Intervention(s)

CMAC video laryngoscope is having same conventional Macintosh Laryngoscope blade, but with a camera. Essentially it will be indirect view in contrast to direct view by Macintosh Laryngoscope. The laryngoscopy will be done by single experienced( in CMAC) anesthetist of consultant grade
Intubation difficulty scale score is recorded . Which reaches higher score if there is change in hands, device or technique. Failed intubation in one technique yield infinite score ( as per Intubation difficiculty scale scoring, 0: difficulty,8 (infinite): impossible to intubate) )and suitable alternative will be employed in securing intubation or ventilation.
Manual In line Axial Stabilisation(MIAS) is essentially proven step in preventing the further damage in C-spine injury . A trained anesthetist will be employing MIAS manouvere before intubation attempts.Essentially MIAS involves a trained person stabilizing the head and neck by crouching beside the intubator with hands placed on the patient’s mastoid processes or cradling the occiput giving sufficient counter pressure to prevent neck movements during laryngoscopy.

Primary Outcome(s)

Intubation Difficulty Scale Score[The IDS score will be recorded by the laryngoscopist after the successful intubation with apperance of ETCO2 tracings]

Secondary Outcome(s)

Composite Outcome
Hemodynamic parameters Heart rate, Systolic blood pressure, Diastolic pressure and Mean arterial pressure.
The above-said variables are measured using multiparameter which has Pulse oximetry, Non invasive automated bloodpressure, ECG [recorded at pre induction, pre intubation , post intubation and 3 minutes post intubation]
