NCT03406533
Lead Sponsor
Changhai Hospital
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.

Primary Outcome Measures
NameTimeMethod
Cough scoreFrom 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 Outcome Measures
NameTimeMethod
Body movementFrom the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours

The numbers of the times of any body movement across the procedure

Satisfaction score of the patients and bronchoscopistsAcross the procedure, assessed up to 2 hours

Satisfaction score of the patients and bronchoscopists regarding to the sedation quality measured by a 0-100 visual analogue scale (VAS). 100 refers to the highest satisfaction degree while 0 refers to the worst satisfaction degree.

Amount of the rescue use of propofolAfter sedation induction, assessed up to 2 hours

The total amount of propofol used as a rescue therapy when the sedation is not deep enough as assessed by the anesthesiologists.

Recovery timeAfter termination of the sedation medication, assessed up to 2 hours

Duration of the recovery from sedation

Prevalence of the side effects of respiratory and circulatory systemAcross the sedation duration, assessed up to 2 hours

The number of the side effects in respiratory and circulatory system during the procedure, including hypertension, hypotension, tackycardia, bradycardia, hypoxia and larynx spasm.
