LMA Protector vs I-Gel in Low-Flow Anesthesia for Laparoscopic Cholecystectomy

This prospective randomized study aims to compare two second-generation supraglottic airway devices (SGAs), the I-Gel and the laryngeal mask airway (LMA) Protector, in patients undergoing laparoscopic cholecystectomy under low-flow desflurane anesthesia. The study evaluates the devices in terms of respiratory mechanics (dynamic compliance, peak inspiratory pressure, plateau pressure, and airway resistance), non-invasive perfusion parameters (oxygen reserve index, perfusion index, and pleth variability index), hemodynamic stability, ease of insertion, oropharyngeal leak pressure, and postoperative complication rates.
