Sedation Strategies for Therapeutic Bronchoscopy

Not Applicable

Terminated

• Conditions: Bronchoscopy; Sedation
• Interventions: Drug: Dexmedetomidine; Device: Laryngeal mask; Drug: Remifentanil

• Registration Number: NCT03406546
• Lead Sponsor: Changhai Hospital

Brief 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.

Primary Outcome Measures

Name	Time	Method
Recovery time	After termination of the sedation medication, assessed up to 3 hours	Duration of the recovery from sedation

Secondary Outcome Measures

Name	Time	Method
Cost of anesthesia or sedation	Across the sedation or anesthesia, assessed up to 3 hours
Cough score	From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 3 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
The numbers of the times of body movement	From the completion of local anesthesia with lidocaine to the completion of bronchoscopy procedure, assessed up to 3 hours	The numbers of the times of any body movement across the procedure
Satisfaction score of the patients and bronchoscopists	Across the procedure, assessed up to 3 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.
Prevalence of the side effects of respiratory and circulatory system	Across the sedation or anesthesia, assessed up to 3 hours	The number of the side effects in respiratory and circulatory system during the procedure, including hypertension, hypotension, tackycardia, bradycardia, hypoxia and larynx spasm.
