Region	Japan

Condition
Condition	Of patients who are undergoing elective breast surgery, participants are included if they have both of the following: 1) American Society of Anesthesiologist (ASA) physical status (PS) classification 1 or 2 2) Capability of providing written consent before participation to this study
Classification by specialty	Anesthesiology
Classification by malignancy	Malignancy
Genomic information	NO

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 (from the beginning of operations to 10 minutes after), 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) and Bispectral Index (BIS) 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.
