• Registration Number: NCT05179590
• Lead Sponsor: Beijing Friendship Hospital

Brief Summary

Patients frequently report having dreams during general anesthesia. The incidence of dreams during general anesthesia that have been reported by patients upon awakening has been reported to range from 10 to 36% \[1\] and to be higher in younger patients, female patients \[2\], and patients who received ketamine \[3\]. The quality of dreams during general anesthesia is often reported as pleasant, but some patients report unpleasant or not pleasant dreams \[4, 5\]. However, the factors associated with the quality of dreams have remained to be elucidated. Therefore, the aim of this study was to determine the relationships between the quality of dreams during general anesthesia and perioperative factors.
