clinical study of stellate ganglion block in treatment of patients with advanced primary parkinson's disease

Conditions: Stellate Ganglion; Parkinson Disease

Summary: at present, there are no reports on the application of stellate ganglion block in the treatment of parkinson's disease patients at home and abroad. based on the preliminary clinical observation, this project intends to apply stellate ganglion block in the treatment of patients with intermediate and advanced parkinson's disease through an open, randomized controlled small sample clinical study. to determine whether stellate ganglion block can effectively improve motor symptoms and non-motor symptoms in patients with primary advanced parkinson's disease.

parkinson's disease (pd) is a relatively common degenerative disease of the central nervous system. in the past few decades, china's population has increased significantly, resulting in a rapid increase in the number of elderly people. according to the 2016 global burden of disease study, the number of pd patients in china accounts for about 23% of the global pd population. by the end of 2020, the estimated number of people living with parkinson's disease in china is about 3.62 million, and it is expected that by 2030, 50% of the world's pd patients will be chinese. the main manifestations of parkinson's disease are motor symptoms such as bradykinesia, myotonia and tremor, and non-motor symptoms such as autonomic nervous dysfunction, sleep disturbance and anosmia. both motor symptoms and non-motor symptoms can significantly affect patients' quality of life. at present, the domestic and foreign treatment guidelines for parkinson's disease still prefer drug therapy represented by dopa. however, in the middle and late stages of the disease, side effects such as symptom fluctuation or hyperactivity disorder complicated by long-term drug use gradually appear, and the efficacy of patients on levodopa declines, which seriously affects the quality of life of patients. for patients with advanced parkinson's disease, current anti-parkinson's guidelines advocate a combination of drug therapy and non-drug therapy. as a major non-drug treatment for parkinson's disease, deep brain stimulation (dbs) has limited its wide clinical application due to its complex, invasive, expensive, and many side effects, while conventional rehabilitation therapy is limited to functional exercise such as speech and swallowing, with limited efficacy. therefore, the search for new treatments for parkinson's disease is imperative. at present, there are no reports about the application of sgb in the treatment of patients with parkinson's disease at home and abroad. based on the preliminary clinical observation, this study intends to apply sgb in the treatment of patients with advanced parkinson's disease through an open, randomized controlled small sample clinical study, so as to confirm that sgb can effectively improve the motor symptoms and non-motor symptoms of patients with advanced parkinson's disease.
