Comparison Between Fekry and Air-Q Intubating Airways as Conduit for Fibreoptic Endotracheal Intubation in Adult Patients

"Both groups:~Grade 1: Split airway provides an unobstructed path for bronchoscope from mouth to glottis.~Grade 2: Tongue rests against posterior pharyngeal wall causing partial obstruction to bronchoscope.~Grade 3: Epiglottis rests against posterior pharyngeal wall causing partial obstruction to bronchoscope.~Grade 4: Tongue and epiglottis rest against posterior pharyngeal wall, both causing partial obstruction to bronchoscope.~Grade 5: Tongue rests against posterior pharyngeal wall causing total obstruction to bronchoscope (failure).~Grade 6: Epiglottis rests against posterior pharyngeal wall causing total obstruction to bronchoscope (failure)"
