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.

Difficult videolaryngoscopic intubation
Defined as a difficult airway alert issued by the airway operator following videolaryngoscopy
Time frame: 1 hour
Multiple laryngoscopy attempts
More than one laryngoscopy attempt required until airway established
Time frame: 1 hour
Multiple tracheal intubation attempts
More than one tracheal intubation attempt until airway established
Time frame: 1 hour
First attempt success rate
Percentage of successful intubations with one attempt at laryngoscopy and intubation
Time frame: 1 hour
Percentage of glottic opening (POGO) score
Best glottic view obtained during videolaryngoscopy assessed with the POGO score (%)
Time frame: 1 hour
Quality of glottic visualization
Subjective ratings on visual analog scales (0 to 100; higher values indicate better glottic view)
Time frame: 1 hour
Tracheal intubation time
Time until successful tracheal intubation
Time frame: 1 hour
Airway-related adverse events

Time frame: 1 hour
Difficulty of videolaryngoscopic tracheal intubation
Difficulty of videolaryngoscopic tracheal intubation assessed by the PeDiAC score (0-8; higher values indicate increased difficulty)
