Brief summary

It has been assumed that the percentage of glottic opening (POGO) score might enhance the classification of videolaryngoscopic tracheal intubation by offering a more objective rating of glottic exposure but studies in children are lacking. This post hoc analysis of the prospective observational PeDiAC study aims to investigate, if classifying difficult videolaryngoscopic tracheal intubation with the POGO score is superior to a subjective rating of the quality of the glottic view on visual analogue scales (VAS). Post hoc video analysis will be performed by multiple independent raters. A secondary aim is to determine the diagnostic performance of the POGO and VAS for the prediction of relevant user- and patient-centered outcomes and to assess the inter-rater reliability of the POGO score.

Design outcomes

Primary

Measure	Time frame	Description
Difficult videolaryngoscopic intubation	1 hour	Defined as a difficult airway alert issued by the airway operator following videolaryngoscopy

Secondary

Measure	Time frame	Description
Multiple tracheal intubation attempts	1 hour	More than one tracheal intubation attempt until airway established
First attempt success rate	1 hour	Percentage of successful intubations with one attempt at laryngoscopy and intubation
Percentage of glottic opening (POGO) score	1 hour	Best glottic view obtained during videolaryngoscopy assessed with the POGO score (%)
Quality of glottic visualization	1 hour	Subjective ratings on visual analog scales (0 to 100; higher values indicate better glottic view)
Multiple laryngoscopy attempts	1 hour	More than one laryngoscopy attempt required until airway established
Airway-related adverse events	1 hour	Laryngospasm; bronchospasm; airway, oral, soft tissue or dental trauma; laryngeal swelling or use of corticosteroids to reduce swelling risk; oesophageal intubation; pulmonary aspiration; and severe hypoxaemia
Difficulty of videolaryngoscopic tracheal intubation	1 hour	Difficulty of videolaryngoscopic tracheal intubation assessed by the PeDiAC score (0-8; higher values indicate increased difficulty)
Severe hypoxaemia	1 hour	Oxygen saturation \< 70% or hypoxaemia-related bradycardia
Prolonged tracheal intubation	1 hour	Tracheal intubation time \> 90 sec
Tracheal intubation time	1 hour	Time until successful tracheal intubation
