Background
Lumbar puncture (lumbar punture) is one of the examination methods commonly used in neurology department, and has important value in the diagnosis and treatment of nervous system diseases.
Lumbar puncture is usually performed in the lumbar lateral decubitus position from the waist 2 to the sacral 1 (mainly at the waist 3-4) in the intervertebral space. After local routine disinfection and anesthesia, a user wears a rubber glove and slowly pierces the needle by a No. 20 puncture needle (No. 21-22 for children) along the direction of the spinous process, and when the needle point meets sclerotin in the process of needle insertion, the needle is retracted to the subcutaneous part to be subjected to angle correction and then punctures. When the adult is inserted by about 4-6cm (about 3-4cm for children), the dura mater can be punctured to reach the subarachnoid space, the needle core is drawn out to flow out cerebrospinal fluid, after the pressure is measured and the fluid is slowly released (no more than 2-3ml), the needle core is put in and the puncture needle is pulled out. The puncture point is pressurized slightly to stop bleeding, and then is applied with a sterilized gauze and fixed with an adhesive plaster. Lying for 4-6 hours after operation. If the initial pressure exceeds 2.94kPa (300mm water column), the drainage is not suitable, and only the cerebrospinal fluid in the manometric tube is taken to send the cells for counting and quantifying the protein.
