Pediatric Frontal and Nasal Bispectral Index

December 12, 2024 updated by: Mahidol University

An Accuracy of Bispectral Index Monitoring in an Alternative Nasal Position Compared With Standard Frontal Position in Pediatric Patients Under General Anesthesia With Sevoflurane

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.

  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: BIS
The patients will receive both standard frontal and nasal BIS monitoring during general anesthesia.
  • All patient will receive standard monitoring (EKG, Blood pressure, pulse oximetry), and BIS transducer placement at standard frontal area before anesthesia.
  • Sedative medication can be given as appropriate.
  • Anesthesia induction by inhalation induction with sevoflurane (if intravenous line not presented) or intravenous induction with thiopental 5-6 mg/kg IV
  • Other medication including fentanyl 1 mcg/kg IV and cisatracurium 0.1-0.2 mg/kg IV will be given and the patient will be intubated.
  • The second BIS will be installed on the bridge of the nose and temporal on the same side as frontal BIS.
  • The patient will be maintained with sevoflurane and other anesthetic drugs as appropriate, adjusted per frontal BIS (40-60).
  • The frontal BIS and the nasal BIS will be measured until the endotracheal tube is being removed. If the patient has moved until it was impossible to measure the BIS or has any necessity to cancel the BIS measurement. The BIS measurement can be stopped.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
5 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
signal quality index (SQI)
Time Frame: 5 hours
SQI (range from 0-100) determines the quality of signal of the primary outcome (BIS). We aim to define the differences of SQI of BIS between standard frontal and nasal positions.
5 hours
electromyography (EMG)
Time Frame: 5 hours
EMG (range from 0-100) reports the interference of muscle activity on quality of the primary outcome (BIS). We aim to define the differences of EMG between standard frontal and nasal positions.
