Is this trial a fit for you?

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 evaluate the effectiveness of a combination of Anterior SupraScapular Nerve Block (ASSNB) and InfraClavicular Brachial Plexus Block (ICBPB) against the Costoclavicular Brachial Plexus Block (CCBPB) in managing postoperative pain for patients undergoing shoulder arthroscopy. Patients will be randomly assigned to one of two groups, with both groups receiving standard general anesthesia. The study will measure diaphragmatic excursion and postoperative pain levels at various intervals using a Numeric Rating Scale. The goal is to determine which anesthesia technique provides better pain relief and fewer side effects.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing shoulder arthroscopy.

How similar studies have gone: Previous studies have shown promising results with similar regional anesthesia techniques, indicating potential for success in this approach.
