Details of the data collection forms regarding airway management

Airway management
Items	Contents for reporting
Value of SpO2 at the initiation of airway management	%
Lowest value of SpO2 during airway management	%
Times of attempts to secure the airway per one airway securing procedure	Number of times
Reasons to start securing the airway	Scheduled procedure, airway concerns after extubation, desaturation, apnoea, dislodgement of airway devices, obstruction of airway devices, avoiding airway stimulation by airway devices, inadequate ventilation with excessive air-leakage, prevention of aspiration, laryngeal oedema, laryngospasm, bronchospasm, airway trauma, atelectasis formation, pulmonary oedema, pulmonary secretion removal, pneumothorax/pneumomediastinum, unstable haemodynamics, others.
Medications administered during airway management	Sevoflurane, desflurane, nitrous oxide, fentanyl, morphine, remifentanil, rocuronium, vecuronium, suxamethonium, sugammadex, midazolam, propofol, thiopental, remimazolam, ketamine, dexmedetomidine atropine, epinephrine, lidocaine (intratracheal, intravenous).
Provider’s assigned number	Number
Success of securing airway	Success, failure (inadequate exposure of glottic view, unstable haemodynamics, upper airway obstruction/oxygenation failure, unable to insert airway device (proximal or distal site of the vocal cords), excessive air-leakage, oversized airway device, others).
Provider’s training level	Residents (junior or senior), fellow (anaesthesia or other), board-certified anaesthesiologists (percentage of paediatric cases among the whole experienced cases over the last 1 year; ≥80%, 50–80%, <50%, other board-certified physicians (emergency medicine, intensive care medicine, others), others (eg, nurse anaesthetists).
Postgraduate year of provider	1, 2, 3, 4, 5, 6–9, ≥10 years
Route of securing the airway	Oral, nasal, tracheostomy, others
Device to secure the airway	Laryngoscope, supraglottic airway devices, video laryngoscope (with or without guide), stylet, non-directed laryngoscope without video monitor, gum elastic bougie/tube exchanger, flex bronchoscope, tracheostomy tube, surgical airway secure, tracheal intubation via supraglottic airway devices.
Size of airway device	Number
Types of a tracheal tube	Normal, armoured, RAE, double-lumen, others
Cuffed tracheal tube	Yes/no
Performing cricoid pressure	Yes/no
Performing external laryngeal manipulation	Yes/no
Performing apnoeic oxygenation	Yes/no
POGO score	%
Complications during securing airway	None, cardiac arrest (survive, death), laryngospasm, upper airway obstruction, severe cough, endobronchial intubation, oesophageal intubation, vomiting, hypotension, hypertension, tooth injury, pneumothorax, mediastinal emphysema, bronchospasm, atelectasis, pulmonary oedema, stridor, airway trauma, arrhythmia, agitation, dislodgement of airway securing devices, others.
Treatment for complications during securing airway	None, sedatives, muscle relaxants, ventilatory support with tracheal tube, bronchodilator, intratracheal suctioning, inhalational epinephrine, intravenous epinephrine, intravenous steroid, atropine, surgical airway secure, cardioversion/defibrillation, inotropes/vasopressors, bolus infusion, anti-arrhythmic medications, cardiopulmonary resuscitation, extracorporeal membrane oxygenation, reversal medications, diuretics, admission to intensive care unit, others.

POGO, percentage of glottic opening; RAE, right angle endotracheal tubes; SpO₂, peripheral capillary oxygenation saturation.
