ClinConnect Summary

This clinical trial is looking at how much of a local anesthetic called levobupivacaine is needed to effectively numb the shoulder area for patients undergoing a specific type of shoulder surgery called arthroscopic rotator cuff repair. The goal is to find the smallest amount that can still provide good pain relief for at least 90% of the patients. The study is currently recruiting participants, and it welcomes individuals between the ages of 65 and 74 who are in good health (American Society of Anesthesiologists physical status I-III) and scheduled for this surgery.

To participate, patients should not be pregnant, have any skin infections at the injection site, or a history of allergies to local anesthetics. They also should not have any bleeding disorders or pre-existing nerve or muscle diseases. If eligible, participants can expect to receive the local anesthetic through an ultrasound-guided procedure, which helps ensure the medication is delivered precisely where it's needed to maximize pain relief during their surgery. This study aims to improve pain management during these surgeries, making recovery easier for patients.
