What is an LMA for anesthesia?
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.
Can a LMA be used for general anesthesia?
Abstract. Background: The laryngeal mask airway (LMA) is a safe and effective modality to maintain the airway for general anaesthesia during surgical procedures. The LMA is removed at the end of surgery and anaesthesia, when the patient maintains an adequate respiratory rate and depth.
What is an LMA tube?
The laryngeal mask airway (LMA) is a commonly used supraglottic airway. The LMA is an orally introduced supraglottic airway tube with a cuffed mask at one end that forms a low-pressure seal around the laryngeal inlet. LMA ventilation has several advantages over other methods.
When would you use an LMA instead of an 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].
When should a LMA be removed?
The LMA is removed at the end of surgery and anaesthesia, when the patient maintains an adequate respiratory rate and depth. This removal of the LMA can be done either when the patient is deep under anaesthesia (early removal) or only after the patient has regained consciousness (late removal).

Where is LMA inserted?
The LMA is a tube with an inflatable cuff that is inserted into the oropharynx. A: The deflated cuff is inserted into the mouth. B: With the index finger, the cuff is guided into place above the larynx. C: Once in place, the cuff is inflated.
What is the use of LMA in surgery?
LMA is used as an alternative to intubation where difficult intubation is anticipated. LMA is also useful for securing airway in emergency where intubation and mask ventilation is not possible. Laryngeal Mask Airway is used as an elective method for minor surgeries where anesthetist wants to avoid intubation.
What is LMA (laryngeal mask airway)?
Laryngeal Mask Airway – LMA. Laryngeal Mask Airway or LMA was discovered by Archies Brain so also called as a Brain Mask. LMA are special type of airways which are useful in difficult intubation. It is placed blindly in the oropharynx and the cuff is inflated with large volume of air tat is about 30 to 40 ml for a adult size tube.
What is the role of LMA in intubation?
LMA is used as an alternative to intubation where difficult intubation is anticipated. LMA is also useful for securing airway in emergency where intubation and mask ventilation is not possible.
How do you use a LMA tube?
Place your nondominant hand against/under the back of the patient’s head. Using your dominant hand, hold the LMA device like a pencil with your pointer finger lodged in the crevice between the tube and the tear dropped inflation tube. Place the tube on the hard palate and ensure the tip is not flipped up.
