Primary Outcome Measures:
  • increase success rate of the block to produce surgical anesthesia and analgesia [ Time Frame: during and following surgical procedure ]

Enrollment: 218
Study Start Date: December 2006
Study Completion Date: March 2009
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Peripheral placement of local anesthesia
to receive ultrasound guided peripheral placement of local anesthetic
Procedure: Peripheral placement of local anesthesia
Peripheral placement of local anesthesia
Active Comparator: Central placement of local anesthesia
to receive central placement of local anesthetic
Procedure: Central placement of local anesthesia
Central placement of local anesthesia

Detailed Description:
A comparison of the infraclavicular placement of local anesthetic either centrally (posterior cord) vs peripheral placement (lateral or medial cord) using ultrasound guidance. This will be done to determine if ultrasound increases the success rate and if there is a difference in success rate between placing the local anesthetic centrally versus peripherally.
