Trial summary

General anesthesia is a medically induced state of low reactivity consciousness involving amnesia, immobility, unconsciousness, and analgesia, which is similar to natural sleep. Its aim is to create a state of sensory deprivation to induce a lack of motor reaction to stimuli and to obtain an explicit amnesia. Read more about this study

About this study

Official title: Comparison of Morning Operation and Evening Operation on Postoperative Sleep Quality and Pain Under General Anesthesia: A Randomized Controlled Trial

General anesthesia is a medically induced state of low reactivity consciousness involving amnesia, immobility, unconsciousness, and analgesia, which is similar to natural sleep. Its aim is to create a state of sensory deprivation to induce a lack of motor reaction to stimuli and to obtain an explicit amnesia. 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.Several studies also indicated that circadian rhythms existed in human and controlled by a main internal central clock, the suprachiasmatic nuclei, located in the anterior hypothalamus, which produce and regulate biological rhythms such as sleep arousal, hormones and metabolism could also affect the dose of general anesthesics, which lead to different postoperative recoveries and may have different effects on postoperative sleep quality. Previous studies proved that postoperative sleep disturbances and poor sleep quality are associated with higher postoperative pain, changes in behavior and poor emotional well-being, which could further aggravate postoperative sleep quality. At present, there are few studies which are about the effect of circadian rhythm for different timing of surgery on intraoperative anesthestic requirement, postoperative sleep quality and pain under general anesthesia.

Read the detailed description

eighty-four patients scheduled for elective laparoscopic abdominal surgeries under general anesthesia were randomly assigned to receive operation in the Day Group (8:00-12:00) and the Night 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 postoperative adverse effect were also recorded

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. postoperative sleep quality of one night before surgery

    Use sleep monitor to test the sleep quality one night before surgery

    Measured: one night before the surgery

  2. postoperative sleep quality of the first night after surgery

    Use sleep monitor to test the sleep quality the first night after surgery

    Measured: the first night after surgery

  3. postoperative sleep quality of the third night after surgery

    Use sleep monitor to test the sleep quality the third night after surgery

    Measured: the third night after surgery

Secondary outcomes (2)
  1. intraoperative general anesthestic requirement

    record the total dose of general anesthestic requirement during the operation

    Measured: during the surgery

  2. postoperative adverse effect

    record the postoperative adverse effect

    Measured: 24 hours after the surgery

Questions about this trial

What is this clinical trial studying?

A study testing receiving operation during the day or at night in people with Morning Operation and Evening Operation, run by Shengjing Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

postoperative sleep quality of one night before surgery (time frame: one night before the surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Apr 2020.
