  Purpose

The purpose of this study is to compare the rate of complete sensory block at 30 minutes following ultrasound-guided single injection infraclavicular block and ultrasound-guided double injection axillary block. The investigators research hypothesis is that both blocks will show comparable rates of complete sensory block at 30 minutes.

Primary Outcome Measures:
  • Number of patients with complete sensory block [ Time Frame: 30 minutes after block completion ] [ Designated as safety issue: No ]
    Complete sensory block is defined by anesthesia to cold sensation in the ulnar, radial, median and musculocutaneous nerves territories.


Secondary Outcome Measures:
  • Number of patients with complete motor blocks [ Time Frame: 30 minutes after block completion ] [ Designated as safety issue: No ]
    Complete motor block is defined by paralysis in the ulnar, radial, median and musculocutaneous nerves territories.

  • Time to complete sensory and motor blocks. [ Time Frame: 0, 5, 10, 15, 20, 25 and 30 minutes after block completion ] [ Designated as safety issue: No ]
    Sensory and motor blocks are evaluated in the median, ulnar, radial and musculocutaneous nerves territories.

  • Procedure-related pain on a visual analog pain scale [ Time Frame: During the nerve block procedure ] [ Designated as safety issue: No ]
  • Number of patients with adverse events related to nerve block [ Time Frame: 24 hours and 1 month after surgery ] [ Designated as safety issue: Yes ]
  • Surgical block success rate [ Time Frame: End of surgery ] [ Designated as safety issue: No ]
    Surgical block success is defined by a nerve block allowing surgery without a rescue block, an infiltration of local anesthetics by the surgeon, administration of analgesics for pain in the surgical field or a general anesthesia.

  • Performance time of the nerve block [ Time Frame: During the performance of the block ] [ Designated as safety issue: No ]
    Performance time is defined as the sum of imaging time (defined as the time elapsed from the moment the Doppler probe is in contact with the patient to the insertion of the Tuohy needle) and needling time (from the insertion of the needle to its complete removal).

Study Start Date: September 2012
Study Completion Date: March 2013
Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Ultrasound-guided infraclavicular block
Ultrasound-guided single injection infraclavicular block
Procedure: Ultrasound-guided infraclavicular block
Ultrasound-guided single injection infraclavicular block: using an in-plane technique, 30 mL of mepivacaine 1.5% is injected at the posterior aspect of the artery.
Active Comparator: Ultrasound-guided axillary block
Ultrasound-guided double injection axillary block
Procedure: Ultrasound-guided axillary block
Ultrasound-guided double injection axillary block: using an in-plane technique, 25 mL of mepivacaine 1.5% is injected postero-medial to the artery. During needle withdrawal, 5 mL of the same solution is injected close to the musculocutaneous nerve.
