Ovassapian VS Fekry Airways
Conditions
Brief summary
The fibreoptic bronchoscope remains one of the most important methods of intubating patients particularly when there is difficulty with intubation Facilitating fiberoptic oropharyngeal intubation procedure, specific airways have been devised to push the tongue anteriorly to clear a passage for the fibrescope into the trachea. Of these airways Ovassapian Fibreoptic Intubating Airway (Kendall, Argyle, New York, New York, USA) and Fekry Oral Intubating Airway (Ameco Tech, Cairo, Egypt).
Detailed description
Ovassapian Fibreoptic Intubating Airway : The Ovassapian Fibreoptic Intubating Airway has a flat lingual surface that widens distally. This provides better retraction of the tongue to prevent it and the soft tissues of the anterior pharyngeal wall from herniating around the side of the airway. The airway has a pair of vertical sidewalls and two pairs of curved guide walls at its proximal section. These walls are separated by a gap which allows removal of the airway after intubation has been completed. Fekry airway: ● It has two parts are: Airway body& Special connector 1. Airway body consists of: 1. Flange → it is the buccal end it is 7 cm wide to prevent it from moving deeper into mouth & may also serve to fix airway in place. 2. Bite Portion → it is straight & fits between teeth &oral cavity. 3. Oral straight part → open anterior lingual part; it varies in length according to size 4. Pharyngeal curved part → extends backwards to correspond the shape oropharynx and ends below laryngeal inlet. 2. The connector: it is a special type (two sizes: adult and pediatric) can attach to all ventilating machines& it has a teeth rest act as a bite block.

Masking description
Randomization will be done using computer generated number and concealed using sequentially numbered, sealed opaque envelope.
Intervention model description
Either the Fekry Oral Airway Intubator (Ameco Tech, Cairo, Egypt) or the Ovassapian Fibreoptic Intubating Airway (Kendall Sheridan, Argyle, NY) will be inserted into the mouth in random order, and the patient's lungs ventilated by bag and facemask with 100% oxygen and 1-1.5% isoflurane. Blinding will be impossible in this study as the operator has to see the airway through the fibrescope in order to perform the assessment. After confirmation of full neuromuscular blockade, a bronchoscope with a preloaded tracheal tube will be then inserted through the airway for bronchoscopic assessment.
