About this study
Official title: The Different Analgesic Potency of Sevoflurane and Desflurane at Equi-minimum Alveolar Concentration
The aim of this clinical trial is to evaluate the difference of analgesic potency of sevoflurane and desflurane at equi-minimum alveolar concentration using a surgical pleth index.
Read the detailed description
Volatile anesthetics vary in their relative hypnotic potencies. Recent studies demonstrated that equi-minimum alveolar concentration of various volatile anesthetics produced different EEG-derived indices such as bispectral index. However, there was no controlled study that demonstrates the difference of analgesic potency. The aim of this clinical trial is to evaluate the difference of analgesic potency of sevoflurane and desflurane at equi-minimum alveolar concentration using a surgical pleth index.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SevofluraneDrug
Also called SEVO
Anesthesia was maintained with sevoflurane in patients undergoing arthroscopic shoulder surgery under general anesthesia and interscalene brachial plexus block.
DesfluraneDrug
Also called DES
Anesthesia was maintained with desflurane in patients undergoing arthroscopic shoulder surgery under general anesthesia and interscalene brachial plexus block.
| Study group | Role | What they receive |
|---|---|---|
| Sevoflurane | Experimental | Anesthesia was maintained with sevoflurane. Receives: Drug: Sevoflurane |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sevoflurane and Desflurane in people with Orthopedic Disorders, run by Kangbuk Samsung Hospital at 1 site in South Korea.
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 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 8 Nov 2017. 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 South Korea. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
Analgesic potency of volatile anesthetics (time frame: the first 60 min of maintaining a steady state 1 MAC of volatile agents). 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 8 Nov 2017.
