Not Applicable

Completed

• Conditions: Pulmonary Disease
• Interventions: Device: Washing Pipe With a Spray Nozzle

• Registration Number: NCT05970848
• Lead Sponsor: National Taiwan University Hospital

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.

Arm && Interventions

Group	Intervention	Description
Group S	Washing Pipe With a Spray Nozzle	Group S patients will receive topical lidocaine anesthesia via the spray nozzle by the spray as-you-go technique during flexible bronchoscopy.

Primary Outcome Measures

Name	Time	Method
Cough rate	Through the duration of the bronchoscopy exam, an average of 30 min	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.

Secondary Outcome Measures

Name	Time	Method
Adverse events	Through the duration of the bronchoscopy exam, an average of 30 min	Development of adverse events during the bronchoscopic procedure, such as bleeding and oxygen desaturation
Procedure time	Through the duration of the bronchoscopy exam, an average of 30 min	The duration (minute) of the bronchoscopic procedure
Lidocaine dosage	Through the duration of the bronchoscopy exam, an average of 30 min	Total lidocaine doses dispensed during the bronchoscopic procedure
Patient satisfaction	Through the duration of the bronchoscopy exam, an average of 30 min	Using a visual analogue scale from 0 to 10 to indicate patient satisfaction of the bronchoscopy
Patient tolerance	Through the duration of the bronchoscopy exam, an average of 30 min	Using a visual analogue scale from 0 to 10 to indicate patient tolerance of the bronchoscopy
