Topical Anesthesia / Bronchoscopy

Topical Nasopharyngeal Anesthesia in Outpatient Bronchoscopy

Patients included in the first half of the study (topical anesthesia with the Laryngeal atomizer) and with need for another bronchoscopy in the second half of the study (topical anesthesia with the Intranasal Mucosal Atomization Device) will be asked to repeat the questionnaire after the second bronchoscopy to allow in-patient comparison.
