Conditions
Brief summary
To determine whether ultrasound guided supraclavicular block provides more rapid onset of surgical analgesia than infraclavicular block. If the primary hypothesis is confirmed, this study will provide evidence supporting the use of the supraclavicular block for hand surgery. Increased exposure of the techniques may promote their uptake in this setting.
Interventions
Infraclavicular block Infraclavicular (IB) Group The needle will be advanced just posterior to the axillary artery. Following standard intravascular injection precautions, 30mL of 2% lignocaine will then be injected. Supraclavicular(SB) Group The needle will be advanced superficially in a medial direction to just inferior to the brachial plexus cords just lateral to the subclavian artery. Following standard intravascular injection precautions, 30mL of 2% lignocaine will then be injected. The duration of each procedure is approximately 15 minutes, and the overall intervention approximately 30 minutes.
