Does a bone marrow aspiration needle hurt? Will there be adverse effects?

puncture site selection

① Anterior superior iliac spine: The puncture point is usually 1 to 2 cm behind and above the anterior superior iliac spine, where the bone surface is flat, easy to fix, and the operation is convenient and safe; ② Anterior and posterior superior spine: located on both sides of the sacral vertebra and above the buttocks (3) Manubrium: This place is rich in bone marrow. When the puncture in the above-mentioned parts fails, the manubrium can be punctured, but the bone here is thin, and there are atria and large blood vessels behind it, so the danger of penetration is strictly prevented. Use less; ④ Spinous process of lumbar vertebra: It is located at the prominence of spinous process of lumbar vertebra and is rarely used.

1. After the puncture needle enters the bone, avoid swinging too much to avoid breaking.

2. The puncture of the manubrium should not be inserted vertically, and excessive force should not be used to prevent penetration of the medial bone plate.

3. When aspirating bone marrow fluid, gradually increase the negative pressure. When doing cytomorphological examination, the suction volume should not be too much, otherwise the bone marrow fluid will be diluted, but it should not be too small.

4. The smear should be smeared immediately after the extraction of bone marrow fluid.

5. Bone marrow biopsy should be performed when multiple dry aspirations are performed.
