serous effusion glucose

Serous effusion glucose quantification refers to the detection of glucose in the effusion to distinguish between leachate and exudate. The serosal cavity of the human body has pleural cavity, pericardial cavity, peritoneal cavity, joint cavity, scrotal sheath cavity and the like. Under normal conditions, there is only a small amount of liquid in the cavity, which acts as a slip. However, under pathological conditions, there may be a large amount of fluid in the cavity, called serosal effusion, such as pleural effusion, ascites, pericardial effusion, scrotal hydrocele, and joint cavity effusion. Due to the different causes of effusion, it can be divided into two types: leakage liquid and exudate. The various components and properties are obviously different. Check the amount, appearance, pH, relative density, protein, glucose and microscopy of various effusions. The significance lies in the difference in the nature of the effusion, whether it is leakage or exudate, and then find out the cause and conduct diagnosis and treatment. Basic Information Specialist classification: Respiratory examination classification: chest and ascites examination Applicable gender: whether men and women apply fasting: fasting Tips: The doctor should take the serosal effusion with the doctor. Normal value Under normal circumstances, there is only a small amount of liquid in the serosa cavity, which plays a role in smoothing, and the glucose content (3.6-5.5 mmol/L) is similar to blood glucose. Clinical significance Abnormal results: Normal serous cavity fluid, glucose content (3.6 ~ 5.5mmol / L), similar to blood sugar. Leakage glucose content was slightly lower than blood glucose, but exudate glucose was significantly lower than blood glucose (<3.33mmol/L). In the exudate, the significant decrease in glucose content is due to the increased glycolysis of bacteria and inflammatory cells, the increased use of glucose by tumor cells, and the reduction of glucose transfer from plasma to the serosal cavity. Mainly seen in suppurative effusion, followed by tuberculous effusion. The pleural effusion glucose content is less than 3.33mmol / L, or the ratio of pleural effusion and serum glucose is less than 0.5, more common in rheumatoid effusion, malignant effusion, non-suppurative infectious effusion, esophageal rupture effusion. Low results may be diseases: acute septic arthritis, tuberculous pleurisy, rheumatoid arthritis in the elderly 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. Detection method: quantitative detection of glucose. Not suitable for the crowd Not suitable for people: people who need to be tested have cirrhosis, cardiac insufficiency, fatigue, low fever in the afternoon, weight loss, night sweats, skin, joints, visceral damage and so on. Those without examination 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.
