A “stroke unit” is a medical complex with standardized treatment protocols and clear treatment goals for stroke patients within a certain area of a hospital. It is a comprehensive management system for stroke patients that extends to the recovery and post-stroke periods, and includes community care, family care, and various treatment facilities. A stroke unit is a medical complex that is based on neurology and NICU, with standardized and clear treatment goals for stroke patients, and multidisciplinary discussion and care by neurology, emergency medicine center, neurointerventional treatment team, rehabilitation department, and neurosurgery. The stroke unit is not a specific therapy, but a scientific management system for stroke patients, which fully reflects the concept of human-centered medical service and comprehensive multidisciplinary treatment. The main objectives are to save brain damage, prevent complications, reduce mortality, treat patients in the NICU for 3 to 7 days, and link them to the general neurology ward. The main operation process includes: 1. Nurse in the emergency medical center: 1. Receive – notify the chief neurologist; 2. Open intravenous access and take blood specimens; 3. Monitor vital signs; 4. Severely impaired consciousness or respiratory and circulatory failure: send to the intensive care unit. 2. Consult the chief resident of neurology: 1. Take medical history; 2. Vital signs and general examination; 3. Neurological assessment: determine whether it is a stroke; time of stroke onset, onset of stroke.
