Primary Outcome Measures:
  • Effect of median nerve perfusion with carpal tunnel release [ Time Frame: intraoperatively ]
    This study aims to examine the effect of carpal tunnel release on blood flow to the median nerve using SPY scope imaging.

Estimated Enrollment: 50
Study Start Date: July 2012
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Median nerve perfusion
Injection of indigocyanine green dye to evaluate perfusion of the median nerve with the SPY scope before and after carpal tunnel release
Drug: Indigocyanine green dye
Each patient will receive 1 injection of indigocyanine green dye using 2.5 mg/mL concentration of the imaging agent. 3mL of this mixture will be injected intravenously, followed by 10mL NS bolus, just prior to imaging with the SPY scope
Other Name: Indigocyanine green dye (ICG)

Detailed Description:
The study will involve patients undergoing carpal tunnel release surgery at our institution, with no change in the actual procedure performed. Using the SPY Scope, we will measure blood flow prior to the carpal tunnel release, and again measure once carpal tunnel release has been performed, in order to compare the values. This may add roughly 15 minutes to the total procedure time, however, no steps in the actual operation will be altered or affected in any way.
