16Comparative Treatments

i Description/ name of comparative treatments

There will be two kinds of approaches for performing the block, A & B, A = medial approach, B = lateral approach. There is a 50:50 chance of getting either method which is determined by the allocation. Your sensation to pinprick and motor function will be tested repeatedly after the block at 5-15 minutes intervals for 45 minutes. The onset time of sensory block will be compared for the two teniques.

23 Primary Outcome

The sensory and motor function in the ipsilateral hand and forearm will also be evaluated by a blinded observer (research nurse) at regular intervals for 45 minutes (5 min, 10 min, 15 min, 20 min, 30 min, and 45 min) after the infraclavicular BPB

24 Secondary Outcome

The occurance of paresthesia, abnormal sensation and motor weakness will be followed up at 48 hours and 1 week after the block.
