Efficacy and safety of superior trunk block versus interscalene block for post-operative analgesia in shoulder surgeries
The interscalene brachial plexus block is the gold standard analgesic technique for surgery involving the shoulder and upper arm. However, due to its complications as hemidiaphragmatic paralysis, the superior trunk block was developed in an attempt to reduce major complications.The utility of the superior trunk block has yet to be studied in shoulder surgeries.
