Routine examination of synovial fluid

The joint cavity is surrounded by the articular surface and the synovial membrane, and contains synovial fluid. When joints develop inflammation and other diseases, the synovial membrane is often involved, and its normal chemical composition and cellular components change. Therefore, the analysis of synovial fluid has practical clinical value for the diagnosis of joint diseases. The analysis of synovial fluid by joint puncture is of great significance for the diagnosis of joint diseases. Basic Information Specialist classification: growth and development check classification: body fluid examination Applicable gender: whether men and women apply fasting: not fasting Tips: Less exercise to cause trauma or strain before the examination, reduce joint weight and flexion and extension activities. Normal value White blood cells <100 × 106 / L (<100 / mm3). Polymorphonuclear leukocytes <0.25 (<25%). Protein quantification <25 g/L (<2.5 g/dl). Mucin 1 or 2 type. Crystallization 0. Glucose 0.56 mmol/L (10 mg/dl). Clinical significance 1, leukocytosis (200 ~ 2000) × 106 / L non-inflammatory arthritis. (2000 ~ 75000) × 106 / L inflammatory arthritis. >100000×106/L septic arthritis. 2. Polymorphonuclear leukocytes >0.50 inflammatory arthritis. >0.75 septic arthritis 3, protein quantitative rheumatoid arthritis or crystalline synovitis (such as gout) protein quantitatively increased, often up to 40 ~ 70g / L, mildly elevated degenerative arthritis. 4, mucin clot formation is poor or brittle, found in inflammatory arthritis, septic arthritis. 5. Crystalline gouty arthritis (urate crystal), calcium pyrophosphate deposition disease (false gout) (pyrophosphate crystal), chronic rheumatoid arthritis (cholesterol crystal). 6, glucose reduces inflammatory arthritis, septic arthritis. Precautions Before the examination: less exercise that causes trauma or strain, reduce joint weight and flexion and extension activities. When checking: 1. Orientation: In arthroscopic examination, since only a small part of the joint can be seen, it is not easy to judge which part of the joint image belongs to at the beginning of the examination, between the upper sac and the sac. Sliding film wrinkles are a good sign and easy to position. 2, synovial congestion: arthroscopy, because physical stimulation will affect the visual field, and liquid temperature, hydraulic pressure can also affect blood flow, therefore, synovial congestion 10 minutes after arthroscopy insertion should be considered normal. 3, age factors: with age, the image of the joint is different, the cartilage surface of children is smooth and elastic, the supraorbital sac is smooth, less fluff, adult, especially the elderly, the articular cartilage surface is yellow, rough The feathers are more, the meniscus is also the same, the inner edge is meat-like, the synovial folds are more, the villus hyperplasia, and the joint capsule is poorly stretched. 4. Individual differences in internal structure: There are three main types of normal synovial folds, namely, supraorbital synovial folds, lateral synovial folds, and sacral membrane folds, all of which are residual parts of the synovial membrane during development, synovial folds Some people have, some people have no. After the examination: the condition can be alleviated by various therapies such as drugs, massages and the like. Inspection process In the diagnosis and treatment of joint disease development, arthroscopy drugs can be approved multiple times, which can be obtained by video recording or synovial biopsy. The data that are difficult to obtain with other diagnostic methods are of great help to the diagnosis and treatment and prognosis. Some lesions of the knee and shoulder joints can be operated with special instruments under the microscope after careful diagnosis and discharge, and satisfactory results are obtained. Not suitable for the crowd Joint stiffness. Adverse reactions and risks Generally no complications and harm.
