NCT05970848

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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (5)

  • Procedure time

    Through the duration of the bronchoscopy exam, an average of 30 min

  • Lidocaine dosage

    Through the duration of the bronchoscopy exam, an average of 30 min

  • Patient tolerance

    Through the duration of the bronchoscopy exam, an average of 30 min

  • Patient satisfaction

    Through the duration of the bronchoscopy exam, an average of 30 min

  • Adverse events

    Through the duration of the bronchoscopy exam, an average of 30 min

Study Arms (2)

Group S

EXPERIMENTAL

Group S patients will receive topical lidocaine anesthesia via the spray nozzle by the spray as-you-go technique during flexible bronchoscopy.

Device: Washing Pipe With a Spray Nozzle

Group C

NO INTERVENTION

Group C patients will receive topical lidocaine anesthesia with the conventional method by the spray as-you-go technique during flexible bronchoscopy.

Interventions

Administration of topical airway anesthesia via a washing pipe with a spray nozzle using the spray-as-you-go technique

Group S
