NCT07688889

Brief Summary

The primary objective of this study is to determine whether patients' physical characteristics hold predictive value regarding the difficulty or ease of performing an interscalene block. By pre-identifying patients prone to difficult blocks, predicting procedure duration, and elucidating the factors influencing ultrasound image quality, this study aims to contribute to clinical practice and patient safety.
