Abstract
Difficulty in airway management is a clinically important complication, which can lead to morbidity and mortality. An emergency surgical airway is necessary when noninvasive techniques fail and severe hypoxemia develops. To reduce this risk, knowledge, careful assessment, good planning, and judgment, as well as the use of a wide range of techniques and devices, are required. Airway assessment helps to anticipate the difficult airway, and a set of devices should be available for proper management in difficult cases. Maintenance of oxygenation is a priority, and preoxygenation should be performed before any attempt at airway management. Bag mask ventilation and direct laryngoscopy require careful positioning of the patient and an array of basic skills on the part of the operator. The laryngeal mask airway is an important rescue device in the “cannot intubate, cannot ventilate” situation. Recent advances have led to the development of videolaryngoscopes that facilitate the indirect visualization of the larynx, with minimal mouth opening and head extension. Difficult-airway algorithms have been developed to provide a structured response to this life-threatening situation.
