difficult airway


Also found in: Dictionary, Thesaurus, Encyclopedia.
A clinical situation in which a conventionally trained anesthesiologist experiences difficulty with face mask ventilation of the upper airway, difficulty with tracheal intubation, or both. The difficult airway represents a complex interaction between patient factors, the clinical setting, and the skills of the practitioner

difficult airway

An airway that is challenging or impossible to intubate. Intubation is increasingly difficult in: older patients, patients with head or neck trauma, obese patients, and patients with craniofacial abnormalities.
