In the past the incidence of tourniquet pain, associated with different nerve blocks has been estimated in clinical trials for which it was a secondary outcome measure. One recent meta-analysis addressed the question: is infraclavicular block (ICB) associated with a lesser incidence of tourniquet pain compared to other brachial plexus blocks. The studies selected by this meta-analysis used different types of nerve block. However it did not address the clinically relevant question: using standard techniques for ultrasound guided brachial plexus block (USgBPB) is the infraclavicular approach associated with a lesser incidence of tourniquet pain than the axillary approach? The following nerves contribute to the perception of tourniquet pain: musculocutaneous, radial, medial cutaneous brachial (MCBN) and intercostobrachial (ICBN). The potential advantage of the ICB over the axillary brachial plexus block (ABPB) in regards to tourniquet pain comes from anatomical reasons. In the pyramid shaped infraclavicular space the cords are much closer to each other; thus the likelihood of achieving effective MCBN and ICBN block is greater. The infraclavicular route has proven to result in an equally effective, reliable and safe block of the brachial plexus, compared to the axillary approach. We hypothesize that the incidence of tourniquet pain is less with infraclavicular block compared to axillary brachial plexus block.
