Official Title: Costoclavicular vs Paracoracoid Approach to Infraclavicular Brachial Plexus Block: a Feasibility Study
Brief Summary: Patients for upper limb surgeries who are candidates for infraclavicular block will be screened. Two techniques of infraclavicular block will be compared. Measured outcomes are performance times, block onset times, patient satisfaction, quality of block, and requirement for supplementary analgesia.
Detailed Summary: Infraclavicular brachial plexus block under ultrasound guidance is used for surgeries on the upper limb. Traditionally, the block is performed at the lateral infraclavicular fossa where the cords are variable in position relative to the axillary artery. A recently introduced technique is the costoclavicular approach where the cords are viewed as relatively more superficial and clustered together compared to the traditional technique. Those meeting the inclusion criteria and will consent to participate in the study will be randomized to have either an infraclavicular block in the paracoracoid approach (Group 1) or an infraclavicular block in the costoclavicular approach (Group 2). All groups will have the same injectable volume (35 mls) and local anesthetic concentration (ropivacaine 0.5%). There will be 35 study patients for each group for a total of 70 patients.

Current Primary Outcome: Block onset time [ Time Frame: 1 hour ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Procedure duration [ Time Frame: 1 hour ]From the time the US probe touches the skin to the time the needle is removed
- Quality of block [ Time Frame: 1 hour ]
- Patient satisfaction [ Time Frame: 1 day ]Satisfaction score (VAS ranging from 0 = completely dissatisfied to 10 = completely satisfied)
- Requirement for supplemental analgesia or anesthesia [ Time Frame: 1 day ]Quality of block will be assessed if adequate for surgery
Original Secondary Outcome:
- Procedure duration [ Time Frame: Block performance time and block onset time ]From the time the US probe touches the skin to the time the needle is removed
- Quality of block [ Time Frame: Assessment up to 30 minutes after block completion ]
- Patient satisfaction [ Time Frame: 1 day ]Satisfaction score (VAS ranging from 0 = completely dissatisfied to 10 = completely satisfied)
- Requirement for supplemental analgesia or anesthesia [ Time Frame: 1 day ]Quality of block will be assessed if adequate for surgery
