The Effect of Intraoperative Use of Dexmedetomidine During the Daytime

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

patients scheduled for elective laparoscopic abdominal surgeries under general anesthesia were enrolled. Patients were randomized to receive operation in the D group (8:00-12:00) and the N group (18:00-22:00). The Portable Sleep Monitor (PSM) was performed on the following 3 nights: the night before surgery (Sleep1), the ﬁrst night after surgery (Sleep 2), and the third night after surgery (Sleep 3). Postoperative pain scores using visual analogue scoring scale, subjective sleep quality using the Athens Insomnia Scale, total dose of general anesthetics and PCA pump press numbers were also recorded. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
