Use of Endobronchial Ultrasound Scope (EBUS) Transducer to Identify Pneumothorax-A Feasibility Study

Endobronchial ultrasound (EBUS) is a technique that uses ultrasound along with bronchoscope to visualize airway wall and structures adjacent to it. Pneumothorax is a known complication from EBUS procedure. To rule out a Pneumothorax after the procedure, a Chest -X-ray is usually done. Point-of-care sonography has emerged as an invaluable tool in the assessment of patients with both traumatic and non-traumatic dyspnea. Multiple studies involving bedside ultrasound has shown that a pneumothorax can easily be ruled out if pleural sliding sign or B lines are visualized on lung ultrasonography; the accuracy of lung ultrasound in ruling out pneumothorax approach computed tomography and exceed plain radiography. Preforming a lung ultrasound using the EBUS bronchoscope tip as a way to rule out pneumothorax has never been described previously. If this is possible it will obviate the need of getting a Chest -X-ray and decrease the dose of radiation that the patient is exposed to. In this study we will demonstrate that the feasibility of using the transducer of the EBUS Bronchoscope to perform bedside lung ultrasound to rule out pneumothorax.
