Background: Single Lung Ventilation or One-Lung ventilation (OLV) is often necessary for thoracic surgeries involving lung, esophagus, aorta, or mediastinum. Various airway devices, like DLTs and bronchus blockers, facilitate one lung ventilation, with DLTs being the most widely used globally. However, DLT intubation has drawbacks, prompting the development of bronchus blockers like EZ-Blocker. The EZ-Blocker features a Y-shaped design with cuffs on both ends, simplifying placement and reducing complications. Limited trials have compared EZ-Blocker to DLT or other blockers. This study aims to evaluate EZ-Blocker against DLT for Lung Isolation Surgeries in Indian settings, filling a gap in existing research. Methods: 46 adult patients who had to undergo elective thoracic surgery requiring thoracotomy and SLV were included in this prospective, randomized, single-blinded study with blinding of the outcome assessor. Patients were randomly assigned to one of the 2 groups: DLT or EZ Blocker group. The time for placement of device, which included time for device preparation and time for placement of the device, was recorded along with the number of repositioning after positioning of patient. After the surgery, the surgeon rated the quality of the collapse of lung and patient's sore throat, and hoarseness were recorded. Results: The time for placement of DLT (170.47 sec) was significantly faster than EZ Blocker (230.7 sec), as was the time for successful intubation and time for preparation for DLT faster than EZ. Number of repositioning required were more in the EZ Blocker group (52.2%) compared to DLT Group (43.5%). Quality of lung collapse was rated better for DLT (60.9%) than EZ Blocker (39.2%) whereas post-operative complications of intubation were more in the DLT group owing to its larger external diameter. Conclusion: EZ Blocker is a reliable option for single lung ventilation (SLV) during thoracic surgery, particularly in patients with limited mouth opening. Despite having fewer post-operative complications like sore throat and hoarseness compared to the DLT, the DLT outperforms the EZ Blocker in terms of preparation time, placement time, number of repositioning needed, and surgeon satisfaction score. Therefore, for lung isolation surgeries, the DLT is the preferred choice for achieving optimal one lung ventilation (OLV). [ABSTRACT FROM AUTHOR] |
