MeSH

Devices that cover the nose and mouth to maintain aseptic conditions often for the prevention of the spread of infections (e.g. COVID19) or to administer inhaled anesthetics or other gases.

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.

Year introduced: 1991(1963)
