LMA except?
a) More reliable than face mask
b) Prevent aspiration
c) Alternative to Endotracheal intubation
d) Does not require laryngoscope & visualization
Correct Answer - B
Ans. B. Prevent aspiration
LMA is intermediate between the face mask and Endotracheal
intubation in terms of reliability,
invasiveness and facilitation of gas exchange (face mask has
minimum and endotracheal intubation has maximum).
LMA does not prevent asPiration + should not be used in full

minor surgeries, where anaesthetist wants to avoid intubation.
LMA is introduced blindly (without laryngoscopy)
