NCT05241977

Brief Summary

Various local anesthetic volumes are used in the literature for anterior suprascapular nerve block (ASSB). There are different studies between 15 ml and 5 ml. Effective local anesthetic volume studies for ASSB have not yet been performed. Our study is aimed to investigate the minimum effective local anesthetic volume for ASSB.
