Effects of dexmedetomidine, propofol and etomidate on the intraoperative wake-up in the cerebral functional area under the guidance of entropy index

摘要

Objective: The study observed the efficacy and safety of dexmedetomidine, propofol and etomidate on brain functional areas in patients undergoing wake-up brain surgery under the guidance of entropy index. Methods: Sixty patients undergoing wake-up brain surgery on brain functional areas were enrolled, and randomly divided into three groups: dexmedetomidine group (group D), propofol group (group P) and etomidate group (group E), 20 in each. The vital signs, entropy indices of each time point, wake-up time, wake-up quality and adverse reaction in the wake-up period were observed and compared. Results: There were no differences in the duration of wake-up, duration of anesthesia, duration of surgery and postoperative wake-up time between the three groups (P 0.05). The wake-up quality in group D was significantly better than group P and group E (P 0.05), group P was better than group E (P 0.05). The incidence of adverse events in group D was lower than that in groups P and E (P 0.05). The incidence of adverse events in group P was lower than that in group E (P 0.05). Conclusion: Under the guidance of entropy index, anesthesia induced by dexmedetomidine, propofol and etomidate combined with remifentanil can safely and effectively be used to the wake-up brain functional areas surgery, but the wake-up quality with use of dexmedetomidine is highest, and the incidence of adverse events is the lowest during wake-up period.
