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).
