What is an Extraglottic airway device?

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 purpose of advanced airway device?

It is frequently performed in critically injured, ill or anesthetized patients to facilitate ventilation of the lungs, including mechanical ventilation, and to prevent the possibility of asphyxiation or airway obstruction.

What is the best supraglottic device?

Conclusions. Most study parameters for the Supreme LMA and i-gel were found to be superior to the other three tested supraglottic airway devices when inserted by novice military operators.

How long can you use an LMA for?

The laryngeal mask airway (LMA) has been used successfully in numerous cases since its introduction more than 30 years ago. While some contraindications to LMA use are absolute others are less well defined. An upper time limit of three hours has been recommended for patients whose airway is managed with an LMA.

How does a king tube work?

The device is a latex-free, single lumen tube with a distal and proximal balloon that occludes the esophagus and oropharynx, creating a direct route for ventilations through the larynx and trachea.

When would you use a supraglottic airway device?

A supraglottic airway (SGA) is indicated for securing an airway during resuscitation of an unconscious patient. An SGA is an advanced airway technique to assist with oxygenation and ventilation.

Do you need to paralyze for LMA?

Paralysis is not necessary for LMA insertion and maintenance. Movement and coughing upon insertion should be particularly avoided in patients who are at risk for cervical spine injuries; therefore, adequate anesthesia is particularly important in these patients. Children may require deeper anesthesia.

Why is an LMA not suitable for long term intubation?

The LMA-Classic was unsuitable, the airway tube was too narrow and too long to allow the endotracheal tube (ETT) to be reliably placed distal to the vocal cords, and it was subsequently difficult to remove the LMA over the ETT after tracheal intubation.

Is an LMA considered intubation?

The LMA can be used as a conduit for intubation, particularly when direct laryngoscopy is unsuccessful. An ETT can be passed directly through the LMA or ILMA. Intubation may also be assisted by a bougie or fiberoptic scope.
