Li Wensheng test

This test is a simple differential diagnosis and treatment aid for tuberculous meningitis and purulent meningitis. It should be considered when the laboratory conditions are poor. Basic Information Specialist classification: examination classification: cerebrospinal fluid examination Applicable gender: whether men and women apply fasting: fasting Tips: Actively cooperate with doctors. Normal value Normal cerebrospinal fluid two tube sediments are small, generally not more than 2mm. Clinical significance Abnormal results: (1) If the sulfosalicylic acid tube sediment is twice or more than the mercury chloride tube, it is mostly purulent meningitis. (2) If the mercury chloride tube sediment is twice or more than the sulfo-salicylate tube, it is mostly tuberculous meningitis. (3) The precipitation in the two tubes is similar, and the diagnosis cannot be distinguished. Need to check the population of people with suspected meningitis. High results may be diseases: tuberculous meningitis, suppurative meningitis considerations Taboo before the examination: It is necessary to cooperate with the doctor to write the correct name, neat and tidy, to avoid confusion caused by the same name or similar names. Paying attention to these will make it easier and faster to save yourself time for diagnosis. During the examination, when the protein in the cerebrospinal fluid increases, the alkaloid precipitate formed by sulfosalicylic acid forms fast, heavy and solid; the metal precipitate formed by mercury chloride is flocculent, forms slower and adheres to the tube. wall. Inspection process Both sulfosalicylic acid and chlorinated high mercury can precipitate proteins in cerebrospinal fluid. According to the ratio of precipitates in the two tubes, tuberculous meningitis and purulent meningitis can be identified. Not suitable for the crowd 1. If there is obvious papilledema or cerebral palsy, contraindications are contraindicated. 2. Patients who are in shock, exhaustion or endangered state and local skin inflammation, and lesions in the posterior cranial fossa are contraindicated. Adverse reactions and risks If the patient has symptoms such as breathing, pulse, or abnormal color during puncture, stop the operation immediately and deal with it accordingly.
