About this study

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.

Treatment and study plan

interscalene block

Procedure

will receive a 20 ml mixture of local anesthetic solution prepared as 10 ml of bupivacaine 0.5% diluted with 10 ml normal saline 0.9% will be injected in interscalene block.

Superior trunk block

Procedure

will receive a 20 ml mixture of local anesthetic solution prepared as 10 ml of bupivacaine 0.5% diluted with 10 ml normal saline 0.9% will be injected in superior trunk block.

Primary outcomes
