Overview

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

This randomized controlled trial aims to compare the performance of a channelled videolaryngoscope (AstraVue videolaryngoscope) with a non-channelled hyperangulated videolaryngoscope (C-MAC™ D-Blade videolaryngoscope, Karl Storz, Tuttlingen, Germany) in adult patients undergoing elective or semi-emergency surgery under general anaesthesia requiring endotracheal intubation. Participants will be randomly assigned to intubation using either the channelled AstraVue videolaryngoscope or the non-channelled C-MAC D-Blade videolaryngoscope. Standard anaesthesia induction protocols will be followed. The primary outcome is the total time to successful intubation. Secondary outcomes include time to glottic visualization, time from glottic visualization to intubation, first-attempt success rate, number of attempts, need for external laryngeal manipulation, haemodynamic responses, and intubation-related complications. Data will be collected prospectively during the peri-intubation period. The study aims to evaluate whether the channelled design improves intubation efficiency and success compared to the non-channelled videolaryngoscope.

Outcomes

Primary Outcomes

Total Time to intubation

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

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

Secondary Outcomes

First attempt success rate

Successful endotracheal intubation on the first attempt, measured as a proportion of total intubations(%)

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

Time to Glottic Visualization

time from insertion of laryngoscope blade to visualization of glottis, measured in seconds

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

Ease of intubation

Ease of intubation assessed using a modified Intubation Difficulty Scale (IDS), which includes parameters such as number of attempts, additional operators, alternative techniques, lifting force, external laryngeal pressure, vocal cord position, and intubation difficulty. The total score ranges from 0 to ≥5, where a score of 0 classified as easy, 1 to 5 classified as slight difficulty, and \>5 as moderate to major difficulty, generally higher score means increasing difficulty

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

Change in Mean Arterial Pressure from baseline

Change in Mean arterial pressure measured at 1 minute after successful intubation, expressed as percentage change from baseline value

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

Change in Heart rate from baseline

Change in heart rate measured at 1 minute after succesful intubation, expressed as percentage change from baseline value

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