Study on the Effect of EEG Bispectral Index Monitor in the Adjustment of Anesthesia Depth in Laparoscopic Surgery
Objective:To study the effect of EEG bispectral index(BIS)monitor on depth adjustment of anesthesia in laparoscopic surgery.Methods:A total of 65 patients treated with laparoscopic surgery from January 2021 to February 2023 were selected to carry out the experiment.They were randomly divided into study group(n=32)and reference group(n=33).The reference group received routine anesthesia management,and the study group received BIS monitor anesthesia management.Hemodynamics,clinical indices,serum levels of interleukin-6(IL-6),S-100β and myelin basic protein(MBP),cognitive function were compared between the two groups.Results:At T2,T3 and T4,the hemodynamic indexes in the study group were lower than those in the reference group.The recovery time,extubation time and PACU departure time in the study group were shorter than those in the reference group.The levels of serum in the study group were lower than those in the reference group 3 days after operation.The MMSE score of the study group was higher than that of the reference group 1 and 3 days after operation.The above differences were significant(all P<0.05).Conclusion:BIS monitor has a significant effect on the adjustment of anesthesia depth in laparoscopic surgery patients.
