How many types of laryngeal mask airways are there?
Laryngeal mask airways come in several types, as follows: The LMA Classic is the original reusable design. The LMA Unique is a disposable version, making it ideal for emergency and prehospital settings. The LMA Fastrach, an intubating LMA (ILMA), is designed to serve as a conduit for intubation.
What is a Laryngeal Mask Airway Device?
A laryngeal mask airway (LMA) is a device inserted into the area behind the mouth and nose, connecting them to the food pipe (the pharynx) to allow ventilation, oxygenation, and administration of anesthetic gases, without the need for inserting a tube in the windpipe (endotracheal intubation).
What is the most significant disadvantage of the Laryngeal Mask Airway LMA over an endotracheal tube?
[1] the primary disadvantage and greatest concern with the use of the LAM is the inability to isolate the airway and to protect against the risk of aspiration. Indeed, the LAM has been shown to form a direct conduit between the laryngeal inlet and esophagus by enclosing both.
Is a Laryngeal Mask Airway an advanced airway?
The laryngeal mask airway (LMA) is an advanced airway alternative to ET intubation and provides comparable ventilation. It is acceptable to use the LMA as an alternative to an esophageal-tracheal tube for airway management in cardiac arrest.
What is the difference between LMA and ETT?
The LMA has many advantages over the ETT, such as having no direct contact with the tracheal mucosa, no need for direct laryngoscopy during inserting, and less adverse events such as lower frequency of coughing and decreased oxygen saturation during emergence, and lower incidence of sore throat in adults [6].
What is the difference between laryngeal mask airway and endotracheal tube?
The LMA has many advantages over an ET tube in that LMAs are less invasive, decrease airway trauma, decrease neck mobility requirements, and have a reduced risk of laryngospasm and bronchospasm.
What is LMA used for?
Laryngeal mask airways (LMA) are supraglottic airway devices. They may be used as a temporary method to maintain an open airway during the administration of anesthesia or as an immediate life-saving measure in a patient with a difficult or failed airway.
What is the difference between a endotracheal tube and a laryngeal mask?
How long can LMA stay in?
LMAs were typically designed for supporting sponataneous ventilation in minor surgery, i.e., surgery duration less than 30 minutes. However Proseal LMA (i.e, those incorporating gastric tube insertion channel) can be used for longer duration say 60-90 minutes.
When do you use LT and ETT?
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.
