Laryngeal
Mask - insertion technique
|
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. |
|
|
With the head extended and the neck
flexed, carefully flatten the
LM tip against the hard
palate.
|
|
|
|
Using continuos pressure, advance the LM into the hypopharynx until definite resistance is
felt.
|
|
|
|
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.
|
|
|
|
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.
