Summary

The objective of this clinical trial is to investigate the effect of light exposure on sedation depth during general anesthesia.The primary research questions this study aims to address include: Does light condition affect the dosage of anesthetic medications during anesthesia? By what mechanism does light exposure exert an influence on anesthesia? Participants will be randomly allocated to either the light-shielded group or the non-light-shielded group.Patients in the light-shielded group will wear an eye shield during anesthesia. The following data will be recorded for all patients: Induction drug dosage Induction time Intraoperative anesthetic dosage Emergence time

Conditions

• Light
• Anesthesia
• Sedation

Interventions

Type	Name	Description
DEVICE	eye mask	Patients in the light-shielded group will wear an opaque eye mask 30 minutes prior to induction of general anesthesia and continue to do so until the cessation of sedative medications for anesthesia.
