An observational study of Intubation, Pediatric and Intubation; Difficult or Failed, run by Universitätsklinikum Hamburg-Eppendorf at 1 site in Germany.
Trial 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. Read more about this study

About this study
Official title: External Validation of the POGO Score for Classification of Videolaryngoscopic Intubation in Children and Comparison With the Quality of the Glottic View Rated on Visual Analogue Scales - Post-hoc Analysis of the Prospective 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Difficult videolaryngoscopic intubation
Defined as a difficult airway alert issued by the airway operator following videolaryngoscopy
Measured: 1 hour
Secondary outcomes (10)
Multiple laryngoscopy attempts
More than one laryngoscopy attempt required until airway established
Measured: 1 hour
Multiple tracheal intubation attempts
More than one tracheal intubation attempt until airway established
Measured: 1 hour
First attempt success rate
Percentage of successful intubations with one attempt at laryngoscopy and intubation
Measured: 1 hour
Percentage of glottic opening (POGO) score
Best glottic view obtained during videolaryngoscopy assessed with the POGO score (%)
Measured: 1 hour
Quality of glottic visualization
Subjective ratings on visual analog scales (0 to 100; higher values indicate better glottic view)
Measured: 1 hour
Tracheal intubation time
Time until successful tracheal intubation
Measured: 1 hour
Airway-related adverse events
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
Measured: 1 hour
Difficulty of videolaryngoscopic tracheal intubation
Difficulty of videolaryngoscopic tracheal intubation assessed by the PeDiAC score (0-8; higher values indicate increased difficulty)
Measured: 1 hour
Severe hypoxaemia
Oxygen saturation < 70% or hypoxaemia-related bradycardia
Measured: 1 hour
Prolonged tracheal intubation
Tracheal intubation time > 90 sec
Measured: 1 hour
