Bone marrow puncture usually chooses the posterior superior iliac spine or the anterior superior iliac spine of the pelvis. The bony marks of this part are clear, and there are no large blood vessels and nerve trunks around, so it is safe. If you are not satisfied with multiple punctures, sternal puncture may be selected in a few cases. It is safer to perform an oblique needle (30 to 45 degrees to the sternum) without penetrating the sternum. Before the puncture, the puncture point must be locally anesthetized. The anaesthetic is applied from the skin and under the skin to the periosteum on the bone surface, so the puncture will not cause pain to the patient. Skilled operators usually can complete it in more than ten minutes, so there is no need to worry about it. The puncture point is not suitable for washing (including bathing) two to three days after applying a sterile dressing to avoid local infection.
