Overview
Brief Summary
Diagnostic bronchoscopy is an invasive procedure performed to diagnose respiratory diseases. But pain has been complained by most of the patients receiving such procedures. Sedation or anesthesia was required by both of the patients and bronchoscopists. Unfortunately, no consensus has been made upon the sedation strategies. Multiple sedation approaches have been applied, such as midazolam and fentanyl, remifentanil and propofol, dexmedetomidine and propofol. The present study was designed to compare these protocols in sedation for diagnostic bronchoscopy.

Outcomes
Primary Outcomes
Cough score
Time Frame: From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours
Cough score across the procedure will be classified into 4 degree (1-4) as follows. 1 = none, 2 = one gag or cough only, 3 = \>1 gag or cough, but acceptable conditions, 4 = unacceptable conditions
Secondary Outcomes
- Body movement(From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours)
- Satisfaction score of the patients and bronchoscopists(Across the procedure, assessed up to 2 hours)
- Amount of the rescue use of propofol(After sedation induction, assessed up to 2 hours)
- Recovery time(After termination of the sedation medication, assessed up to 2 hours)
- Prevalence of the side effects of respiratory and circulatory system(Across the sedation duration, assessed up to 2 hours)
