The goal of this randomized control trial is to evaluate the effectiveness and safety of using a spray nozzle, compared to the conventional method, for topical anesthesia by the spray-as-you-go technique in reducing cough frequency, improving cough, discomfort, tolerance, satisfaction, reducing the dosage of lidocaine consumption of patients during flexible bronchoscopy.

Cough rate
The bronchoscopy procedure will be audio-taped throughout and cough counting will be recorded by an investigator blinded to the patient information and grouping. The cough rate will be calculated as total cough counts divided by procedure time in minute.
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
Procedure time
The duration (minute) of the bronchoscopic procedure
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
Lidocaine dosage
Total lidocaine doses dispensed during the bronchoscopic procedure
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
Patient tolerance
Using a visual analogue scale from 0 to 10 to indicate patient tolerance of the bronchoscopy
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
Patient satisfaction
Using a visual analogue scale from 0 to 10 to indicate patient satisfaction of the bronchoscopy
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
Adverse events
Development of adverse events during the bronchoscopic procedure, such as bleeding and oxygen desaturation
Time frame: Through the duration of the bronchoscopy exam, an average of 30 min
