This study aims to train an AI for video-directed endotracheal intubation (VITION) to recognise the anatomical structures of the upper airway during video-directed endotracheal intubations.
Study design The VITION study protocol describes the design of a prospective, observational study. Inclusion will commence in 2023 at the anesthesia and intensive care departments in the Capital Region of Denmark. Participants Patients across all ages are eligible for inclusion if they are undergoing video-directed oral or nasal endotracheal intubation. Exclusion criteria Patients are excluded if they adhere to one of the exclusion criteria: * Upper airway malformations (e.g., laryngomalacia, vocal cord paralysis, and subglottic stenosis17,18). * Failed attempt by video laryngoscopy due to malfunctioning equipment. * Missing or corrupted video recording. * Informed consent is not obtained from the participants or participants' parents / legal guardians. Interventions and comparisons This prospective, observational study will have no interventions or comparisons. Primary objective The primary objective is to characterize anatomical landmarks and performances of intubations in a large and diverse pool of clinicians and patients.
Study Type
OBSERVATIONAL
Enrollment
10,000
There will be no intervention in this prospective observational cohort study. Endotracheal intubation is already used to secure the airway by placing an endotracheal tube into the trachea via the oral or nasal route. Indications include the need for airway control during general anaesthesia, mechanical ventilation, resuscitation, and various forms of acute respiratory distress.

Time consumption of the course.
A course is defined as one method for intubation (i.e., the same airway device, approach, and medication regimen). Many attempts by multiple providers are allowed within a given course as long as all attempts are made using the same method.
Time frame: During the procedure.
Number of attempts.
The number of attempts (one, two, and three or more).
Time frame: During the procedure.

Successful endotracheal intubation.
Successful endotracheal intubation is defined as correct endotracheal tube placement in the trachea confirmed by chest rise, auscultation, waveform monitor for end-tidal CO2, and/or chest radiograph in first, second, or three attempts.10,19 First-attempt success is defined according to previous studies as successful intubation on the first attempt by the first provider. Success within two attempts is defined as successful intubation on the second attempt by the same provider. Success within 3 attempts is defined as successful intubation on any attempt by the same provider.
Time frame: During the procedure.
Overall course success.
Overall course success is defined as successful intubation by any provider on any attempt within that course.
Time frame: During the procedure.
Severe oxygen desaturations
Severe oxygen desaturations are defined according to previous studies as a 20% or more decrease in oxygen saturation from the highest level immediately before the first attempt.
Time frame: During the procedure.
Non-severe TIAEs
Non-severe TIAEs: Oesophageal intubation with immediate recognition, dysrhythmia including any duration of heart rate \<60 beats per minute without chest compressions, main-stem bronchial intubation, emesis without aspiration, pain or agitation requiring additional medications causing a delay in intubation, epistaxis, lip trauma, dental injury, medication error, and hypertension.
Time frame: 72 hours after the procedure
Severe TIAEs
Severe TIAEs: Cardiac arrest requiring chest compressions, oesophageal intubation with delayed recognition (defined as placement of the endotracheal tube into the oesophagus or hypopharynx with clinical deterioration, e.g., desaturation, before removal of the misplaced tube), emesis with aspiration, hypotension requiring therapy, laryngospasm, pneumothorax or pneumo-mediastinum, and direct airway injury (e.g., vocal cord injury, laryngeal injury, tracheal injury, false passage creation).
Time frame: 72 hours after the procedure
