Topical anesthesia with 5 mL of 1% lidocaine jelly is applied to the nostril being used for bronchoscopy; 2-mL aliquots of 1% lidocaine are then applied at the level of the vocal cords until the patient is comfortable with minimal cough. Additional 2-mL aliquots of lidocaine can be applied to the tracheobronchial tree. It is recommended to use a 1% concentration of lidocaine to limit the risk of lidocaine toxicity.
