What is a Perilaryngeal airway?

What is a Perilaryngeal airway?

The Perilaryngeal Airway (CobraPLA) is a novel airway device with a larger pharyngeal cuff (when inflated). We tested the hypothesis that the CobraPLA was superior to the LMA with regard to insertion time and airway sealing pressure and comparable to the LMA in airway adequacy and recovery characteristics.

What is the Cobra Perilaryngeal airway?

The Cobra Perilaryngeal Airway™ (Cobra PLA™) (Engineered Medical Systems, Indianapolis, IN) is a new supraglottic airway designed for spontaneous and controlled ventilation (Fig. 1). It has been used in the USA and in parts of Europe, but is not yet commercially available in the UK.

What are supraglottic airways?

Supraglottic airways (SGAs) are a group of airway devices that can be inserted into the pharynx to allow ventilation, oxygenation, and administration of anesthetic gases, without the need for endotracheal intubation.

What does Extraglottic airway mean?

INTRODUCTION Extraglottic airway devices are used to establish an airway for oxygenation and ventilation without entering the trachea. They are important tools for airway management and are used frequently in the prehospital environment, emergency department, operating room, and other settings.

What is the main disadvantage of a supraglottic airway?

They include regurgitation and aspiration of gastric contents, compression of vascular structures, trauma, and nerve injury. The incidence of such complications is quite low, but as some carry with them a significant degree of morbidity the need to follow manufacturers’ advice is underlined.

When would you use a supraglottic airway?

Supraglottic airway devices (SADs) are used to keep the upper airway open to provide unobstructed ventilation. Early (first-generation) SADs rapidly replaced endotracheal intubation and face masks in > 40% of general anesthesia cases due to their versatility and ease of use.

When is a LMA used?

Elective ventilation: The laryngeal mask airway (LMA) is often used for short surgical procedures in which endotracheal intubation is not necessary. Difficult airway: In some patients where endotracheal intubation fails, the LMA can be used as a rescue device for maintaining the airways.
