1.Why do patients with blood disorders need bone marrow aspiration?
Bone marrow aspiration is one of the important tests for hematologic diseases. Bone marrow is the main organ of hematopoiesis. Through bone marrow aspiration cytology examination, we can understand the production of various cells in the bone marrow, the morphology of various cells, changes in the composition and the discovery of abnormal cells, etc., in order to make a clear diagnosis, observe the efficacy and estimate prognosis.
Combining the bone marrow image, blood picture and clinical information, a definite diagnosis can be made or support the clinical diagnosis for some diseases. For example, various types of leukemia, multiple myeloma, and metabolic diseases. Propose a compatible diagnosis: e.g. calcium-iron anemia, aplastic anemia. The bone marrow image does have certain changes, which can always be used as a reference for further examination, although it cannot provide a supporting or negative opinion on the clinical presentation.
2.Does it hurt to have a bone marrow aspiration?
Bone marrow aspiration is performed under local anesthesia by inserting a puncture needle into the bone marrow cavity of the anterior or posterior superior iliac spine on the lateral side of the pelvis and extracting a small amount of bone marrow fluid for laboratory examination. These areas are generally free of major blood vessels and nerves, so they will not cause serious damage and will not have much impact on body sensation and activities.
3.What should I pay attention to after bone puncture?
After bone puncture, the puncture site should be covered with a sterile dressing, and the puncture site should be compressed for 5 to 10 minutes, and the puncture site should not be washed with water for 3 days after surgery to prevent infection. Pay attention to observe whether there is blood and ooze at the puncture site, and notify the nurse in time to change the dressing if blood and ooze are found.
