Brief Summary:
Following informed consent, patients will be randomly assigned to oral fiberoptic intubation or to oral intubation using the GlideScope Video Laryngoscope. Following the induction of general anesthesia a sealed envelope would be opened to reveal the technique to be used. A stop watch will be started at the beginning of the procedure. At the completion of intubation the stop watch will be stopped and the time recorded along with other data. Based on a sample size estimation process, it is the investigators plan to study fifty patients. The two techniques will be compared in terms of the average time needed to place the endotracheal tube and studied using a two-sided T-Test with a significance level of 0.05. To ensure comparability between the two methods, all intubators will be required to have at experienced at least 10 uses of the GlideScope and 10 uses with fiberoptic intubation.

Outcome Measures

Primary Outcome Measures :
  1. Time to Intubation (TTI) as Measured in Seconds [ Time Frame: from start of intubation to successfully intubated up to 100 seconds ]
    Time from insertion of either the GlideScope or in the case of fibreoptic intubation, a Williams airway (SunMed, Largo, FL, USA) into the mouth, to the time when end-tidal PCO2 exceeded 2.7 kPa (20 mmHg).


Secondary Outcome Measures :
  1. Intubation Difficulty Score [ Time Frame: from start of intubation to successfully intubated ]
    Intubation difficulty score is a 100-mm-long visual analogue scale (100 mm = extremely difficult);

  2. Successful Intubation on 1st Attempt [ Time Frame: from start of first intubation to end of first intubation attempt ]
  3. Occurrence of Hypoxaemia [ Time Frame: at 1 min prior to intubation, intubation, and 2, 4, 6, 8, and 10 min after ]
    Arterial oxygen saturation was recorded at 1 min prior to intubation, intubation, and 2, 4, 6, 8, and 10 min after; hypoxaemia was defined as occurrence of arterial oxygen saturation <90% at any of the above measurements.

  4. Trace Bleeding [ Time Frame: Right after intubation ]
    Trace bleeding is a binary outcome: yes or no, which is determined based on amount of post-intubation bleeding present in the suction tube

  5. Sore Throat Grade [ Time Frame: On the first postoperative day ]
  6. Number of Intubation Attempts [ Time Frame: from start of intubation to successfully intubated ]
