About this study

Official title: Comparison of Intravenous Anesthetics and Volatile Anesthetics on Postoperative Cognitive Dysfunction of Patients Undergoing Endovascular Repair of Aortic Aneurysm and Endovascular Treatment of Arteriosclerosis Obliterans of Lower Extremities.

Endovascular repair of aortic aneurysm and endovascular treatment of arteriosclerosis obliterans of lower extremities are two kinds of common surgeries in the investigators' hospital. The effects of anesthetic agents on postoperative outcome, especially cognitive function, are not clear. In this study investigators propose to measure postoperative cognitive function and other outcome of patients who are undergoing these two kinds of surgeries, and try to identify whether there is an association between different kinds of anesthetics and postoperative outcome. Investigators will also observe whether changes in plasma levels of VEGF, TGF-1, TNF-α, IL-1β, and IL-6, are associated with postoperative delirium or cognitive change.

What participants receive

Study groupRoleWhat they receive
Sevoflurane & remifentanilExperimentalsevoflurane at 0.5 to 1.5 minimum alveolar concentrations plus remifentanil (0.1 - 0.5 µg/kg/min) during the surgery.
Receives: Drug: Sevoflurane; Drug: Remifentanil
propofol & remifentanilActive comparatorpropofol (50 - 150 µg/kg/min) plus remifentanil (0.1 - 0.5 µg/kg/min) during the surgery.
Receives: Drug: Propofol; Drug: Remifentanil

What is being measured

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

  1. Number of patients with postoperative cognitive dysfunction

    Measured: 7 days after surgery

Secondary outcomes (2)
  1. Number of patients with postoperative cognitive dysfunction

    Measured: 3 months after surgery

  2. Changes in plasma levels of VEGF, TGF-1, TNF-α, IL-1β, and IL-6 (a composite outcome measure)

    Measured: 3 days after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sevoflurane, Propofol and Remifentanil in people with Endovascular Repair of Aortic Aneurysm and Endovascular Treatment of Arteriosclerosis Obliterans of Lower Extremities, run by Tao Zhang 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 2 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 12 Jun 2018. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Number of patients with postoperative cognitive dysfunction (time frame: 7 days after surgery). 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 12 Jun 2018.
