Channelled Blade Versus Non-Channelled Videolaryngoscope

2026年5月4日 更新者:Yeoh Wei Yen、University of Malaya

Comparative Study of the Channelled Blade Astra-Vue Videolaryngoscope and the Non-Channelled CMAC D-Blade Videolaryngoscope in Airway Management: A Randomized Controlled Trial

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

研究概览

详细说明

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.

主要结果指标

结果测量
措施说明
大体时间
Total Time to intubation
大体时间:During the intubation procedure (within minutes after induction of general anaesthesia)
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)

次要结果测量

结果测量
措施说明
大体时间
First attempt success rate
大体时间:During the intubation procedure(within minutes after induction of general anaesthesia)
Successful endotracheal intubation on the first attempt, measured as a proportion of total intubations(%)
During the intubation procedure(within minutes after induction of general anaesthesia)
Time to Glottic Visualization
大体时间:During the intubation procedure(within minutes after induction of general anaesthesia)
time from insertion of laryngoscope blade to visualization of glottis, measured in seconds
During the intubation procedure(within minutes after induction of general anaesthesia)
Ease of intubation
大体时间:During the intubation procedure an immediate post-intubation period (within minutes after induction of general anaesthesia)
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
During the intubation procedure an immediate post-intubation period (within minutes after induction of general anaesthesia)
Change in Mean Arterial Pressure from baseline
大体时间:Baseline taken during induction prior to intubation, second reading repeated at 1 minute after successful intubation
Change in Mean arterial pressure measured at 1 minute after successful intubation, expressed as percentage change from baseline value
Baseline taken during induction prior to intubation, second reading repeated at 1 minute after successful intubation
Change in Heart rate from baseline
大体时间:Baseline measured prior to intubation, second reading repeat at 1 minute post intubation
Change in heart rate measured at 1 minute after succesful intubation, expressed as percentage change from baseline value
Baseline measured prior to intubation, second reading repeat at 1 minute post intubation
