Washing Pipe With a Spray Nozzle for Topical Anesthesia During Bronchoscopy

Study Overview
=================
Brief Summary
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | Through the duration of the bronchoscopy exam, an average of 30 min | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Procedure time | The duration (minute) of the bronchoscopic procedure | Through the duration of the bronchoscopy exam, an average of 30 min | 
| Lidocaine dosage | Total lidocaine doses dispensed during the bronchoscopic procedure | 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 | 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 | 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 | Through the duration of the bronchoscopy exam, an average of 30 min |
