Abstract: Objective To evaluate the role of bispectral index (BIS) in assessing the depth of sedation in hypogastric operation of children. Methods Forty children undergoing hypogastric operation were divided into two groups with 20 cases each by pre-school (age 3-5) (Ⅰ group) and school (age 6-12)(Ⅱ group). Sedation was solely maintained with TCI propofol. The infusion was adjusted till adequate scdation (OAA/S≤ 1 score) before sacral block. The course of propofol infusion and BIS of recovery period were closely observed. Sedation scores were assessed by special anesthetists. Results During recovery period, the mean values of BIS were gradually increased, when BIS > 76 predicted 94% sensitivity and 50% specificity in Ⅰ group, 100% sensitivity and 100% specificity in Ⅱ group. ROC area under the curve of the two groups were 0.917 ± 0.007, 0.955 ± 0.004. Conclusions BIS can predict fairly well the level of consciences during recovering periods. BIS monitoring is an effective and reliable method to guide children recovery.
