Abstract:
Objective To evaluate the agreement of bispectral index values recorded from tumor side and the contralateral areas during supratentorial craniotomy.Methods Thirty-five patients (16 males, 19 females, aged 18-65 years, ASA physical status Ⅱ or Ⅲ) scheduled for supratentorial tumor resection were enrolled in this study.Bispectral index (BIS) sensors were placed at bilateral frontal areas.The patients were anesthetized with propofol.From each BIS monitor, we collected data at each of four time stages: before the induction of anesthesia, before dura opening, removal of tumor and recovery of conscious.These data were compared using Bland-Altman analysis.Results Bland and Altman analysis revealed a BIS negative-bias (limits of agreement) of before induction-0.8(-7.2-5.7), before dura opening 0.6 (-8.3-9.5), and removal of tumor 1.5(-6.9-9.9), recovery of conscious 0.2 (-9.3-9.8).Conclusion There are significant agreement for BIS values between the frontal area of tumor side and the contralateral areas.BIS values can be used interchangeably between bilateral frontal.
