Overview
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
