About

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.

Full 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.

Enrollment: 200 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

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.

Trial design

Primary purpose: Diagnostic

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

200 participants in 2 patient groups

Ultrasonography

Experimental group

Description:

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.

Treatment:

Diagnostic Test: Lung ultrasonography by experienced anaesthesiologist

Fiberoptic bronchoscopy

Active Comparator group

Description:

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.

Treatment:

Diagnostic Test: Fiberoptic bronchoscopy for double lumen tube's position
