Study Description

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.

Condition or Disease Intervention/Treatment Phase

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Ultrasonography

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.

Diagnostic Test: Lung ultrasonography by experienced anaesthesiologist
Use ultrasound image of lung at upper and lower lobe to detect lung collapse and compare grading of lung collapse by surgeon as gold standard

Active Comparator: Fiberoptic bronchoscopy

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.

Diagnostic Test: Fiberoptic bronchoscopy for double lumen tube's position
Use fiberoptic bronchoscope via double lumen tube to detect optimum position of double lumen tube and record grading of lung collapse by surgeon as gold standard

Outcome Measures

Primary Outcome Measures

  1. 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

  1. 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)

  2. 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
