Fekry VS the Air-Q Intubating Airways Clinical Trial
Official title:
Comparison Between Fekry and Air-Q Intubating Airways as Conduit for Fibreoptic Endotracheal Intubation in Adult Patients
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 the Air-Q Intubating Laryngeal Airway (Air-Q) (Cookgas, St. Louis, MO, USA)
and Fekry Oral Intubating Airway (Ameco Technology, Cairo, Egypt).
The Air-Q Intubating Laryngeal Airway (Air-Q):
The Air-Q™ Intubating Laryngeal Airway (Air-Q) (Cookgas, St. Louis, MO, USA) is a SAD that
was designed primarily to act as a conduit for the passage of a cuffed tracheal tube during
tracheal intubation (1), Compared with the LMA, the Air-Q has a shorter silicon airway tube
that allows an easy visualization of vocal cords and intubation and removal of the device
after tracheal tube insertion. The device has a removable color coded connector, allows
intubation through the airway tube. The device is also wider, C-curved and has an integrated
bite block which makes it easier to place reinforces the tube and diminishes the need for a
separate bite block, with an elevation ramp that facilitates intubation and directs the tube
toward the laryngeal inlet. It also has a built-up mask for improved seal. All of these
features facilitate the passage of the tracheal tube through the device and into the trachea.
Fekry airway (Oral Intubating Airway; Egyptian Patent 28118):
Several modifications of oropharyngeal airways aiming to allow facilitation of intubation and
easy removal of the airway after placement of ETT.
In Fekry airway, modification of the Williams airway facilitates the airway removal after ETT
insertion without need to remove the international part of the ETT (this reduce risk of ETT
dislodgement during airway removal).
The modification made to the Williams airway is that the roof of the proximal cylindrical
tunnel is opened from its upper part to allow one step insertion of the tube. There is no
need for removal of the tube connector after tube insertion. It allows passage of the suction
catheter and may allow oxygen insufflations through a catheter.
As mastering airway management in difficult cases is an essential job to anesthesiologist, we
think it is important to find an easy adjunct to this hard job.
investigators hypothesized that Fekry airway could offer a better conduit to flexible
fiberoptic intubation rather than the air-Q device, because it needs less experience in how
to use, less intubation time.
