Assessment of anaesthetists’ ability to predict difficulty of bag-mask ventilation

A proposal for a new scoring system to predict difficult ventilation through a supraglottic airway

“…However, insertion of or ventilation through a supraglottic airway device may also fail. 8 Therefore, preoperative assessment of not only difficult mask ventilation and tracheal intubation, [7][8][9][10][11][12][13][14] but also difficult ventilation through a supraglottic airway device may decrease the risk of major airway complication during difficult airway management.…”
