Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Electroencephalographic recordings (EEG) present an opportunity to monitor changes in human brain electrical activity during changing states of consciousness during general anesthesia.

The investigators aim to determine if EEG-guided anaesthesia using the Masimo Sedline Root monitor will result in different anaesthetic requirements, different anaesthetic depth, and emergence characteristics in children under 16 years of age.

200 children under 16 years undergoing routine general anaesthesia under sevoflurane will be randomized to either EEG monitoring or routine care. We will compare the anaesthetic requirements, the patient state index, number of episodes of burst suppression and the incidence and severity of emergence delrium between the two groups.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Electroencephalographic recordings (EEG) present an opportunity to monitor changes in human brain electrical activity during changing states of consciousness during general anesthesia.

At present, monitoring of the brain under anaesthesia is not routinely employed. Since every patient is different and the way their brain response to anaesthetic drugs is different, it is important to adjust the patients' anaesthetic depth according to their brains' response, rather than only relying on routine cardiorespiratory parameters. This is important particularly for children, whose physiological responses and electroencephalographic recordings (EEG) differ from that of adults.

200 children under 16 years undergoing routine sevoflurane general anaesthesia will be randomized to either EEG-guided anaesthesia or routine care. The investigators will compare the anaesthetic requirements, the patient state index, number of episodes of burst suppression and the incidence and severity of emergence delrium between the two groups.

The subject and the outcome assessor analysing the EEG subsequently will be blinded to group allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

EEG-Guided Anaesthesia

Patients will have Sedline EEG sensor placed and anaesthesia guided by the EEG characteristics, patient state index (PSI) and suppression ratio (SR), in addition to routine clinical parameters.

Group Type EXPERIMENTAL

Sedline EEG sensor placement

Intervention Type DEVICE

Patients will have Sedline EEG sensor placed before or immediately after induction.

Sedline EEG monitoring

Intervention Type DEVICE

Anaesthesia depth will be guided by EEG characteristics in addition to routine clinical parameters

Routine Care

Patients will have Sedline EEG sensor placed but the monitor is concealed so the clinician is blinded to the EEG response. Anaesthesia is guided by routine clinical parameters.

Group Type ACTIVE_COMPARATOR

Sedline EEG sensor placement

Intervention Type DEVICE

Patients will have Sedline EEG sensor placed before or immediately after induction.
