Design outcomes

Primary

Measure	Time frame
To compare total time of intubation (TTI) using Blockbuster ILMA, King Vision Videolaryngoscope and Flexible Fibreoptic scope with simulated immobilized cervical spine in ASA I and II patients undergoing General Anaesthesia .Timepoint: To compare total time of intubation (TTI) at baseline.	—

Secondary

Measure	Time frame
1. To compare first attempt success rate between the groups. 2. To compare intubation attempts between the groups 3.To compare hemodynamic response to intubation between the groups 4. To compare intraoperative complication like trauma to lips, teeth, mucosa or other soft tissues and post-operative complications like sore throatTimepoint: Hemodynamic response- monitored over 10 minutes post intubation. Monitor post-operative complication over 24 hours.	—
