Clinical Trial Summary

Therapeutic bronchoscopy is a common procedure to treat respiratory diseases. The procedure includes stent implantation, bronchus dilation, electronic incision, laser therapy, and so on. Most of these procedures are painful and require general anesthesia. Conventionally, the general anesthesia for therapeutic bronchoscopy was performed using laryngeal mask. But in the previous experiences, the investigators found that sedation with dexmedetomidine and remifentanil was as effect as laryngeal mask anesthesia. The present study was performed to compare the two approach for sedation or anesthesia in therapeutic bronchoscopy.

Related Conditions & MeSH terms

• Bronchoscopy
• Sedation

Intervention

Drug:
• Dexmedetomidine
Dexmedetomidine was used as a sedation agent with less side effect on respiratory system.
• Remifentanil
Remifentanil was used to prevent cough induced by bronchoscopy.

Device:
• Laryngeal mask
Laryngeal mask was used to ensure respiration function during general anesthesia.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recovery time	Duration of the recovery from sedation	After termination of the sedation medication, assessed up to 3 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 3 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 or anesthesia, assessed up to 3 hours
Secondary	Cost of anesthesia or sedation		Across the sedation or anesthesia, assessed up to 3 hours
Secondary	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 3 hours
Secondary	The numbers of the times of 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 3 hours
