Interventions/Control_1

Intervention is performed during general anesthesia; in the N2O group, general anesthesia is maintained with 60% N2O and 40% FIO2 after tracheal intubation. N2O administration will be terminated immediately after the end of surgery.

Interventions/Control_2

Intervention is performed during general anesthesia. In the air group, general anesthesia is maintained at 40% FIO2 by mixing air and oxygen after tracheal intubation. Air administration will be terminated immediately after the end of surgery.
