Interventions

Intervention1: Bronchial Blocker: Seventy adult patients (ASA I III) requiring OLV will be randomized into two groups (35 per group) to receive either the EZ-Blocker or Fuji Uniblocker. After inductio

Eligibility

Inclusion criteria

Inclusion criteria: American Society of Anesthesiologists (ASA) physical status I-III, scheduled for elective procedure requiring one lung ventilation.

Exclusion criteria

Exclusion criteria: Pregnant women Patients with significant tracheal or bronchial abnormalities as evidenced by High Resolution Computed Tomography (HRCT) findings (e.g., tumor, stenosis, tracheomalacia)

Design outcomes

Primary

Measure	Time frame
to compare quality of long collapse using lung collapse as rated by operating surgeonTimepoint: assessing lung collapse 10 and 20 minutes after initiating one lung ventilation	—

Secondary

Measure	Time frame
To compare time required to achieve successful lung isolation between devices To assess number of attempts required for successful device placement To determine number of malpositions & repositioning attempts intraoperativelyTimepoint: Time from the insertion of Brochial Blocker till its visualisation in the fiberoptic (noted in minutes & seconds) Number of attempts recored as 1,2 or so on for number of attempts during device placement Measured in the intraoperative period	—
