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

Mahidol University200 enrolled

Overview

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.

Interventions

Lung ultrasonography by experienced anaesthesiologistDIAGNOSTIC_TEST

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

Fiberoptic bronchoscopy for double lumen tube's positionDIAGNOSTIC_TEST

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

Outcomes

Primary Outcomes

Number of Patients of Lung Collapse in Ultrasonography and Fiberoptic Bronchoscopy

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

Time frame: 30 minutes

Secondary Outcomes

Timing to Detect Lung Collapse

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)

Time frame: 30 minutes

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

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

Time frame: 30 minutes
