Dexmedetomidine vs. Propofol for Cataract Surgery

This study has been completed.

First received: November 5, 2008

Last verified: November 2008
The use of dexmedetomidine in cataract surgery is still limited and to date only one study has examined anesthetic technique in this patient population. This pilot study will therefore compare the use of dexmedetomidine and propofol in subjects undergoing cataract surgery. The primary endpoint will be based on simple cardiorespiratory measures often associated with complications from sedation as well as assessment of the achieved sedation by the attending anesthesiologist and surgeon.

Primary Outcome Measures:
  • To compare select cardiorespiratory effects of dexmedetomidine sedation to those of propofol sedation in patients undergoing cataract surgery. [ Time Frame: 1 day ]

Enrollment: 24
Study Start Date: April 2008
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Propofol Drug: Propofol
continuous propofol infusion at 50-100mcg/kg/min until a Ramsay score of 3 or Bis score of 60-80 is achieved
Experimental: Dexmedetomidine Drug: dexmedetomidine
Propofol or dexmedetomidine infusion will be started according to the randomized treatment allocation. The propofol group will receive a bolus of 2mg midazolam and 100mcg fentanyl and then continuous propofol infusion at 50-100mcg/kg/min until a Ramsay score of 3 or Bis score of 60-80 is achieved. The dexmedetomidine group will receive a bolus of dexmedetomidine 1mcg/kg for 10 minutes and then a continuous infusion of dexmedetomidine 0.2-0.7mcg/kg/hr until a Ramsay score of 3 or a Bis score of 60-80 are achieved.
Drug: Dexemedetomidine
continuous infusion of dexmedetomidine 0.2-0.7mcg/kg/hr until a Ramsay score of 3 or a Bis score of 60-80 are achieved.
