bone marrow other cells

Other bone marrow cells are a type of bone marrow cytology. Bone marrow cytology is the most valuable for diagnosing hematopoietic diseases. It is also useful for diagnosing other non-hematopoietic diseases and for hepatosplenomegaly with unexplained fever, cachexia and unexplained causes. Diagnostic significance. Basic Information Specialist classification: cardiovascular examination classification: microscopy Applicable gender: whether men and women apply fasting: not fasting Tips: Preoperative patients should follow the doctor's instructions to position themselves. Normal value Reticulocytes 0 to 0.01 (0 to 1%). Endothelial cells 0 to 0.014 (0 to 1.4%). Megakaryocytes range from 0 to 0.003 (0 to 0.3%). Phagocytic cells 0 to 0.004 (0 to 0.4%). Tissue basophils 0 to 0.005 (0 to 0.5%). Tissue eosinophils 0 to 0.002 (0 to 0.2%). Fat cells 0 to 0.001 (0 to 0.1%). Unknown cells 0 to 0.001 (0 to 0.1%). Clinical significance Abnormal results: acute and chronic aplastic anemia and radiation sickness, reticular cells, plasma cells, tissue basophils. Malignant reticular cell disease shows an increase in reticular cells and abnormal morphology. Some infections (black fever) see reticular cells. High results may be diseases: aplastic anemia, pediatric Gaucher disease considerations Preoperative preparation: The patient is placed in accordance with the doctor's instructions. Inspection process Inspection method: bone marrow examination. Inspection process: 1. Select the puncture site. 2. Anesthesia. 3. Fix the length of the needle. 4. The doctor's left thumb and finger are fixed at the puncture site. The right hand-held bone marrow puncture needle is inserted perpendicularly to the bone surface. If the sternum is puncture, it should be inserted at an angle of 30o to 40o with the bone surface. When the needle tip touches the bone, rotate the needle along the long axis of the needle of the needle and push it forward to slowly penetrate the bone. 5. Extract the bone marrow fluid and pull out the needle core, connect the dry syringe (10m1 or 201m1), and use the appropriate force to extract the bone marrow fluid. Bone marrow cytology check steps: 1. Smear: It is required that the smear slide and push piece should be clean, no putty pollution, the smear should be thin and uniform, the number of smears is about 10, and two blood samples are used for comparison. 2. Dyeing: commonly used Wright-Gemsa mixed staining; cytochemical staining is often used together. 3. Low magnification examination: to determine the degree of bone marrow hyperplasia, usually the ratio of mature red blood cells to nucleated cells in bone marrow slices to determine the bone marrow hyperplasia 4. Oil Mirror Inspection: Select the cells to be evenly distributed. Under the oil microscope, classify and count at least 200 nucleated cells, and pay attention to whether there is qualitative change. Not suitable for the crowd Hemophilia and disseminated intravascular coagulation, if there is no special need, do not do bone marrow puncture. Adverse reactions and risks There may be bleeding and infection.
