About this study
Endotracheal intubation requires significant training and expertise. This experience can be quite stressful for novice users. To accelerate the learning curve of newly enrolled trainees to assess and secure airway, the investigators propose supplementing current training techniques with access to an airway video library consisting of real- life clinical videos of airway and endotracheal intubations.
Read the detailed description
Timely and correctly performed endotracheal intubation is important. It can be stressful especially among beginners and requires significant expertise. Studies suggest that endotracheal intubation success rates are below 50% for the first 10 intubations among novices and the learning curve of laryngoscopy does not plateau above a 90% success rate until a mean of 57 attempts. Although simulation, which is currently the mainstay of training for airway management help orient a novice user, it is siloed from the actual experience.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Airway Video Library TrainingBehavioural
A video airway library consisting of real-life clinical videos of laryngoscopy and endotracheal intubation was developed by the study investigators. This library consists of video clips of normal and easy airways, pediatric airways as well as pathological or difficult airways that is devoid of patient identifying data. The participants of the study group will be exposed to the video library by two learning sessions. Each learning session consists of 1 hour of interactive \& immersive learning of 30 airway videos. At the end of the session, the participants will be oriented to the airway and identify key airway structures, learn to troubleshoot and navigate difficult anatomy, optimize visualization, and use accessory airway equipment.
Conventional Airway TrainingBehavioural
The endotracheal intubation training Anesthesiology students currently receive routinely as part of their education.
| Study group | Role | What they receive |
|---|---|---|
| Group A | At the beginning of Phase 1, participants from Group A will be exposed to the video airway library in addition to the conventional airway training. At the beginning of Phase 2, participants will continue with conventional airway training only. Each phase will last for 1 month. Receives: Behavioral: Airway Video Library Training; Behavioral: Conventional Airway Training | |
| Group B | At the beginning of Phase 1, participants from Group B will be exposed to the conventional airway training only. At the beginning of Phase 2, the participants in Group B will be exposed to the video airway library. Each phase will last for 1 month. Receives: Behavioral: Airway Video Library Training; Behavioral: Conventional Airway Training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Attempts to Successful Intubation
Intubation success rate will be reported in number of attempts, where lower values equate to greater success. Supervising staff report success rates.
Measured: 2 months
Time for Successful Intubation
Time to successful intubation will be measured in seconds as reported by supervising staff.
Measured: 2 months
Difficulty Level of Intubation as Assessed by Intubation Difficulty Scale
The supervising staff fills out a questionnaire that assesses the technical skill of laryngoscopy and the complexity of intubation as per the Intubation Difficulty Scale (IDS). Those with and without exposure to the video library will be compared. The IDS is a sum of 7 parameters. The sum value of 0 indicates easy intubation, 1-5 indicates slight difficulty, and values greater than 5 indicate moderate to high difficulty.
Measured: 2 months
Secondary outcomes (1)
Stress Level as Assessed by Ottawa Mood Scales
The participant fills in the Stress Scale item of the Ottawa Mood Scales with Likert scale response to reflect the stress they experienced surrounding endotracheal intubation. The scale ranges from 0 to 10, where higher scores indicate greater stress. Those with and without exposure to the video library will be compared.
Measured: 2 months
