A study testing Midazolam, Dexmedetomidine and Remifentanil in people with Bronchoscopy and Sedation, run by Changhai Hospital at 1 site in China.
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. Read more about this study

About this study
Official title: The Effect and Safety of Different Sedation Strategies for Diagnostic Bronchoscopy
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.
- Conditions
- Bronchoscopy, Sedation
- Being tested
- Midazolam, Dexmedetomidine, Remifentanil, Fentanyl, Propofol
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MidazolamDrug
Midazolam is used as a common medication for sedation in all groups.
DexmedetomidineDrug
Dexmedetomidine is used for sedation in bronchoscopy with less impact on respiration.
RemifentanilDrug
Remifentanil is used for analgesia to prevent bronchoscopy induced cough.
FentanylDrug
Fentanyl is another opioid drug used for analgesia to prevent bronchoscopy induced cough.
PropofolDrug
Propofol is used for sedation with high efficacy but more side effect on respiration than dexmedetomidine.
| Study group | Role | What they receive |
|---|---|---|
| Group F | Experimental | Sedated with midazolam and fentanyl Receives: Drug: Midazolam; Drug: Fentanyl |
| Group DR | Experimental | Sedated with midazolam, dexmedetomidine and remifentanil Receives: Drug: Midazolam; Drug: Dexmedetomidine; Drug: Remifentanil |
| Group DF | Experimental | Sedated with midazolam, dexmedetomidine and fentanyl Receives: Drug: Midazolam; Drug: Dexmedetomidine; Drug: Fentanyl |
| Group PR | Experimental | Sedated with midazolam, propofol and remifentanil Receives: Drug: Midazolam; Drug: Remifentanil; Drug: Propofol |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 2 hours
Secondary outcomes (5)
Body movement
The numbers of the times of any body movement across the procedure
Measured: 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
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.
Measured: Across the procedure, assessed up to 2 hours
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.
Measured: After sedation induction, assessed up to 2 hours
Recovery time
Duration of the recovery from sedation
Measured: After termination of the sedation medication, assessed up to 2 hours
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.
Measured: Across the sedation duration, assessed up to 2 hours
