Laryngeal Mask - insertion technique
 

1)

 

Tightly deflate the cuff.

2)

Lubricate the posterior surface of the laryngeal mask (LM) with water-soluble lubricant.

 

 

3) Hold the LM like a pen, with the index finger placed at the junction of the cuff and the tube.

 

 

4)

With the head extended and the neck flexed, carefully flatten the

LM tip against the hard palate.
 

 

 

5)

Using continuos pressure, advance the LM into the hypopharynx until definite resistance is felt.

 

 

 

6)

Before removing the index finger, gently press down the tube with the other hand.

This prevents the laryngeal mask from being pulled out of place.
 

 

 

 

 

 

7)

With the LM tube free, inflate the cuff with an air volume just enough to obtain a seal (to a pressure of approximately 60 cm H2O)

Never overinflate the cuff.
