Microbiological examination of pleural effusion

Microbiological examination of pleural effusion is a method for examining common pathogenic bacteria such as Staphylococcus, Streptococcus, Escherichia coli, Bacteroides fragilis, and Pseudomonas aeruginosa. For the effusion suspected of exudate, it is generally necessary to do a biological examination of the pathogen. It is suspected that bacterial infection can be cultured in bacteria. Tuberculous pleural effusion, centrifuged to take a smear of the sediment, acid-fast staining, microscopic acid-fast bacilli can be found under the microscope. Common pathogens in suppurative exudate include staphylococcus, streptococcus, Escherichia coli, Bacteroides fragilis, Pseudomonas aeruginosa, etc. In a few cases, there may be anaerobic or actinomycetes infection. Basic Information Specialist classification: Respiratory examination classification: chest and ascites examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The result of the negative test is generally normal. Positive: The positive test results suggest that there may be diseases such as empyema, pleurisy, tuberculosis, and pulmonary infarction. Tips: Pay attention to normal eating habits and pay attention to personal hygiene. Normal value The normal test result is negative. Clinical significance In pathological conditions, such as increased cistern capillary hydrostatic pressure or decreased colloid osmotic pressure, or increased intrathoracic negative pressure and pleural effusion pressure in the pleural fluid, can lead to excessive production of pleural fluid and significant reduction in absorption, resulting in pathological Pleural effusion (pleuraleffusion), also known as pleural effusion. Common causes are pleural or adjacent tissue infections, primary or metastatic tumors. In addition to traditional cytology, biochemistry, and microbiological examination, pleural effusion examinations have been developed to apply immunological and molecular biological methods to further distinguish the nature of effusions. Abnormal results of empyema, pleurisy, tuberculosis, pulmonary infarction, chest metastases or primary malignant tumors, fungal infections, bacterial pleurisy, chylothorax, esophageal perforation, uremic pleural effusion. The people in need of examination have patients with pleural effusion caused by pathogenic microorganisms such as empyema, pleurisy, tuberculosis, and pulmonary infarction. Positive results may be diseases: tuberculosis, hollow tuberculosis, chylothorax considerations Forbidden before examination: Pay attention to normal eating habits and pay attention to personal hygiene. Requirements for inspection: Actively cooperate with the doctor. Pleural effusion specimen collection was obtained by thoracentesis. Immediately after the specimen is taken, it should be sent for inspection to prevent cell degeneration, destruction or clot formation and affect the result. Inspection process For the effusion suspected of exudate, it is generally necessary to do a biological examination of the pathogen. It is suspected that bacterial infection can be cultured in bacteria. Tuberculous pleural effusion, centrifuged to take a smear of the sediment, acid-fast staining, microscopic acid-fast bacilli can be found under the microscope. Common pathogens in suppurative exudate include staphylococcus, streptococcus, Escherichia coli, Bacteroides fragilis, Pseudomonas aeruginosa, etc. In a few cases, there may be anaerobic or actinomycetes infection. Not suitable for the crowd The test is less invasive and generally has no specific contraindications. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
