Background: SADs (Supraglottic Airway Devices) serve as an effective alternative to endotracheal intubation, bridging the gap between face masks and tracheal tubes in airway management. The LMA (Laryngeal Mask Airway) classic has been widely used as the gold standard supraglottic airway device since its introduction. However, newer devices such as the i-gel, which features a non-inflatable cuff, have been developed to improve ease of insertion, minimize tissue compression, and provide better airway seal pressure. This study aims to compare the ease of insertion, hemodynamic response, and clinical performance of i-gel and LMAclassic in anesthetized, paralyzed adult patients undergoing elective surgery. Materials and methods: A prospective, randomized, comparative study was conducted at Sparsh Hospital, Bengaluru, from April 2014 to May 2015. Adult patients undergoing elective surgeries under general anesthesia were randomly assigned to either the LMA Classic or i-gel group. The parameters assessed included ease of insertion, number of insertion attempts, time required for insertion, airway leak pressure, hemodynamic changes, and postoperative complications such as sore throat, dysphagia, and hoarseness. Results: The study found that the i-gel device demonstrated easier insertion, reduced insertion time, and required fewer insertion attempts compared to the LMA Classic. Airway leak pressure was significantly higher in the i-gel group, ensuring a better seal. Hemodynamic changes were minimal in both groups, with i-Gel showing better stability. Postoperative complications, including sore throat and dysphagia, were less frequent in the i-gel group compared to the LMA Classic. Conclusion: The i-gel supraglottic airway device offers advantages over the LMA Classic in terms of ease of insertion, shorter insertion time, and better airway seal. It is a suitable alternative for airway management in anesthetized, paralyzed adult patients undergoing elective surgeries.
