An Airway which Facilitates intubation with a Fiberoptic Laryngoscope

Fiberoptic laryngoscope (FL) is often used when there is the probability of difficult intubation. In addition to facilitating intubation it also reduces the risk of laryngoscope-induced complications such as trauma and airway edema. It is mostly utilized when the patient is awake and under the influence of local anesthesia and mild sedation; this is because by reserving spontaneous respiration, besides maintaining adequate oxygenation it facilitates fiberoptic laryngoscopy and intubation(1).
In some cases due to the lack of patient cooperation or discovering a difficulty in intubation during laryngoscopy, it is done under general anesthesia. In such conditions because of muscular relaxation and tongue retraction, in addition to the risk of hypoxia during laryngoscopy, working with FL becomes harder and will not give a clear visual pathway; especially when oral intubation is the case.
In such circumstances in order to lift the tongue and prepare a clear visual pathway it is better to use an oropharyngeal airway  (such as Williams, Ovassapian or Bermann II) or an intubating LMA. In this aspect we introduce a new type of airway which facilitates fiberoptic laryngoscopy and endotracheal intubation. This airway is a modified type of the common oropharyngeal
airway, which its right side is dissected (Fig1). In an anesthetized patient after inserting the airway into his mouth and fixing it in the middle line, the fiberoptic laryngoscope is guided downwards through its tube (Fig 2). After seeing the terminal section of the airway it is advanced 1-2 cm further till the glottis comes into view, passes by it and reaches the carina; then the fiberoptic laryngoscope cord is released from the right side of the airway which has been dissected (Fig 3) and the airway is taken out of the patient's mouth.
