About this study

Official title: The Effect of Desfluran Administered in General Anesthesia On Global Dna Methylation

The purpose of this study is to demonstrate the molecular effect of desflurane on DNA by measuring the global DNA methylation level in patients under going lumbar spinal stenosis surgery under general anesthesia.

Read the detailed description

Forty patients scheduled for lumbar spinal surgery will include in the study. Peripheral venous blood samples will collect prior to the induction of anesthesia (T1) and after 120 minutes (T2). Anesthesia will maintaine with 40%-60% O2-air mixture and 6% desflurane. DNA will obtain from blood samples with the help of DNA isolation kit and global DNA methylation analysis will perform by ELISA method.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DesfluraneDrug

    Peripheral venous blood samplesof patients will collected at two time points as follows: before the premedication and the induction of anesthesia (T₁): 120 minutes after the beginning of anesthesia (T₂). Anesthesia maintenance will be provided with 40% O₂ and minimum alveolar concentration (MAC) in 60% air with 6% desflurane. DNA will be obtained from blood samples with the help of DNA isolation kit, and global DNA methylation analysis will performed by ELISA method.

Receives: Drug: Desflurane

What is being measured

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

  1. Global DNA methylation change 5 minutes before and 120 minutes after anesthesia induction in peripheral blood mononuclear cells

    The global DNA methylation level will be measured 5 minutes before and 120 minutes after anesthesia induction.

    Measured: 5 minutes before induction of anesthesia ,120 minutes after the beginning of anesthesia

Questions about this trial

What is this clinical trial studying?

An observational study of DNA Damage, run by Muğla Sıtkı Koçman University at 1 site in Turkey (Türkiye).

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 4 inclusion and 9 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 15 Mar 2023. 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 Turkey (Türkiye). 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?

Global DNA methylation change 5 minutes before and 120 minutes after anesthesia induction in peripheral blood mononuclear cells (time frame: 5 minutes before induction of anesthesia ,120 minutes after the beginning of anesthesia). 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 NCT05111717, which also lists 3 linked publications.

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 15 Mar 2023.
