Objectives

Narrative objectives1

In the course of induction and maintenance of general anesthesia using remimazolam, frontal electroencephalograms (EEGs) during induction (from the start of remimazolam administration to loss of consciousness), maintenance , and emergence (from the end of remimazolam administration to recovery of consciousness) phases will be analyzed in order to investigate the relationship between estimated effect-site remimazolam concentrations and the EEG changes.

Assessment

Primary outcomes

The relationship between estimated effect-site remimazolam concentrations, and frontal EEG changes during general anesthetic induction, maintenance , and emergence phases, respectively.

Key secondary outcomes

The relationship between estimated effect-site remimazolam concentrations, and Patient State Index (PSI) during induction , maintenance , and emergence phases, respectively. The trend in EEG frequency change depending on age. The relationship between age and the time from the end of remimazolam administration to recovery of consciousness.

2) Capability of providing written consent before participation to this study

Key exclusion criteria

Participants are excluded if they have any of the following:
1) Contraindications listed on the package insert of remimazolam (hypersensitivity to any of the components of remimazolam, acute closed angle glaucoma, myasthenia gravis, shock, coma, or acute alcoholic poisoning accompanying suppressed vital signs)
2) Contraindication to benzodiazepine
3) History of long-term administration of benzodiazepine
4) Contraindication to fentanyl, remifentanyl, or rocuronium
5) Severe liver dysfunction, renal dysfunction, or heart disease that may affect the safety assessment of remimazolam
6) ASA PS>=3
7) Others that the investigators consider to be inappropriate for a participant of the study
