Patient sedation during flexible bronchoscopy is variable depending on the experience and preference of the bronchoscopist. Some authors1 have suggested that sedation is not required for bronchoscopy. In support of this approach has been the argument that up to half of the major complications of bronchoscopy are sedation related. In general, however, most bronchoscopists use some form of sedation to alleviate patient anxiety, pain, cough, and dyspnea. Improving patient comfort and providing some degree of amnesia by using sedation likely increases the patient willingness to undergo additional bronchoscopic procedures.2,3 The ability to adequately and safely perform advanced diagnostic and therapeutic bronchoscopies is likely improved with sedation.
