Estimated Enrollment: 210
Study Start Date: January 2010
Study Completion Date: February 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Neurostimulation
Block catheter will be introduced using neurostimulation
 Procedure: Ultrasound
Block catheter will be introduced using ultraosound
Active Comparator: Ultrasound
Block catheter will be introduced using ultrasound
 Procedure: Ultrasound
Block catheter will be introduced using ultraosound

Detailed Description:

In a multidisciplinary, observer blinded, prospective, single center, randomized study, success rate of US guided versus neurostimulation guided catheter placement for continuous infraclavicular block in patients scheduled for upper limb surgery will be studied. Block effectiveness, time taken, discharge from recovery, postoperative pain and disability and patient acceptance will be studied in 210 patients.
