Abstract
Background
Airway management in the prone position remains a major challenge in anesthesia, particularly during short urologic procedures. Although endotracheal intubation (ETT) is considered the standard technique, the Classic laryngeal mask airway (LMA) has emerged as a less invasive alternative in patients without an anticipated difficult airway. This study aimed to compare the efficacy and safety of Classic LMA versus ETT for airway management in prone-position urologic surgeries.
Methods
In this randomized clinical trial, 70 patients undergoing prone-position urologic surgery with an operative duration of ≤ 90 min were assigned to either the Classic LMA group or ETT group (n = 35 each). Primary outcomes included intraoperative ventilatory performance assessed by peak airway pressure (Ppeak), need for conversion of airway technique, and airway-related complications. Secondary outcomes included intraoperative hemodynamic and respiratory parameters, including heart rate (HR), systolic and diastolic blood pressure (SBP/DBP), oxygen saturation (SpO2), end-tidal carbon dioxide (ETCO2), Ppeak, minute ventilation (VE), and postoperative complications.
