About this study

BACKGROUND: The aim of this study is to evaluate the confirmation of double lumen tube placement with thoracic Ultrasound (USG) in thorax surgery operations with one lung ventilation.

METHODS: In this prospective and observational study, 130 patients aged between 18-65 years in ASA (American Society of Anesthesiology) I-III risk class who will undergo thoracic surgery with the application of single-lung ventilation were included in the study. A double-lumen endobronchial tube was placed in the patients blindly. One-lung ventilation (OLV) was confirmed by thoracic USG by the anesthesiologist. The patient's demographic data, rapid clinical evaluation and USG data results, and intraoperative surgeon satisfaction were recorded.

Read the detailed description

This prospective observational study was carried out in the Department of Anesthesiology and Reanimation, with the permission of the Ethics Committee of Dokuz Eylul University Medical Faculty Hospital (Ethics Committee Decision No:2021/17-04). Between 01.07.2021 and 01.12.2021, cases requiring single-lung ventilation by thoracic surgery in the operating room of Dokuz Eylul University Faculty of Medicine were included in the study.

Over 18 years old, patients who need OLV and undergoing elective surgery was determined as inclusion criteria. Furthermore patients did not want to participate in the study, with a narrowed trachea and/or a narrowed main bronchus that does not allow DLT placement, with endobronchial lesion in the main bronchus, with subcutaneous emphysema, having a chest tube due to pneumothorax, with pleural effusion, having a history of pleurodesis, bullous lung, patients with a history of tracheostomy and patients who will undergo emergency surgery determined as exclusion criteria for the study.

On the day of surgery, all patients were premedicated after a 20 G cannula was placed on the back of the hand before they were taken to the operating room. Routine anesthesia induction was performed after preoxygenation with 100% O2 for 5 minutes by monitoring 3-lead electrocardiography, peripheral oxygen saturation and noninvasive blood pressure in the patients who were taken to the operating room. After anesthesia induction, patients underwent double lumen tube intubation and after confirming single lung ventilation with thoracic USG (GE Healthcare LOGIQ e), tube location was confirmed by fiberoptic bronchoscopy (FOB) and clinical evaluation and recorded. Slip sign on USG was evaluated with M-mode imaging in the right and left lower quadrants of the thorax at the level of the costophrenic angles. When the bronchial lumen was clamped, the tube was considered to be positioned correctly if the left shift sign was selectively lost.

Age, gender, body mass index (BMI), AmericanSociety of Anesthesiologists score, co-morbidities (Hypertension, diabetes mellitus, malignancy, chronic obstructive pulmonary disease) duration of surgery, clinical and FOB evaluation results of the patients included in the study, in the supine position and in the lateral position during the intraoperative period. The determined DLT malpositions and the manipulations performed to correct them and the results of the evaluation with the thorax USG method, as well as the intraoperative surgeon satisfaction were recorded by the doctor who followed the case.

Questions about this trial

What is this clinical trial studying?

An observational study of One Lung Ventilation, run by Dokuz Eylul 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 2 inclusion and 10 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 3 Oct 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?

Thoracic USG sensitive and specificity values (time frame: immediatelay after the Replacement of double lumen ETT). 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 NCT06064773, 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 3 Oct 2023.
