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.

| Fentanyl | Drug | Fentanyl is another opioid drug used for analgesia to prevent bronchoscopy induced cough. |
|
| Dexmedetomidine | Drug | Dexmedetomidine is used for sedation in bronchoscopy with less impact on respiration. |
|
| Remifentanil | Drug | Remifentanil is used for analgesia to prevent bronchoscopy induced cough. |
|
| Propofol | Drug | Propofol is used for sedation with high efficacy but more side effect on respiration than dexmedetomidine. |
|
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. The scale score was determined by the subjective determination of the satisfaction on the sedation quality. |
| 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. | After sedation induction, assessed up to 2 hours |
| Recovery time | Duration of the recovery from sedation | 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, tachycardia, bradycardia, hypoxia and larynx spasm. | Across the sedation duration, assessed up to 2 hours |
