A Comparison of Positional Stability: the EZ-blocker Versus Left Sided Double Lumen Tube in Adult Patients for Thoracic Surgery
In Brief
A clinical study evaluating EZ-Blocker and DLT for Thoracic Injuries. Completed, enrolled 163 participants across 1 site.
Detailed Summary
The objective of this study is to evaluate the positional stability and quality of lung isolation provided by the EZ-blocker compared to a DLT for both right and left sided thoracic surgery. An additional objective will be to assess time to placement of both devices and other significant clinical differences between these two approaches to placement of the bronchial blocker (BB) including airway injury and post-operatives sore throat, post-operative hoarseness, Additionally we would like to examine the preoperative high resolution CT imaging data to determine if there are anatomic landmarks that may potentially inform the appropriateness or inappropriateness of choosing an EZ-blocker or left sided DLT.
Study Details
Timeline
Interventions
The EZ-Blocker essentially functions as a bronchial blocker with a 7-Fr shaft with two separate occlusive balloons coming off this shaft in a "Y" configuration designed to rest on the carina. Once anchored in place the operator can choose to inflate one of the two occlusive balloons to isolate one main stem bronchus or the other. According to the manufactures recommendations the EZ-blocker is placed through a Y-piece adaptor included with the blocker kit. A flexible fiberoptic bronchoscope (FFB) is placed in a separate limb of this Y-piece and this fed through along side the EZ-blocker to visualize and confirm placement of the of the BB. The balloon is then inflated typically under direct vision to occlude that bronchus thus isolating that lung hopefully achieving full lung isolation.
A Double Lumen Tube (DLT) is made of two small-lumen endotracheal tubes of unequal length fixed side by side. The shorter tube ends in the trachea while the longer tube is placed in either the right or left bronchus to ventilate the right or left lung.
