What this trial studies

This study aims to compare the hemodynamic changes and cerebral oxygenation during arthroscopic shoulder surgeries using two anesthetic techniques: interscalene block with sedation and interscalene block with general anesthesia. Participants will be monitored using either continuous non-invasive monitoring or standard hemodynamic monitoring to assess cardiac output, blood pressure, heart rate, and oxygen saturation. The study will analyze these variables intraoperatively and evaluate postoperative outcomes such as delirium, hospital stay length, complications, and pain levels. The goal is to determine the benefits of continuous non-invasive monitoring in improving patient outcomes during these procedures.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for elective arthroscopic shoulder surgery in a beach chair position.

Not a fit: Patients undergoing emergency surgeries or those with significant comorbidities such as pulmonary disease or previous cerebrovascular events may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance patient safety and recovery during shoulder surgeries by optimizing hemodynamic management.

How similar studies have performed: Previous studies have shown promising results with continuous non-invasive monitoring in various surgical settings, suggesting potential benefits in this approach.
