About

Aged- related changes in upper airway anatomy may affect the overall performance of supraglottic airways significantly. In this study, investigator aim to compare the clinical performance, efficacy, and associated complications of the Proseal Laryngeal Mask and the Air-Q Intubation Laryngeal Airway in elderly patients.

Full description

Elderly patients are vulnerable to perioperative pulmonary complications during intubation and extubation. Supraglottic airway devices (SADs) have been utilized as a relatively easy method of airway management for resuscitation and difficult intubations and are used during elective general anesthesia with reduced airway complications compared to endotracheal intubation. SADs may help maintain hemodynamic stability as they require less anesthetic agents compared to endotracheal intubation. With aging, parapharyngeal fat accumulation increases, leading to pharyngeal collapse in elderly patients. Additionally, structural changes in the respiratory tract combined with physiological alterations in respiration may reduce oxygen saturation, blunt the hypoxic response, and increase postoperative respiratory complications. Acquired changes in pharyngeal muscle activity with age are thought to increase the likelihood of bony structural changes, such as retrognathia, which is typically considered a difficult airway. Therefore, these age-related changes may impact the clinical performance of SADs. ProSeal LMA is one of the most commonly used supraglottic airway devices in clinical practice. It was developed by modifying the classic LMA in the 2000s and features an inflatable cuff. Additionally, it has a gastric channel for gastric aspiration adjacent to the airway tube. Recently, SGAs (supraglottic airways) that do not require manual cuff inflation have been increasingly used in various clinical situations due to the advantages of eliminating manual cuff inflation and monitoring cuff pressure. Air-Q connects to an airway tube via a communication port that allows self-regulation of cuff pressure in response to airway pressure. In this study, investigator aim to compare the clinical performance, efficacy, and associated complications of the Proseal Laryngeal Mask and the Air-Q Intubation Laryngeal Airway in elderly patients.
