About this study

Official title: Effect of Lateral Positioning on Bronchial Cuff Pressure of Left-sided Double-lumen Endotracheal Tube During Thoracic Surgery: a Prospective Observational Study

The investigators evaluate the effect of postural change on the bronchial cuff pressure (BCP) of double-lumen endotracheal tube (DLT) in patients undergoing thoracic surgery, by observing the pressure of the bronchial cuff before and after lateral decubitus positioning.

Read the detailed description

It is essential to maintain proper cuff pressure in the endotracheal tube (ETT) when placing the ETT in the trachea in patients undergoing general anesthesia. Most of the literature recommend maintaining a pressure of 20-30 cmH2O to prevent cuff-related complications such as micro-aspiration or airway trauma. Proper pressure is also important for DLTs used in thoracic surgery. Furthermore, the cuff pressure of the ETT can change during the patient's positional changes. All things considered, we hypothesized that the change from supine to lateral decubitus position, which is essential for thoracic surgery would affect the BCP of the DLT.

What participants receive

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

  • Lateral decubitus positioningBehavioural

    After the DLT intubation, the patient is placed in lateral decubitus position

  • Cuff-manometerDevice

    The pressure of the bronchial cuff should be measured with cuff-manometer in supine position, and then measurement should be repeated after lateral positioning.

What is being measured

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

  1. Change of the maximum bronchial cuff pressure (BCP) which does not exceed 40 cmH2O with no air leak from supine to lateral decubitus position

    A cuff-manometer will be connected to the valve of the pilot balloon of bronchial cuff via a three-way stopcock. And then, the BCP will be assessed, while inflating the cuff with air in 0.5 ml increments from 0 to 3.0 ml. If the BCP exceeds 40 cmH2O during expansion by increasing 0.5 ml from 0 to 3.0 ml, we will stop inflating the bronchial cuff with air and record the bronchial cuff volume (BCV) and BCP up to the last numerical value. During the pressure measurement, air leak or seal around the bronchial cuff will be assessed at each time point when inflating the cuff in 0.5 ml increments.

    Measured: 1. In supine position, 2 minutes after the completion of confirming the double-lumen endotracheal tube (DLT) position via fiberoptic bronchoscope (FOB) 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

Secondary outcomes (2)
  1. The incidence of the patients whose maximum BCP exceed 40 cmH2O after lateral positioning

    Measured: 1. In supine position, 2 minutes after the completion of confirming the DLT position via FOB 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

  2. The minimum BCV that is the smallest bronchial cuff volume without air leakage

    Measured: 1. In supine position, 2 minutes after the completion of confirming the DLT position via FOB 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

Questions about this trial

What is this clinical trial studying?

An observational study of Lung Cancer and Pneumothorax, run by Daegu Catholic University Medical Center 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 2 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 6 Aug 2020. 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?

Change of the maximum bronchial cuff pressure (BCP) which does not exceed 40 cmH2O with no air leak from supine to lateral decubitus position (time frame: 1. In supine position, 2 minutes after the completion of confirming the double-lumen endotracheal tube (DLT) position via fiberoptic bronchoscope (FOB) 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB). 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 NCT03656406, which also lists 4 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 6 Aug 2020.
