Devices introduced into the supraglottic space (not through the vocal cords). Laryngeal masks (LMA) are most common and well-known. There are currently a variety of different shapes and sizes available.
- requires shorter training time than laryngoscopy
- use in cases where direct laryngoscopy is impossible (eg. due to the patient's position)
- effective ventilation and oxygenation
- without the risks associated with endotracheal intubation
- effective even for the smallest children
- does not provide 100% protection against aspiration
- inefficient ventilation in the case of laryngospasm
- risk of dislocation when changing patient position
Procedure:
It is introduced blindly (without the use of a laryngoscope). For ease of insertion, the distal end is lubricated. The tightness of the supraglottic device is provided by a specially shaped cuff (gel, plastic, or inflatable).
