serous cavity effusion cell count

The cell count is to determine the number of cells in the effusion. Generally, the microscopic counting method and the sample dilution method are used. The direct counting method is suitable for the detection of effusion with clear appearance and small number of cells. The serosal cavity is also called the body cavity, including the pleural cavity, peritoneal cavity and pericardium cavity. The surface of the serosa is covered with mesothelial cells. There is a narrow serosa cavity between the visceral serosa and the parietal serosa. Liquid, which acts as a lubricant. In the pathological conditions such as tumor metastasis, inflammatory stimulation or circulatory disturbance, pleural effusion, ascites and pericardial effusion can be formed and effusion can be taken for cytological examination. Basic Information Specialist classification: Digestive examination classification: chest and ascites examination Applicable gender: whether men and women apply fasting: not fasting Tips: When you are checking, you should cooperate with your doctor to take the serous effusion. Normal value Normal people have no fluid. Clinical significance Abnormal result This test is used to identify leaks and exudates. The number of cells in the leachate is less than 100 × 106 / L, and the number of cells in the exudate is more than 500 × 106 / L. 1. Red blood cells, such as more than 0.1 × 1012 / L, can be found in tumors, pulmonary embolism, trauma and tuberculosis. 2. White blood cells, such as more than 200 × 106 / L, can be found in tuberculosis, tumors, etc., such as more than 1000 × 106 / L, can be seen in purulent bacterial infections. 3. Classification 1 The number of neutrophils increased by 85% to 95%, which is seen in acute suppurative bacterial infection and early tuberculosis infection. 2 eosinophils such as increased by 2% to 5% or more, found in allergic diseases, parasitic diseases, repeated puncture collection of fluid, tuberculosis absorption period, pneumothorax, systemic lupus erythematosus, pulmonary infarction, fungal infection and Tumors, etc. 3 lymphocytes such as increased, found in tuberculosis, syphilis, tumors, myeloma and chronic non-tuberculous pleurisy. 4 mesodermal cells usually account for 15% to 20%, mostly in the leakage, also seen in the exudate, indicating that the pleura is stimulated. High results may be diseases: tumor, chronic suppurative pleurisy, tuberculous pleurisy, tuberculosis, pulmonary embolism Before the test: Eliminate tension. At the time of examination: cooperate with the doctor to withdraw the serous effusion. Not suitable for the crowd: no. Inspection process The puncture method is taken immediately after taking the serous effusion specimen. Generally, it is detected by microscopic counting method and specimen dilution method. The steps are as follows: 1. Preparation of bacterial suspension (yeast - take appropriate amount of bacterial liquid, serial dilution); 2, cleaning the counter - naturally dry; 3. Observe the counting chamber and add the sample (use a pipette to suck a small amount of bacterial suspension, add about 10ul sample from the sample (natural siphon)); 4. Microscope counting, averaging and calculating the original bacterial concentration. Not suitable for the crowd The people who need to be tested have tuberculosis, suppuration, bacterial infection, lung infection and other people with serous effusion, and those without detection indications should not be tested. Adverse reactions and risks 1. Infection: Pay attention to aseptic operation when puncture, pay attention to local cleaning after puncture, prevent water pollution and avoid infection. 2, bleeding: puncture needle damage to local blood vessels or tissue caused by local bleeding, should try to avoid puncture too deep.
