Summary

This study tests two numbing medicines given as a nerve block before shoulder surgery. The goal is to see which one controls pain better while reducing the risk of temporary diaphragm paralysis (which can affect breathing). About 184 adults having shoulder surgery will take part. Results will help doctors choose the safest pain relief option.
