Does It Hurt To Have A Bone Marrow Piercing Needle? Will There Be Any Adverse Effects?

Selection of puncture site
① Anterior superior iliac spine: 1 ~ 2cm above the posterior of the anterior superior iliac spine is often taken as the puncture point, where the bone surface is relatively flat, easy to fix, convenient and safe operation; ② Anterior and posterior superior spines: located on both sides of the sacral vertebra, above the hip bone protrusion; ③ Manubrium sternum: The bone marrow content here is rich, when the above part of the puncture failed, can be used for manubrium sternum puncture, but the bone here is thin, there are atrium and large blood vessels behind, to prevent the risk of penetration, less selection; ④ Lumbar spinous process: located in the source of lumbar spinous protrusion, rarely used.
1. Avoid swinging the needle too much after entering the bone to avoid breaking.
2. Manubrium sternum puncture is not allowed to enter the needle vertically, and it is not allowed to exert too much force to avoid penetrating the medial bone plate.
3. When aspirating bone marrow fluid, gradually increase the negative pressure. When conducting cell morphology examination, the aspirating amount should not be too much, otherwise the bone marrow fluid will be diluted, but it should not be too little.
4. Smear immediately after marrow fluid extraction.
5. Bone marrow biopsy should be performed for multiple dry draws.
