The Essential cTBNA Bronchoscopist contains thirty multiple choice question/answer sets and a twelve question post-test pertaining to conventional transbronchial needle aspiration. This minimally invasive procedure is used to diagnose airway disorders and diseases affecting the mediastinum. These include Sarcoidosis, lung cancer, tuberculosis, lymphoma, and other disorders such as infections or other tumors that spread to the lymph glands or are adjacent to the tracheobronchial tree. Topics include indications, technical pearls, potential complications, expected results, patient, operator and equipment safety, mediastinal and airway anatomy, and how cTBNA is used alongside other bronchoscopic procedures such as biopsy, bronchoalveolar lavage, brushing, and EBUS-guided TBNA. This seventy page volume is the third in the Essential Bronchoscopist series of bronchoscopy training manuals offered by Bronchoscopy International, a transnational group of medical educators dedicated to an "education without borders."
