Bone marrow abnormal cells and parasites

Abnormal bone marrow cells and parasites are a type of bone marrow cytology, and bone marrow cytology is most valuable for diagnosing hematopoietic diseases. The oil smear of the bone marrow smear was observed from the middle section, from the head to the tail, and the upper and lower squats gradually progressed, counting 200 to 500 nucleated cells. According to the morphological characteristics of the cells, they were identified one by one, and the presence or absence of parasites was observed. Basic Information Specialist classification: cardiovascular examination classification: microscopy Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Normal when negative. Positive: Abnormal cells Reed-Sternberg cells, Gaucher cells, Niemann-Pick cells, metastatic cancer cells, and the like. Tips: Preoperative patients should follow the doctor's instructions to position themselves. Normal value negative. Clinical significance (1) Abnormal cells Reed-Sternberg cells, Gaucher cells, Niemann-Pick cells, metastatic cancer cells, and the like. (2) Parasitic Plasmodium, Leishmania-Donouani'sbody (Lidu body, kala-azar). Positive results may be diseases: pediatric visceral larval migration, pediatric retinoblastoma, pediatric neuroblastoma 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 May cause bleeding and infection.
