Abstract：Objective To investigate the cognitive status of some medical staff in more than 1 500 hospitals in China about EEG monitoring for patients undergoing general anesthesia/sedation,and provide decision basis for further use of EEG monitoring.Methods A self-designed questionnaire was used to investigate the cognition and application of EEG monitoring in patients undergoing general anesthesia/sedation among medical staff in more than 1 500 hospitals in 29 provinces in China in November 2023.The questionnaire contained 5 parts and 32 items.Results A total of 3 315 questionnaires were collected in this survey.Up to 97.98％of the respondents understood the EEG monitoring equipment,of which 68.45％clearly understood.Precisely 47.17％of the medical staff knew both the EEG monitoring equipment and its working principle,and 90.38％of the medical staff believed that EEG monitoring could reduce the incidence of intraoperative awareness.Precisely 90.29％and 86.61％of the medical staff considered that patients with weak and fragile brain function needed EEG monitoring,respectively.Different anesthetics were considered to be the first factor affecting EEG monitoring,and 93.48％of the medical staff believed that it had an impact on EEG monitoring.Precisely 95.93％of the medical staff thought that the elderly patients should undergo routine EEG monitoring,and 95.14％of the participants agreed that EEG monitoring combined with other monitoring could provide more accurate anesthesia.Conclusion The medical staff in major hospitals in China,mainly anesthesiologists,have a better understanding of EEG equipment and a more positive attitude towards its role,but the understanding of its principle needs to be improved.Most anesthesiologists agree that EEG monitoring may benefit elderly patients and patients with weak and fragile brain function,but it is easily affected by factors such as anesthetics.
