Vagus nerve examination

The vagus nerve dominates breathing, digesting most of the organs of both systems, as well as the heart's sensation, movement, and glandular secretion. The vagus nerve has many functions that are closely associated with the glossopharyngeal nerve. The vagus nerve examination determines whether the vagus nerve is damaged by the patient's pronunciation and response to the bilateral posterior pharyngeal wall. First pay attention to whether the patient speaks nasal, hoarseness or aphasia, difficulty swallowing, drinking water and coughing. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Reminder: In the inspection, cooperate with the doctor to send the "ah" sound and swallow, drink and other actions. Normal value When the bilateral posterior pharyngeal wall is touched, the normal reaction is soft palate, nausea and vomiting. Clinical significance Abnormal result 1. When the vagus nerve is damaged, the pronunciation is hoarse, the voice is nasal, the dysphagia is swallowed, the drinking water coughs, the pharyngeal sensation is lost, the pharyngeal reflex disappears; the soft palate movement is limited, one side of the paralysis is light, and the soft palate on the side of the palate is visible when opening the mouth. The bow is lower, and the uvula is perpendicular to the healthy side. When the pronunciation of "ah" is pronounced, the soft side of the sacral side is lifted normally, the side of the disease is restricted, the sacral side is moved to the side, the pharyngeal sensation is absent, and the pharyngeal reflex disappears. 2, vagus nerve damage, and no long bundle sign, often suggesting brain neuropathy. Unilateral cortical medullary bundle lesions showed no glossopharyngeal nerve and vagus nerve paralysis, because the glossopharyngeal nerve and vagus nerve nucleus were both innervated cortical medullary bundles. Symptoms and signs of pseudobulbar paralysis (pseudobulbar palsy) occurred in the bilateral cortical medullary bundle lesions. People who need to be examined: patients with hoarseness, nasal vocalization, difficulty swallowing, loss of pharyngeal sensation, loss of pharyngeal reflex, and limited movement of soft palate. Precautions Contraindications before inspection: The tongue depressor should be disinfected before inspection. Requirements for inspection: When checking, cooperate with the doctor to send "ah" sound and swallow, drink and other actions. Inspection process First pay attention to whether the patient speaks nasal, hoarseness or aphasia, difficulty swallowing, drinking water and coughing. Then check whether the pharyngeal muscles are atrophy, whether the position of the uvula and the height of the soft palate are symmetrical. Then ask the patient to make an "ah" sound, pay attention to whether the squat is centered, and whether the height of the soft sputum on both sides is consistent. Finally, the pharyngeal reflex was examined, and the posterior pharyngeal wall was touched by the tongue depressor respectively. The normal reaction was soft palate rise, nausea and vomiting. Not suitable for the crowd Inappropriate population: Patients with severe oral ulcers or other lesions. Adverse reactions and risks Nothing.
