Correct Placement and Rapid Confirmation of Double Lumen Tube and Bronchial Blocker Using Fluoroscopic Guidance

Double Lumen Tube (DLT) and Bronchial Blocker (BB) are frequently used to provide One Lung Ventilation (OLV) in major thoraco-abdominal and spine surgeries. With advanced surgeries like Video Assisted Thoracic Surgeries (VATS), rapid and accurate placement of the DLT/Bronchial Blocker is necessary. Clinical examination includes inspection of chest movements and auscultation of breath sounds. These clinical methods remain important means of accurate placement of DLT/Bronchial blocker as a first confirmation test. However, these methods are subjective, and variability exists between individuals who are very common, and it fails to correctly identify the placement in 37% of the patients and requires repositioning by bronchoscopy.
