The difficult airway

Securing the airway in a dyspneic patient is a challenging task because of the myriad causes and presentations. Initial assessment may demonstrate factors indicative of upper airway abnormalities; however, they may not be specific nor sensitive enough to accurately predict difficult intubation. A well-equipped airway cart must be immediately available. A standardized escalating approach to secure the airway in a difficult situation begins with a rapid sequence of attempts at standard intubation, followed by attempted tube introduction over a bougie or using a flexible endoscope or laryngeal mask, and finally surgical interventions including cricothyrotomy or tracheotomy.
