Brief Summary

The goal of this clinical trial is to learn if performance of a channelled blade Astra-Vue videolaryngoscope compared to non channelled hyperangulated C-MAC D-blade videolaryngoscope(Karl Storz, Tuttlingen, Germany) in airway management among adults undergoing elective surgery under general anesthesia. The main primary outcomes measured is the overall time taken to intubation, secondary measures includes the first attempt success rate, ease with intubation and associated complication Participants are of adults who planned for elective or semi emergency surgery under general anesthesia. They will be screened and recruited with informed and written consent. Intubation information will be collected

Conditions

Airway Management

Keywords

intubation; videolaryngoscope; first attempt success rate; ease of intubation; time to intubation

Outcome Measures

Primary Outcomes (1)

• Total Time to intubation

  time from insertion of laryngoscope blade through incisor teeth to visualization of Endotracheal tube into trachea, measured in seconds

  During the intubation procedure (within minutes after induction of general anaesthesia)

Secondary Outcomes (5)

• First attempt success rate

  During the intubation procedure(within minutes after induction of general anaesthesia)

• Time to Glottic Visualization

  During the intubation procedure(within minutes after induction of general anaesthesia)

• Ease of intubation

  During the intubation procedure an immediate post-intubation period (within minutes after induction of general anaesthesia)

• Change in Mean Arterial Pressure from baseline

  Baseline taken during induction prior to intubation, second reading repeated at 1 minute after successful intubation

• Change in Heart rate from baseline

  Baseline measured prior to intubation, second reading repeat at 1 minute post intubation
