Inclusion Criteria
patients (age range 16 to 77 yr; American Society of Anesthesiologists physical status I-III) undergoing a left - sided thoracic procedure for which one lung ventilation is required
Exclusion Criteria
1. Patients who presented with an intraluminal lesion of the right bronchus or with very distorted anatomy of the tracheobronchial tree on a chest radiograph
2. Patients with a history of prior thoracotomy, pleural effusion on a chest radiograph, thoracic aneurysm or the possibility of pleural adhesions (such as tuberculosis or previous chest tube insertion)
Study & Design

- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method proportion of the malposition of the endotracheal tube (herniation of the bronchail balloon, poor lung isolation, lack of alignment between the slot and the RUL origin)
- Secondary Outcome Measures
Name Time Method incidence of hypercapnea (EtCO2 > 45 mmHg), ;number of times for each patient that the FOB was required for assurance of proper positioning during the operation;number of malpositions after initial tube placement;incidence of hypoxemia (SpO2 < 90%);time required for positioning of the DLTs. The time began when the tube passed the carina and ended when satisfactory placement was demonstrated by the FOB (supine position);incidence of high airway pressure (Peak inspiratory pressure > 35 cm H2O)
