Overview
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.

Eligibility Criteria
Inclusion Criteria
- •Adult patients, age ≥18 years old
- •American Society of Anesthesiologists(ASA) physical status classification I - III
- •Scheduled for elective thoracic surgery which requires One lung ventilation(OLV) with Left-sided double lumen tube
Exclusion Criteria
- •Anticipated difficult intubation or with the tracheostomy tube
- •Patient with pneumothorax, pleural effusion, emphysema or past history of pleurodesis
- •Patient with deranges pulmonary function test (out of forced expiration volume in 1 s, total lung capacity, forced vital capacity \<50% of the predicted values)
- •The patient refuses to participate.
Outcomes
Primary Outcomes
Number of Patients of Lung Collapse in Ultrasonography and Fiberoptic Bronchoscopy
Time Frame: 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 Outcomes
- Timing to Detect Lung Collapse(30 minutes)
- Accuracy of Detection of Lung Collapse in Ultrasonography Method in Cardiovascular and Thoracic Anesthesia Fellow(30 minutes)
