About this study

In humans and animals, circadian rhythm sleep cycle is an important function to maintain and regulate basic physiological homeostasis, such as cognitive function, glucose metabolism, memory consolidation, immune function and growth hormone secretion. The induction of general anesthesia leads to a state of reduced responsiveness, which is often described by anesthesiologists and patients as "sleep". However, previous studies have shown that in the case of patients under general anesthesia, besides surgery trauma and general anesthetics may change sleep function and sleep cycle perioperatively, the postoperative complications such as pain, nausea and vomitting etc after general anesthesia may also reduce postoperative sleep quality.Meanwhile, there is a mixed literature linking sleep and markers of systemic inflammation that greater sleep disturbances were associated with higher levels of circulating IL-6 and CRP but not TNF-α. And the effects of inflammatory cytokines may also cause changes in sleep patterns. Flurbiprofen axetil is a new non-steroidal anti infection analgesic(NSAIDs), which is widely used for analgesia to reduce the dose of opioids. It not only has a high affnity for infammatory tissues to achieve targeted drug therapy and prolonged duration of action, but causes analgesia effect through decreasing the biological production of prostaglandins, reducing the reactivity of peripheral nerves to endogenous infammatory factors, and inhibiting the sensitization of central as well as peripheral nervous systems.Furthermore, it could also inhibite the occurrence of adverse reactions, such as declined sleep quality, respiratory depression, nausea and vomiting. Preemptive analgesia is an analgesic intervention that begins before surgery to prevent the nervous system from becoming sensitive to subsequent stimuli that may aggravate pain. A large number of experimental studies have shown that the use of local anesthetics and/or analgesics in advance can prevent central nervous system hyperplasia, thereby reducing postoperative pain. The aim of our study was to investigate the effect of preemptive analgesic with flurbiprofen axetil on postoperative pain, inflammatory markers and sleep quality among patients under general anesthesia. We hypothesized that use flurbiprofen axetil preoperatively would effectively relieve postoperative pain, inhibite inflammtory reaction and improve postoperative sleep quality.

What is being measured

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

  1. Postoperative 24 hours pain score

    Use VAS to evaluated postoperative pain score

    Measured: 24 hours after surgery

  2. perioperative inflammatory markers

    The inflammtory markers such as system inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR) were recorded before and after surgery. SII= platelet count × neutrophil count/lymphocyte count, NLR= neutrophil count/lymphocyte count, MLR= monocyte count/lymphocyte count.

    Measured: the day before surgery

  3. perioperative inflammatory markers

    The inflammtory markers such as system inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) were recorded before and after surgery. SII= platelet count × neutrophil count/lymphocyte count, NLR= neutrophil count/lymphocyte count, MLR= monocyte count/lymphocyte count.

    Measured: first day after surgery

  4. perioperative inflammatory markers

    The inflammtory markers such as system inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR) were recorded before and after surgery. SII= platelet count × neutrophil count/lymphocyte count, NLR= neutrophil count/lymphocyte count, MLR= monocyte count/lymphocyte count.

    Measured: third day after surgery

Secondary outcomes (4)
  1. preoperative sleep quality

    evaluate postoperative sleep quality at the first night before surgery

    Measured: the first night before surgery

  2. postoperative sleep quality

    evaluate postoperative sleep quality at the first night after surgery

    Measured: the first night after surgery

  3. postoperative sleep quality

    evaluate postoperative sleep quality at the third night after surgery

    Measured: the third night after surgery

  4. postoperative adverse effects

    evaluate postoperative adverse effects

    Measured: 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Flurbiprofen axetil preoperatively and Flurbiprofen axetil postoperatively in people with Flurbiprofen Axetil and Preemptive Analgesia, run by Beijing Friendship 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 1 inclusion and 5 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 Jul 2025. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 24 hours pain score (time frame: 24 hours after surgery). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04611763, which also lists 1 linked publication.

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 Jul 2025.
