Endobronchial ultrasound (EBUS) is ultrasound combined with bronchoscopy. It is used to obtain images in and around the bronchial tree or the lungs. EBUS allows the physician to see beyond the bronchial wall, to the diseased tissue, lymph nodes and/or lesions outside of the bronchial airways. Therefore, it can be used in the diagnosis of lung cancer, infections and other diseases that cause enlarged lymph nodes in the chest, and to evaluate lesions which cause airway invasion. The greatest benefit of using EBUS for evaluating the central airway is that the patient can potentially avoid having to undergo a more invasive surgical procedure and can eliminate the need for additional phases of testing.
How to Prepare for your EBUS
Preoperative services will contact you with instructions 1 to 2 days before your procedure. Check-in at Same Day Surgery which is located on the second floor of Wentworth Douglass Hospital at the South Entrance. No food after midnight the night before. You should arrive 1 1/2 hours prior to your procedure. Your health care provider may tell you to avoid aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, or blood thinners such as warfarin for a period of time before the procedure. Always check with your health care provider before changing or stopping any medications.
What to Expect
Shortly before the procedure a small intravenous (IV) will be placed into your hand or forearm. EBUS is performed under local anesthesia therefore, you will be asleep for the entire procedure. The physician will first inspect your airways using a bronchoscope.
After your EBUS
You will be watched in a recovery room for a short length of time. It will take several hours before you will be able swallow liquids. Your throat may be slightly sore. You will need someone to drive you home and stay with you overnight.
