Brief Summary:
Using a combination of the video-laryngoscope with the disposable fiber-optic bronchoscope (aScope III) is a feasible way to facilitate successful intubation in a timely manner, in patients with predicted difficult airway due to tumors in the oral cavity, pharynx or larynx To test the hypothesis that combination of video-laryngoscope with the fiber-optic bronchoscope is superior to video-laryngoscope alone for intubation of patients with oral cavity, pharyngeal or laryngeal pathologies undergoing surgery

Condition or disease Intervention/treatment Phase
Intubation; Difficult Device: King Vision video-laryngoscope with #3 disposable blade and endotracheal tube stylet Device: fiberoptic bronchoscope aScope III Not Applicable

Arm Intervention/treatment
Active Comparator: control group videolaryngoscope/preformed stylet
The control group will intubate using the video-laryngoscope / pre formed stylet. Will convert to using video-laryngoscope and fiber-optic bronchoscope (aScope III) if failure to intubate occurs
 Device: King Vision video-laryngoscope with #3 disposable blade and endotracheal tube stylet
intubation using King Vision video-laryngoscope with #3 disposable blade with stylet convert to intubation with video-laryngoscope and fiber-optic bronchoscope bronchoscope (aScope III) for failure to intubate after three attempts
Other Name: Ambu aScope III

Device: fiberoptic bronchoscope aScope III
Intubation using the videolaryngoscope/fiberoptic bronchoscope (aScope III)
Other Name: aScope III by Ambu
Experimental: Interventional Group videolaryngoscope/fibeoptic bronch
The interventional group will Intubate using the video-laryngoscope and the fiber-optic bronchoscope (aScope III)
 Device: fiberoptic bronchoscope aScope III
Intubation using the videolaryngoscope/fiberoptic bronchoscope (aScope III)
Other Name: aScope III by Ambu


Outcome Measures

Primary Outcome Measures :
  1. Time to successful intubation [ Time Frame: From time full relaxation is achieved to time the patients is successfully intubated confirmed by breath sounds over a period of up to ten minutes ]
    measured in seconds


Secondary Outcome Measures :
  1. Conversion from control group to intervention group [ Time Frame: From the time full relaxation is achieved until the subject is successfully intubated confirmed by breath sounds over a period of up to ten minutes ]
    Number of subjects randomized to control group who require to be treated with the method of the intervention group

  2. Number of intubation attempts until successful [ Time Frame: From the time full relaxation is achieved until the time the subject is intubated; confirmed with breath sounds over a period of up to ten minutes ]
    whole numbers of attempts
