Cerebrospinal fluid specific gravity

The cerebrospinal fluid obtained from different puncture sites differs slightly depending on the protein content. For example, the cerebrospinal fluid obtained from lumbar puncture is 1.006 to 1.008; the perforator is 1.004 to 1.008; and the lateral ventricle is 1.002 to 1.004. In intracranial inflammation, the specific density is increased; when the secretion of cerebrospinal fluid is increased, the specific density is reduced. Basic Information Specialist classification: growth and development check classification: cerebrospinal fluid examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: No relevant information. Normal value: Cerebrospinal fluid specific gravity: 1.005-1.009 Above normal: Found in meningitis, uremia, diabetes. negative: Positive: Reminder: specimens should be sent immediately after collection, generally should not exceed 1h, so as not to be placed for too long to cause cell destruction, glucose decomposition or clots affect the inspection results. Normal value 1.005~1.009. Clinical significance Abnormal result (1) elevated in meningitis, uremia, diabetes. (2) Reduced rare. Need to check the crowd Patients with high fever and renal dysfunction. High results may be diseases: meningitis, uremia considerations Requirements for inspection: 1, the specimen should be sent immediately after the collection, generally should not exceed 1h, so as not to be placed for too long to cause cell destruction, glucose decomposition or clots affect the inspection results. 2, if necessary, cerebellar medullary puncture (pool wear) or lateral ventricle puncture. Preparation before inspection: 1. Tell the doctor about the history of the medicine and the medical history. Inspection process 1. Open the hand-held refractometer cover. 2. Carefully dry the prism glass surface with clean gauze or roll paper. Drip 2 drops of distilled water on the prism glass surface and cover the cover. In the horizontal state, observe from the eye joint to check whether the boundary between the light and dark in the field of view is at If the zero line does not coincide with the zero line, turn the scale to adjust the spiral so that the boundary line just falls on the zero line. 3. Open the cover and dry the water with gauze or roll paper, then drop on the prism glass as above. Not suitable for the crowd 1, intracranial hypertension caused by various reasons, especially those with optic nerve head edema. 2, lumbar tuberculosis or puncture site infection. 3, the whole body condition is not allowed to puncture. 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.
