Primary Outcome Measures:
  • Achieve safe, consistent, continous moderate sedation using Dexmedetomidine in advanced bronchoscopy procedures, alleviating the need for rapid sedative infusion. [ Time Frame: at conclusion of subject enrollemtn ]

Enrollment: 0
Study Start Date: April 2008
Estimated Study Completion Date: July 2012
Estimated Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
Subjects randomized to arm 1 of the study will recieve standard of care conscious sedation for EBUS; midasolam and or fentanyl.
Active Comparator: 2
Subjects undergoing EBUS randomized to arm 2 of the study will recieve demedetomadine hydrochloride plus standard of care conscious sedation
Drug: dexmedetomidine hydrochloride
Dose of 0.4ug/kg/hr to 1.5ug/kg/hr to achieve a RASS score of -1 to-3 during the bronchoscopy procedure. Dexmedetomidine will infused a half hour before the proceudure is started and will continue throughout the procedure. Traditional sedatives (midazolam and or fentanyl) will be given prn.
Other Name: Precedex

Detailed Description:
Dexmedetomidine hydrochloride as a single agent produces sedation, pain relief, anxiety redution, stable respiratory rates, and predictable cardiovascular responses. Dexmedetomidine facilitates patient comfort, compliance and comprehension by offering sedation with the ability to awaken patients. This study is being done to determine sedation efficacy and dosing; measure reduction or eliminate the need for rapid sedative infusion during bronchoscopy; improvement of patient comfort and safety during complex bronchoscopy; establish a new paradigm for moderate sedation during flexible bronchoscopy
