About this study

The purpose of this study is to investigate a performance of initial positioning of left sided double lumen endobronchial tubes using peak inspiratory pressures difference between two lungs.

Read the detailed description

If both lungs have relatively equal volumes and the double lumen tube is in a satisfactory position, peak inspiratory pressure between two lungs is similar or equal when each lumen is sequentially clamped while ventilating each lung with the same tidal volume. We are going to investigate a performance of this method by fiberoptic bronchoscopy view and depth of double lumen tube, and compare with an conventional auscultation method.

What is being measured

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

  1. Fiberoptic bronchoscopy view

    1. aucsultation under manual ventilation -> fiberopric bronchoscopy view check
    2. peak inspiratory pressure difference under mechanical ventilation -> fiberoptic bronchoscopy view check

    Measured: within 5 min after intubation

Secondary outcomes (1)
  1. depth of double lumen tube

    1. aucsultation under manual ventilation -> A depth of DLT (incisor)
    2. peak inspiratory pressure difference under mechanical ventilation -> A depth of DLT (incisor)

    Measured: within 5 min after checking fiberopitics

Questions about this trial

What is this clinical trial studying?

A study testing Pressure difference in people with Thoracic Surgery, run by Yonsei University 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 3 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 10 Jan 2019. 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?

Fiberoptic bronchoscopy view (time frame: within 5 min after intubation). 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 NCT01533012, 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 10 Jan 2019.
