Health Condition(s) or Problem(s) studied

Health Condition 1: C229- Malignant neoplasm of liver, not specified as primary or secondary

Intervention(s)

Intervention1: McGrath videolaryngoscope: The McGrath videolaryngoscope has a small LCD screen, a single choice of blade (with three different length settings), and an acrylic cover with a 60 degree angulation to provide an indirect view of the glottis.
Control Intervention1: Macintosh laryngoscope: In patients whose airway is not predicted to be difficult pre-operatively, the standard technique of intubation is to use a Macintosh laryngoscope to visualize the glottic opening and to guide the nasotracheal tube into the glottis using Magills forceps.

Primary Outcome(s)

To compare time taken for intubation using the two blades.Timepoint: Preoperatively for nasotracheal intubation

Secondary Outcome(s)

â?¢To compare success rates for intubation in the two groups of patients.

â?¢To compare difficulty level during intubation using Adnet scale

Timepoint: Preoperatively for nasotracheal intubation
