Effect of Airway Video Library on Intubation in Novices

November 21, 2025 updated by: University of Minnesota
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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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. 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

All the anesthesia residents employed by the University of Minnesota (UMMC) and part of the Fairview system comprise the study population. The clinic/hospitals these residents (CA-1 year) are affiliated with include University of Minnesota Medical Center East and West Bank and VA Minneapolis.

Description

Inclusion Criteria:

  • Incoming anesthesia resident (CA-1 year)

Exclusion Criteria:

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
Behavioral: Airway Video Library Training
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.
Behavioral: Conventional Airway Training
The endotracheal intubation training Anesthesiology students currently receive routinely as part of their education.
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.
Behavioral: Airway Video Library Training

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Attempts to Successful Intubation
Time Frame: 2 months
Intubation success rate will be reported in number of attempts, where lower values equate to greater success. Supervising staff report success rates.
2 months
Time for Successful Intubation
Time Frame: 2 months
Time to successful intubation will be measured in seconds as reported by supervising staff.
2 months
Difficulty Level of Intubation as Assessed by Intubation Difficulty Scale
Time Frame: 2 months
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.
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Stress Level as Assessed by Ottawa Mood Scales
Time Frame: 2 months
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.
