Sponsor's own description

Currently, research on laryngeal mask airway (LMA) has been continuously deepened both domestically and internationally, which has greatly promoted the optimization process of clinical application and related management strategies. Numerous domestic and foreign research findings have consistently emphasized the key role of LMA cuff pressure monitoring in reducing postoperative complications, especially in alleviating sore throat and dysphagia. Foreign studies have extensively covered the research and development innovation of LMA devices, as well as comprehensive comparative analyses with other airway management methods such as endotracheal intubation, providing rich perspectives for expanding the application of LMA and improving its application effects. In contrast, domestic studies have distinct pertinence, focusing on application exploration in specific populations and clinical practice scenarios, and have provided important evidence for the safe and effective use of LMA in specific groups through in-depth research. However, it is undeniable that there are obvious deficiencies in both domestic and foreign research regarding the application of continuous monitoring and progressive regulation of LMA cuff pressure in elderly patients-a crucial field. Due to the natural decline of physiological functions, elderly patients face an increased risk of complications such as pulmonary and extrapulmonary complications, as well as pharyngolaryngeal complications, when using LMA during the perioperative period. Therefore, it is particularly urgent to carry out continuous pressure monitoring and progressive regulation of LMA cuff pressure, and to further explore the optimal range of LMA cuff pressure. This study will not only fill the current research gap but also provide solid support for the safe and efficient airway management of elderly patients during the perioperative period.
