Pseudomyelination palsy is a condition in which the medulla oblongata swallowing center is not involved in cerebrovascular disease, but the stroke has damaged the medulla oblongata bundle bilaterally, causing dysfunction of the nucleus suspensus, which governs the movement of the pharyngeal muscles, and the nucleus of the hypoglossal motor nerve, which governs the lingual muscles, making swallowing and articulation difficult. What tests are needed for pseudomyelinating palsy? Not knowing the order of eating, repeating the same action, talking during eating to increase the risk of mis-swallowing, easily ignoring food on one side of the table, normal function of the tongue and biting muscles but unable to swallow food stuffed in the mouth. 1, ENT examination: ENT examination must be careful because the ear, nose and throat are deep in tiny cavities, so special lighting devices and examination instruments must be used for examination, commonly used are 100-watt inspection lamp with spotting lens, frontal mirror, otoscope, bulging otoscope, gun-like forceps, rolled cotton, cerumen hook, tongue depressor, anterior rhinoscope, posterior rhinoscope, indirect laryngoscope, tuning fork, nebulizer, etc. 2.Blood routine: blood test is to detect and analyze the quantity and quality of the three systems of the blood’s organic components, namely red blood cells, white blood cells and platelets. 3, blood electrolyte test: blood electrolyte test is to detect the content of various electrolytes in human blood, such as kidney disease, diabetes, endocrine diseases. Generally, blood is collected from a vein for testing. Blood glucose, 4, cerebrospinal fluid examination: cerebrospinal fluid examination (examination of cerebrospinal fluid), the cerebrospinal fluid pressure measured after puncture, side-lying adults for 0.78-1.76kPa (80-180mm water column), infants have for children for 0.39-0.98kPa (40-100mm water column), newborns for 0.098-0.14kPa (10-14mm water column). When observing the initial pressure, attention should be paid to the presence or absence of respiratory pulsation of the cerebrospinal fluid surface (pulsation of the fluid surface with respiration of 0.098-0.197 kPa (10-20 mm water column) and pulsatile pulsation (pulsation of the fluid surface with pulse of 0.02-0.039 kPa (2-4 mm water column); when the former disappears, it suggests an obstruction in the spinal canal or an occipital foramen herniation, both of which should be treated with caution. Cerebrospinal fluid is collected by lumbar puncture performed by a clinician, and can be obtained from the cerebellar ventricular pool or lateral ventricle puncture if necessary.
