Patients who suddenly experience dizziness and unsteadiness should look for the cause and treat the cause. In this case, the cerebellum and vestibular lesions are more likely to occur, because the cerebellum and vestibular is an important organ to maintain the balance of the human body: 1, if the patient is caused by cerebellar infarction, it is recommended that the patient use rt-PA or urokinase to carry out intravenous thrombolysis in the acute stage, to restore the patient’s cerebral blood supply. 2, if it is the hemorrhage of cerebellar area, the patient should be immediately bedridden, and at the same time give the The patient dehydration, lowering cranial pressure to carry out treatment, because the cerebellum from the brain stem position is relatively close, once the cerebellum formed edema, easy to compress the brain stem and lead to sudden death. Therefore, if the amount of bleeding is large, it is necessary to consider treatment through surgical removal of hematoma to save the patient’s life.3. If the patient is suddenly dizzy and unsteady, if it is considered to be a vestibular organ disease, such as otolithiasis, it can be treated through manipulation of repositioning. And if it is Meniere’s disease, use Valium and Isoprozine to give the patient anti-dizziness and anti-emetic treatment.
