Randomized Trial Comparing Intravenous Propofol and Inhaled Sevoflurane Anesthesia for Better Visibility During Arthroscopic Rotator Cuff Surgery

What this Trial Is About

Researchers are evaluating two anesthesia methods during arthroscopic rotator cuff repair surgery to determine which provides better visibility inside the shoulder joint. The study compares inhaled anesthesia with sevoflurane and total intravenous anesthesia TIVA using propofol. Visibility is important because no tourniquet can be applied during shoulder surgery, so bleeding must be minimized for a clear surgical view. This randomized, single-blind trial uses video assessments and artificial intelligence to analyze surgical visibility. Participants are randomly assigned to receive either inhaled anesthesia maintained with sevoflurane or continuous intravenous anesthesia maintained with propofol during surgery. Both groups receive induction drugs including propofol, atracurium, ketamine, and dexamethasone, with analgesia provided by remifentanil infusion. Norepinephrine is used as needed to maintain blood pressure. The trial evaluates the surgical field visibility during the procedure and compares additional outcomes like operating time, fluid use, hemodynamic stability, surgeon satisfaction, postoperative recovery, and environmental impact. During the study, participants undergo arthroscopic rotator cuff repair under general anesthesia combined with an interscalene block in the beach-chair position. Researchers assess surgical visibility using the modified Fromme-Boezaart score from video recordings of the surgery. They also monitor operative duration and other clinical factors. Participants are followed throughout the procedure with data collected intraoperatively. The trial runs from screening through surgery and recovery, with the main measurement taken during the operation.
