It disturbs the quality of anesthesia during brachial plexus block for distal upper-limb surgery. Current evidence shows that adding an intercostobrachial nerve block using the landmark-based technique can improve analgesia for medial upper-arm procedures. The serratus anterior plane block has also been proposed as an adjunct that may cover the intercostobrachial nerve territory. However, the landmark intercostobrachial nerve technique relies on a blind injection and may give inconsistent results. Moreover, high-quality head-to-head data comparing ultrasound-guided intercostobrachial nerve block with serratus anterior plane block for tourniquet pain prevention are lacking.",[29,35],{"label":30,"type":31,"description":32,"interventionNames":33},"Selective ultrasound guided Intercostobrachial nerve block","ACTIVE_COMPARATOR","After a brachial plexus block, participants will receive a selective Intercostobrachial nerve block.
