Brief summary
The Laryngeal Mask Airway (LMA) has been used widely for different patients and found to be highly safe for adult and pediatric patients. However, the LMA has some limitations and weaknesses (e.g. more insertion attempts in 5% to 10 % of all cases. Despite the easy insertion of the LMA, it is crucial to check correct placement of the LMA airway.
