bone marrow red blood cell system

The bone marrow erythrocyte system is 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: bone marrow examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Reduction: If the granulocyte and megakaryocytes are not reduced, they are found in pure red blood cell aplastic anemia, hemolytic anemia, and nutritional anemia. Normal value: Original red blood cells: 0-0.019 Early red blood cells: 0.002-0.026 Young and young red blood cells: 0.026-0.107 Late red blood cells: 0.052-0.175 Above normal: Increase: red blood disease, red blood leukemia (Di-Guglie-Lmo syndrome), myelodysplastic syndrome, etc., with primary red and early erythrocytosis. negative: Positive: Tips: Preoperative patients should follow the doctor's instructions to position themselves. Normal value The original red blood cells are 0 to 0.019 (0 to 1.9%). Early red blood cells are 0.002 to 0.026 (0.2% to 2.6%). The young and middle red blood cells are 0.026 to 0.107 (2.6% to 10.7%). Late red blood cells are 0.052 to 0.175 (5.2% to 17.5%). Clinical significance Abnormal result increase: 1 The original red and early erythrocytosis are mainly red blood disease, erythroleukemia (Di-Guglie-Lmo syndrome), and myelodysplastic syndrome. 2 The young and young erythrocytosis is mainly composed of various proliferative anemia (hemolytic anemia, acute hemorrhagic anemia, megaloblastic anemia), acute exacerbation of primary thrombocytopenic purpura, thalassemia, kala-azar, and the like. 3 with erythrocytosis as the main cause of iron deficiency anemia, chronic aplastic anemia. Reduction: If the granulocyte and megakaryocytes are not reduced, they are found in pure red blood cell aplastic anemia, hemolytic anemia, and nutritional anemia. Low results may be diseases: secondary iron granulocyte anemia, pediatric iron erythrocyte anemia, hemolytic anemia, pediatric pure red blood cell aplastic anemia, high nutritional anemia results may be diseases: anemia caused by excessive hemolysis Precautions 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 proliferation of bone marrow. 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 Can cause bleeding and infection.
