General anesthesia is a medically induced state of low reactivity consciousness which is similar to natural sleep. Some studies found that general anesthesia as an independent risk factor could result in a desynchronization of the circadian time structure and cause postoperative sleep disorders characterized by reduced rapid eye movement (REM) and slow wave sleep (SWS), which have significant deleterious impacts on postoperative outcomes, such as postoperative fatigue, severe anxiety and depression, emotional detachment and delirium, and even pain sensitivity or postoperative pain of patients.Clinical trials have already proved that intraoperative use of dexmedetomidine (DEX) for general anesthesia, a highly selective alpha-2 adrenergic agonist, was able to improve sedative and analgesia effects and promote sleep quality (by decreasing stage N1 sleep, increasing stage N2 sleep and sleep efficiency). However, Wenfei Tan et al reported that with the deeper sedative state provided by DEX in the daytime, the elderly male patients undergoing TURP under spinal anesthesia suffered worse sleep on the night of surgery. Thus, what the effect of intraoperative using DEX at different time periods under general anesthesia on postoperative sleep quality and pain will be needs further study.

Primary | Sleep quality of third night after the surgery | Use sleep monitor to test the sleep quality on the third night after the surgery | the third night after the surgery | |
Secondary | Visual analog scale (VAS) | Evaluate the VAS score at 1,6,24,48 hours after the surgery.Visual analog scale (VAS) score of 0 was considered painless, and a score of 10 was considered as intense pain. Scores of 4 and below were considered mild pain (pain does not affect sleep), and scores of 5 to 6 were considered moderate pain (pain influences sleep, but the patients can still fall asleep). Scores of 7 and above were considered severe pain (Due to the pain the patient is unable to sleep or wakes up) | 1,6,24,48 hours after the surgery | |
Secondary | PCA pump press number | Evaluate the Pump press number 48 hours after the surgery | 48 hours after the surgery |
