It channels oxygen and inhalational anaesthetic to the lungs. It can be used during anaesthesia, or while a patient is unconscious. Laryngeal mask airways are designed to be an easy way to secure the airway and ventilate a patient – they are easier to place than tracheal intubation due to the lack of muscle relaxants and laryngoscopy.
A cuffed endotracheal tube used in tracheal intubation Tracheal intubation , often simply referred to as intubation, is the placement of a flexible plastic or rubber endotracheal tube (ETT) into the trachea to maintain an open airway, allow for effective ventilation, protect the airway from aspiration (when a cuffed ETT is used), and to serve ...

In these circumstances, endotracheal intubation is generally preferred. The most commonly used extraglottic device is the laryngeal mask airway (LMA). An LMA is a cuffed perilaryngeal sealer that is inserted into the mouth and set over the glottis. Once it is in its seated position, the cuff is inflated. [30]
The laryngeal tube is also recommended for medical personnel not experienced in tracheal intubation, and as a rescue device when intubation has failed in adults. [16] According to the manufacturer the use of Laryngeal tubes is contraindicated in people with an intact gag reflex , known oesophageal disease , and people who have ingested caustic ...
Inflation of the cuff in the esophagus allows a level of protection against aspiration of gastric content similar to that found in the laryngeal mask. [2] The simplicity of placement is the main advantage of the Combitube over endotracheal intubation. When intubating with a traditional endotracheal tube, care must be taken to visually ensure ...
Intubation, which provides a clear route for the air can be either an endotracheal tube, inserted through the natural openings of mouth or nose, or a tracheostomy inserted through an artificial opening in the neck. In other circumstances simple airway maneuvers, an oropharyngeal airway or laryngeal mask airway may be employed.
The laryngeal mask airway (LMA) is a tube with an inflatable cuff. A laryngeal mask airway can be positioned in the lower oropharynx to prevent airway obstruction by soft tissues and to create a safe channel for ventilation. The laryngeal mask airway is the standard rescue ventilation when endotracheal intubation cannot be accomplished.
