Evaluation of Second-generation laryngeal mask airway (LMA Protector) for laparoscopic surgeries – A Randomized Controlled Trial

General anaesthesia is widely practiced for laparoscopic abdominal surgery as pneumoperitoneum increases the risk of pulmonary aspiration., and this typically facilitated using an endotracheal tube (ETT) for airway management. But many of these laparoscopic surgeries are day care surgeries and used of ETT in these cases can lead to cumbersome postoperative pharyngodynia thereby increasing the duration of hospital stay and thereby increasing the health care cost. Hence now a days supraglottic airway devices (SGA) are preferred over ETT in these daycare cases because of less incidence of post operative pharyngodynia. However still many cases postoperative pharyngodynia occurs despite using second generation SGA because of variable intracuff pressure of SGA perioperatively. This change in intracuff pressure occurs due to change in patient positioning and creation of pneumoperitoneum perioperatively. Recently introduced The LMA Protector has dual gastric access and integrates “Second Seal Technology/second generation LMA” to secure the distal tip at the upper oesophageal sphincter. In this way an oesophageal seal is facilitated, and the respiratory tract is isolated from the digestive tract.[3] It also has inbuilt color-coded continuous cuff pressure monitoring system. Despite these developments, the scarcity of prospective research examining the suitability of different second-generation SGA which will cause less postoperative pharyngodynia and decrease hospital stay in day care surgery underscores the need for further investigation. Therefore, this study aims to evaluate the feasibility and safety of employing two second-generation SGA namely LMA Protector and Ambu AuraGain in patients undergoing laparoscopic surgeries, addressing a critical gap in the literature, and informing clinical practice regarding optimal airway management strategies in this context.
