Lung Ultrasonography vs Fiberoptic Bronchoscopy for Aiding Lung Collapse in Patient Using Double Lumen Tube

Not Applicable
Completed
Conditions
Ultrasonography
Thoracic Surgery
Lung Diseases
One Lung Ventilation
Lung Collapse
Fiberoptic Bronchoscopy
Interventions
Diagnostic Test: Lung ultrasonography by experienced anaesthesiologist
Diagnostic Test: Fiberoptic bronchoscopy for double lumen tube's position
Registration Number
NCT03314519
Lead Sponsor
Mahidol University
Brief Summary

The study contains the result from a comparison of diagnostic outcomes about lung collapse by using lung ultrasonography as a new diagnostic test compares to fiberoptic bronchoscopy as the standard test.

Detailed Description

The study contains the result from a comparison of diagnostic outcomes about lung collapse by using lung ultrasonography as a new diagnostic test compares to fiberoptic bronchoscopy as a standard test. Both of them detect lung collapse reported as surgical grading lung collapse by the thoracic surgeons. The protocol was performed in a randomized controlled trial whether the subject was allocated to the ultrasonography group or the fiberoptic bronchoscopy group.

GroupInterventionDescription
UltrasonographyLung ultrasonography by experienced anaesthesiologistPatients in this group receive lung ultrasonography to detect lung collapse after insert double lumen tube and finally compare lung collapse by the surgeon's visual grading scale of lung collapse when entering pleural cavity.
Fiberoptic bronchoscopyFiberoptic bronchoscopy for double lumen tube's positionPatients in this group receive fiberoptic bronchoscope to detect lung collapse after inserting a double lumen tube and finally compare lung collapse by the surgeon's visual grading scale of lung collapse when entering the pleural cavity.
Primary Outcome Measures
NameTimeMethod
Number of Patients of Lung Collapse in Ultrasonography and Fiberoptic Bronchoscopy30 minutes

Compare number of patients with lung collapse detected by ultrasonography and fiberoptic bronchoscopy in patient with double lumen tube by report as specificity and sensitivity of detection of lung collapse by compare to visual grading of lung collapse by surgeon

Secondary Outcome Measures
NameTimeMethod
Timing to Detect Lung Collapse30 minutes

Time point from evaluation of lung collapse by each test to time point of grading lung collapse by gold standard( visual grading of lung collapse by surgeon)

Accuracy of Detection of Lung Collapse in Ultrasonography Method in Cardiovascular and Thoracic Anesthesia Fellow30 minutes

Accuracy of detection of lung collapse in thoracic patient with lung ultrasonography in cardiac anaesthesiologist after training lung ultrasonography
