Summary
The standard hospital procedure calls for the patient to undergo Interscalene block under
ultrasound with or without nerve stimulation guidance prior to going to operating room (OR).
The block utilizes a 40 ml mixture of 0.5% Ropivacaine and Lidocaine 1.5%. At this time the
patient receives preliminary sedation with Midazolam 1mg IV and Fentanyl 50 mcg IV. The
participant is then brought to the OR and prolonged sedation is initiated, randomly using
either Dexmedetomidine or Propofol.
The primary objective of the present study is to use Dexmedetomidine for sedation, and
compare the outcomes with Propofol sedation. The investigators will enroll 50 patients for
this study.
Our hypothesis is that Dexmedetomidine will cause fewer episodes of intermittent apnea, and
reduced need for supplemental medication for sedation, compared to Propofol
