Acute Airway Obstruction Caused by the New Single Use Laryngeal Mask Airway Supreme

摘要

Laryngeal masks are used broadly for elective and emergency airway management and are an essential part of the American and European difficult airway management algorithm.5'6 Due to their wide use, noticeable complications and side effects have been reported over the last years. The most common side effects are hoarseness and dysphagia. More threatening situations like impossible ventilation with desaturation are much less common. The rare reports of airway obstruction directly triggered by the laryngeal mask are swelling of the pha-ryngeal soft tissues caused by the leakage of irrigation fluid,7 herniation of the laryngeal mask airway cuff,8"10 foreign bodies (Ascaris lumbricoides11), and intermittent obstruction related to a vagal nerve stimulator.~(12)#
