Early (< 10 min): Cardiac arrest; anaphylaxis; pulmonary aspiration of gastric content; serious traumatic airway injury; desaturation (SAT < 90%); major hemodynamic instability (MAP < 50, new onset bradycardia < 40 beats/min); or sustained new arrhythmia (causing hemodynamic instability or requiring intervention).

Late (< 24 h): Death; brain damage including stroke; acute myocardial infarction; ICU admission; re-intubation; respiratory failure (oxygen demand > 5 l/min or requiring interventions aside from oxygen therapy); intraoperative awareness; pneumonia; dental injury; sore throat; or hoarseness.

Defined as failed tracheal tube delivery after the first attempt of introduction of the video laryngoscope into the patient's mouth.

Tracheal tube delivery is defined as failed when the tube is retracted out of the patient's mouth, OR the video laryngoscope has to be retracted out of the patient's mouth, OR there is a shift in intubation equipment OR a change in the person performing the intubation management OR the intubation is abandoned.

The patient's experience of the treatment using a numeric rating scale (NRS 0 - 10 (0 = very dissatisfied; 10 = very satisfied))

Defined as: respiratory failure, major adverse cardiac (in-hospital all-cause death, acute myocardial infarction (AMI) both acute ST elevation MI and non-ST elevation MI, complete heart block, cardiogenic shock, cardiac arrhythmia and cardiac arrest), pneumonia, acute kidney injury, admission to ICU and cerebrovascular event (ischemic stroke including transient cerebral ischemia).

Minutes the patient is at the Post-Anaesthesia Care Unit.

The intubation is abandoned

The first attempt is defined as an attempt (successful or not) at tracheal tube delivery after the first introduction of the video laryngoscope into the patient's mouth.

Additionally attempts are defined as: when the tube has to be re-introduced into the patient's mouth, OR the videolaryngoscopy has to be re-introduced into the patient mouth, OR there is a shift in intubation equipment OR a change in the person performing the intubation management

Categorised as closed, intermediate or open

Rescue medication is defined as: An additional bolus of neuromuscular blocking agents, or bolus of opioid or propofol or other anesthetics according to the discretion of the attending anaesthesiologist in order to solve insufficient airway management conditions.

SAT < 80%

Defined as any vasoactive substance, e.g. epinephrine, noradrenaline, phenylephrine, ephedrine administrated as a response to severe hypotension or bradycardia after induction.
