About this study

One-lung ventilation during thoracic surgery may affect systemic oxygenation and peripheral microcirculation by hypoxic pulmonary vasoconstriction. Both intravenous and inhalational anesthetics can be used during one-lung ventilation. However, there is still a controversy which anesthetic would be more appropriate during one-lung ventilation in the perspective of oxygenation and microcirculation. The investigators hypothesized that intravenous and inhalational anesthetics may affect oxygenation and microcirculation differently during one-lung ventilation.

Read the detailed description

Patients undergoing thoracic surgery including one-lung ventilation will be randomized to receive intravenous (propofol) or inhalational (desflurane) anesthetic.

Systemic oxygenation can be evaluated by measuring partial pressure of oxygen in arterial blood analysis. Microcirculatory parameters can be obtained from vascular occlusion test. Among those parameters, recovery slope during vascular occlusion test is known to reflect recruitment of microvasculature in response to hypoxic or ischemic insult. In this study, we will compare arterial partial pressure of oxygen and recovery slope during one-lung ventilation between propofol and desflurane group.

What participants receive

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

  • propofolDrug

    Also called propofol (Fresofol(R)2 MCT 2%, Fresenius Kabi)

    Patients are randomized to receive intravenous anesthetic (propofol) or inhalational anesthetic (desflurane) as a maintenance anesthetic.

  • desfluraneDrug

    Also called desflurane (Suprane(R), Baxter Healthcare)

    Patients are randomized to receive intravenous anesthetic (propofol) or inhalational anesthetic (desflurane) as a maintenance anesthetic.

Study groups in NCT02191371
Study groupRoleWhat they receive
propofolExperimentalPropofol is used as a maintenance anesthetic to patients in the propofol group. Intervention: propofol infusion by target-controlled infusion for maintaining anesthesia propofol (Fresofol MCT 2%) target effect site concentration: 4~5 mcg/ml, during general anesthesia
Receives: Drug: propofol
desfluraneExperimentalDesflurane is used as a maintenance anesthetic to patients in the desflurane group. Intervention: Desflurane administration for maintaining anesthesia desflurane (Suprane) inhalation as 6~8 vol% during general anesthesia
Receives: Drug: desflurane

What is being measured

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

  1. arterial partial pressure of oxygen

    Primary outcome is arterial partial pressure of oxygen 30 min after one-lung ventilation during thoracic surgery in propofol and desflurane groups.

    Measured: 30 min after one-lung ventilation

Secondary outcomes (1)
  1. recovery slope

    Secondary outcome is recovery slope measured by vascular occlusion test 30 min after one-lung ventilation during thoracic surgery in propofol and desflurane groups.

    Measured: 30 min after one-lung ventilation

Questions about this trial

What is this clinical trial studying?

A study testing propofol and desflurane in people with Mechanical Ventilation Complication, run by Seoul National University 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 1 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 13 Oct 2016. 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.

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?

arterial partial pressure of oxygen (time frame: 30 min after one-lung ventilation). 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 NCT02191371, 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 13 Oct 2016.
