1.Patients who are deemed suitable for both extraluminal as well as intraluminal placement of BB by a thoracic anaesthetist. This would typically include patients in whom a cuffed single lumen endotracheal tube of size 7.5 or above is considered appropriate i.e. most male patients and female patients with height above 155 cm
2.Patients in whom a bronchial blocker with a fixed angle tip is chosen for lung isolation e.g. Coopdech blocker, Tappa blocker or Fuji blocker
1.Patients with risk of cross contamination of lung with blood or infected secretions, or those with bronchopleural fistula
2.Patients in whom EZ or Arndt blocker is used for lung isolation
3.Patients with abnormal tracheobronchial anatomy detected on radiological imaging or flexible bronchoscopy
4.Patients with an anticipated difficult airway
5.Patients with unanticipated difficult airway e.g. those requiring more than 3 attempts at endotracheal intubation, those requiring rescue measures to maintain oxygenation, etc
6.Patients belonging to ASA III physical status
7.Patients at high risk of regurgitation and aspiration
8.Patients in whom a 7F BB is unable to achieve a seal (and therefore isolation)
9.Patients who cannot give valid consent
10.Pregnancy

Name Time Method 1.Number of patients in whom there was failure to place BB in each group <br/ ><br>2.Total number of episodes of intraoperative repositionings in each group. <br/ ><br>3.Average time taken for insertion of BB i.e. time from insertion of bronchoscope to optimum placement in each group <br/ ><br>4.Average time taken per intraoperative repositioning in each group <br/ ><br>5.Subjective ease of insertion as reported by the attending anaesthetist <br/ ><br>6.Quality of lung collapse at 5, 10 and 30 minutes after opening of thorax <br/ ><br>Timepoint: 1.
