Validation of the POGO Score for Classification of Videolaryngoscopy in Children - Post-hoc Analysis of the PeDiAC Study

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.

Treatment and study plan

Primary outcomes

  1. Difficult videolaryngoscopic intubation

    Time frame: 1 hour

    Defined as a difficult airway alert issued by the airway operator following videolaryngoscopy

Secondary outcomes

  1. Multiple laryngoscopy attempts

    Time frame: 1 hour

    More than one laryngoscopy attempt required until airway established

  2. Multiple tracheal intubation attempts

    Time frame: 1 hour

    More than one tracheal intubation attempt until airway established

  3. First attempt success rate

    Time frame: 1 hour

    Percentage of successful intubations with one attempt at laryngoscopy and intubation

  4. Percentage of glottic opening (POGO) score

    Time frame: 1 hour

    Best glottic view obtained during videolaryngoscopy assessed with the POGO score (%)

  5. Quality of glottic visualization

    Time frame: 1 hour

    Subjective ratings on visual analog scales (0 to 100; higher values indicate better glottic view)

  6. Tracheal intubation time

    Time frame: 1 hour

    Time until successful tracheal intubation

  7. Airway-related adverse events

    Time frame: 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

  8. Difficulty of videolaryngoscopic tracheal intubation

    Time frame: 1 hour

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

  9. Severe hypoxaemia

    Time frame: 1 hour

    Oxygen saturation < 70% or hypoxaemia-related bradycardia

  10. Prolonged tracheal intubation

    Time frame: 1 hour

    Tracheal intubation time > 90 sec
