- Diagnostic Test: Lung ultrasonography by experienced anaesthesiologistDiagnostic 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.

Group Intervention Description Ultrasonography Lung ultrasonography by experienced anaesthesiologist Patients 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 bronchoscopy Fiberoptic bronchoscopy for double lumen tube's position Patients 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
Name Time Method Number of Patients of Lung Collapse in Ultrasonography and Fiberoptic Bronchoscopy 30 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
Name Time Method Timing to Detect Lung Collapse 30 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 Fellow 30 minutes Accuracy of detection of lung collapse in thoracic patient with lung ultrasonography in cardiac anaesthesiologist after training lung ultrasonography
