A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to determine the minimum effective dosage of levobupivacaine needed to achieve a successful ultrasound-guided superior trunk block in patients undergoing shoulder arthroscopic surgery. By focusing on this specific nerve block, the research seeks to minimize postoperative pain while reducing the risk of complications associated with traditional anesthesia methods. The study will involve patients classified as ASA physical status I-III, ensuring a controlled and safe environment for the intervention. The ultimate goal is to establish a dosage that effectively blocks pain in at least 90% of participants.
