The Laryngeal Mask Airway is an alternative airway device used for anesthesia and airway support. It consists of an inflatable silicone mask and rubber connecting tube. It is inserted blindly into the pharynx, forming a low-pressure seal around the laryngeal inlet and permitting gentle positive pressure ventilation. All parts are latex-free.

The Laryngeal Mask Airway is an appropriate airway choice when mask ventilation can be used but endotracheal intubation is not necessary.

-Non-fasted patients
-Morbidly obese patients
-Obstructive or abnormal lesions of the oropharynx
Advantages:
-Allows rapid access
-Does not require laryngoscope
-Relaxants not needed
-Provides airway for spontaneous or controlled ventilation
-olerated at lighter anesthetic planes
Special Features:
-May be used as a rescue airway and fiberoptic conduit when intubation is difficult, hazardous or unsuccessful
-It can be used for bronchoscopy in the awake or asleep patient
Tips for Success:
-Begin with ASA I & II patients
-Learn and use standard insertion technique
-Use appropriate size and do NOT overinflate
