrow Puncture Needles?

The bone marrow puncture needle is often chosen from the posterior superior iliac spine or anterior superior iliac spine of the pelvis, where the bony markings are clear and there are no large blood vessels or nerve trunks around, so the safety is good. If multiple punctures are unsatisfactory, sternal puncture is optional in a few cases, which is also safer as long as the needle is inserted obliquely (at 30° to 45° to the sternum) and does not penetrate the sternum. Before puncture, local anesthesia is administered at the puncture site, and the anesthetic is administered from the skin, subcutaneously, and directly to the periosteum on the bone surface, so the puncture does not cause pain to the patient. It usually takes more than 10 minutes for a skilled operator to complete, so there is no need to have any concerns. It is not advisable to wash (including bathing) for 2 to 3 days after applying sterile dressing locally to the puncture site to avoid local infection.
