Summary

This study looked at how two different anesthesia methods—general anesthesia and a nerve block called interscalene block—affect blood flow and oxygen levels in the arm during shoulder surgery. Fifty adults having shoulder surgery took part. The goal was to see which method keeps blood moving better to the arm, which could help surgeons choose the safest option for patients.
