Laryngeal mask airway ventilation is easy to use compared with endotracheal intubation, requires no stimulation of the glottis and trachea and does not affect the ciliary movement of the tracheal mucosa. Its prominent advantage is the elimination of mechanical stimulation to the tracheal larynx (40).

In summary, LMA may be a promising method for airway management alternatives to traditional ETT. Much less anaesthetics and stimulation were used on patients with LMA, which further increases the stability of the anaesthetic effect and improves patient recovery after surgery.

Therefore, in adults, it is recommended to use LMA as a substitute for tracheal intubation, especially in patients with a history of intubation, the possibility of difficult intubation diagnosed by an anesthesiologist, and patients whose intubation has failed and ventilation can be performed with a mask (10-12).

[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.
