Clinical Trial 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.

Related Conditions & MeSH terms

• Bronchoscopy
• Sedation

Intervention

Drug:
• Midazolam
Midazolam is used as a common medication for sedation in all groups.
• Dexmedetomidine
Dexmedetomidine is used for sedation in bronchoscopy with less impact on respiration.
• Remifentanil
Remifentanil is used for analgesia to prevent bronchoscopy induced cough.
• Fentanyl
Fentanyl is another opioid drug used for analgesia to prevent bronchoscopy induced cough.
• Propofol
Propofol is used for sedation with high efficacy but more side effect on respiration than dexmedetomidine.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cough score	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	From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours
Secondary	Body movement	The numbers of the times of any body movement across the procedure	From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours
Secondary	Satisfaction score of the patients and bronchoscopists	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.	Across the procedure, assessed up to 2 hours
Secondary	Amount of the rescue use of propofol	The total amount of propofol used as a rescue therapy when the sedation is not deep enough as assessed by the anesthesiologists.	After sedation induction, assessed up to 2 hours
Secondary	Recovery time	Duration of the recovery from sedation	After termination of the sedation medication, assessed up to 2 hours
Secondary	Prevalence of the side effects of respiratory and circulatory system	The number of the side effects in respiratory and circulatory system during the procedure, including hypertension, hypotension, tackycardia, bradycardia, hypoxia and larynx spasm.	Across the sedation duration, assessed up to 2 hours
