| Objective:In recent years,it is a hot research topic to analyze the effect of traumatic stimulation on brain waves by monitoring brain waves.The purpose of this study was to monitor the changes of alpha and beta waves of brain waves when different traumatic stimuli were applied to surgical patients,in order to explore the sensitivity index of brain waves to traumatic stimuli.Methods:Twenty laparoscopic patients were selected for anesthesia induction using midazolam,etomidate,rocuronium bromide and lidocaine,while propofol and remifentanil were used for anesthesia maintenance,and brain waves in the frontal region were collected.The patients were subjected to ciliary stimulation(Mark2),tracheal intubation(Mark4,Mark5),and cuticle resection stimulation(Mark6,Mark7).The EEG waves during stimulation were intercepted,and the changes of α wave and β wave power of EEG before and after traumatic stimulation were analyzed,and the sensitivity of α wave andβ wave to traumatic stimulation was compared.Results:The power of β wave was more obvious than that of α wave in ciliary and intubation stimulation(P < 0.05).There was no significant difference between α wave power and βwave power during dermectomy(P > 0.05).Conclusion:Pain stimulation can increase β wave power and decrease α wave power,and the change of β wave power is more obvious than α wave power. |
