InterventionPrimary outcome is the success or failure of the supraclavicular block. This will be assessed by testing the patient's ability to detect cold sensation by application of a cold alcohol swab to the skin. This will be measured by asking the patient to score the cold sensation from 0 - 10. Any score higher than 0 will be deemed an unsuccessful block. This assessment will be carried out at 15 minute intervals for upto 45 minutes after the block has been performed. There will be no follow up after this.
Intervention typeProcedure/Surgery
Primary outcome measure(s)Ability to detect cold sensation by application of cold alcohol swab to the skin at the sensory dermatomes of the median, ulnar, radial and musculocutaneous nerves in the upper limb, measured 45 minutes after performing the supraclavicular block.
