Answer

Answer

After failed intubation, the LMA can be used as a rescue device. [12, 13]

In the case of the patient who cannot be intubated but can be ventilated, the LMA is a good alternative to continued bag-valve-mask ventilation because LMA is easier to maintain over time and it has been shown to decrease, though not eliminate, aspiration risk. [8, 9]

In the case of the patient who cannot be intubated or ventilated, a surgical airway is indicated and should not be delayed. However, if the LMA is at hand, it can easily be attempted quickly, while an assistant simultaneously prepares for cricothyroidotomy. [7]
