A Comparison of the Disposable Versus the Reusable Laryngeal Mask Airway in Paralyzed Adult Patients

Abstract

This randomized, single-blind, within-patient study of 60 adult patients shows that the disposable (polyvinyl chloride) and reusable (silicone) laryngeal mask airways perform similarly, but that the disposable laryngeal mask airway has more stable intracuff pressures during N2O anesthesia. Inflation of either device to high intracuff pressures produces a suboptimal seal.
