Comparison of Ultrasound-Guided Infraclavicular Block and Ultrasound-Guided Axillary Block
- Conditions
- Anesthesia
- Registration Number
- NCT01761175
- Lead Sponsor
- CHU de Quebec-Universite Laval
- Brief Summary
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
Name Time Method Number of Patients With Complete Sensory Block 30 minutes after block completion Complete sensory block is defined by anesthesia to cold sensation in the ulnar, radial, median and musculocutaneous nerves territories.
- Secondary Outcome Measures
Name Time Method Procedure-related Pain on a Visual Analog Pain Scale After the nerve block procedure ended, up to 5 minutes. Pain was evaluated by the patient on a visual analog pain scale ranging from 0 (no pain) to 10 (worst pain of their life).
Number of Patients With Postoperative Adverse Events Related to Nerve Block 1 month after surgery Adverse events were defined by residual numbness, loss of sensitivity or weakness in the operated arm related to block performance or signs of hematoma or infection at the puncture site.
Number of Patients With Complete Motor Blocks 30 minutes after block completion Complete motor block is defined by paralysis in the ulnar, radial, median and musculocutaneous nerves territories.
Time to Complete Sensory Block. 5, 10, 15, 20, 25 and 30 minutes after block completion Complete sensory block is defined by anesthesia to cold sensation in the median, ulnar, radial and musculocutaneous nerves territories.
Time to Complete Motor Block 5, 10, 15, 20, 25 and 30 minutes after block completion Complete motor block is defined by paralysis in the median, ulnar, radial and musculocutaneous nerves territories.
Surgical Block Success Rate End of surgery 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 During the performance of the block 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).
Duration of Surgery The end of surgery Tourniquet Use The end of surgery Number of participants who had a tourniquet during the surgery
Duration of Tourniquet The end of surgery The total time the tourniquet was left inflated
