brainstem reflex examination

The presence or absence of normal brain reflex and pathological nerve reflex is important for judging the degree of damage or inhibition of cranial nerve function, and then making corresponding judgments on the prognosis of patients. It is also to judge the coma level of the patient (cortex, Interbrain, midbrain, pons, and brain) and an important basis for determining brain death. Examination of brain stem reflex helps clinicians better grasp the patient's condition in medical practice, so as to better grasp clinical medicine. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Adjust your emotions before checking, don't be too nervous and worried. Normal value The results of each inspection are consistent with the standard measurement results. Clinical significance Abnormal results: pathological palmar reflex showed cortical-subcortical involvement; vertebral reflex, palmar reflex disappeared and lesion spread to the diencephalic plane; frontal rim muscle reflex, vertical vestibular reflex disappearance and corneal mandibular reflex It appears as a feature of the midbrain-middle-brain plane involvement; the pupil has a lesion on the disappearance of light reflex and corneal mandibular reflex and spread to the midbrain; corneal reflex, chewing muscle reflex, and corneal mandibular reflex disappeared to indicate plane involvement on the pons; horizontal anterior The reflection of the court disappeared and the plane under the brain was involved; the reflex of the eye was disappeared, the sputum was dilated, the breathing stopped to show the brain damage, and the brain died. People who need to be examined: Patients with suspected brain lesions. Precautions Taboo before check-up: Adjust your emotions before you check, don't be too nervous and worried. Requirements for inspection: 1. Check too many items, and have patience to finish the items that need to be checked. 2. If there is pain and convulsion during the examination, please inform the doctor in time so that the doctor can make the correct diagnosis and treatment. Inspection process Ciliary Spinal Reflex (CSR): Pain stimulates the supraclavicular area causing ipsilateral pupil dilation. Significance: This reflection disappears suggesting that damage extends to the diencephalic plane. Forehead muscle reflex (FOMR): When examining, use the finger to pull the outer skin of the patient's eyebrow outward and upward and fix it, then use the deduction hammer to gently buckle the finger, causing the ipsilateral eye muscle to contract and close the eye. Significance: This reflex disappears into the inter-brain-middle brain plane involvement. Vertical vestibular reflex (VOVR): When the patient leans or leans back, the movements of both eyes and the head move vertically in the opposite direction. Significance: This reflex disappears into the inter-brain-middle brain plane involvement. Pupil-to-light reflection (PLR): Light stimulation causes the pupil to shrink. Significance: This reflection disappears as a manifestation of damage to the midbrain plane. Corneal reflex (CR): Use cotton to gently touch the cornea to close your eyes. Significance: This reflection disappears and the pons plane is damaged. Chewing Muscle Reflex (MR): The crotch muscle contraction with the ankle. Significance: The disappearance of reflection is the involvement of the pons plane. Horizontal vestibular eye reflex (HOVR): When the head moves to the left or right, the double eyeball moves horizontally in the opposite direction. Significance: This reflection disappears suggesting that the lower plane of the pons is involved. Eye Reflex (OCR): Compression of the eye causes a slowing of heart rate. Significance: This reflection disappears as a manifestation of impaired medullary plane. Palmar Reflex (VMR): Lightly stroke the large fish area of ​​the palm causing contraction of the ipsilateral diaphragm. Significance: The appearance of this reflex suggests a cortical-cortical plane involvement. Corneal mandibular reflex (CMR): Lightly touching the cornea causes the eye to close, and causes the extrafusal muscle to contract, causing the mandible to move to the opposite side. Significance: This reflex appears as a manifestation of the midbrain-middle and midbrain plane involvement. The first 8 species are physiological reflexes, which can disappear in the course of brain stem injury. The latter two are pathological reflexes that occur when the injury affects the brainstem. According to the examination results, the dysfunction plane is divided into the top-down: cortex-cortical plane, interventricular plane, midbrain-middle brain plane, midbrain plane, pons plane, and cerebral plane. Not suitable for the crowd Inappropriate population: Patients with disabilities on their limbs or disease. Adverse reactions and risks Nothing.
