Study Overview
Brief Summary
To compare the accuracy of frontal versus nasal BIS monitoring in pediatric patients under general anesthesia.
Detailed Description
Standard position of frontal bispectral index (BIS) may not be available in some operations that frontal area is occupied by surgical field. This prospective cohort study aims to compare the accuracy of the BIS between an alternative position across the nasal area with the standard frontal BIS position in pediatric patients undergoing general anesthesia.

Arms & Interventions
BIS
The patients will receive both standard frontal and nasal BIS monitoring during general anesthesia.
Intervention: Bispectral index (BIS) (Device)
Outcomes
Primary Outcomes
bispectral index (BIS) value
Time Frame: 5 hours
BIS is a processed electroencephalogram (range from 0-100), the optimal value of BIS during general anesthesia is 40-60. We aim to define the differences between standard frontal BIS and nasal BIS using Bland-Altman analysis.
Secondary Outcomes
- signal quality index (SQI)(5 hours)
- electromyography (EMG)(5 hours)
