A comparison between the GlideScope <sup>®</sup> Video Laryngoscope and direct laryngoscope in paediatric patients with difficult airways – a pilot study
Bibliographic record
Abstract
The GlideScope Video Laryngoscope may improve the view seen at laryngoscopy in adults who have a difficult airway. Manikin studies and case reports suggest it may also be useful in children, although prospective studies are limited in number. We hypothesised that the paediatric GlideScope will result in an improved view seen at laryngoscopy in children with a known difficult airway, compared to direct laryngoscopy. Eighteen children with a history of difficult or failed intubation were prospectively recruited. After inhalational induction, each patient had laryngoscopy performed using a standard blade followed by GlideScope videolaryngoscopy. The GlideScope yielded a significantly improved laryngoscopic view, both with (p = 0.003) and without (p = 0.004) laryngeal pressure. The mean (SD) time taken to achieve the optimal view was 20 (8)s using conventional laryngoscopy and 26 (22)s using the GlideScope (p = 0.5). The GlideScope significantly improves the laryngoscopic view obtained in children with a difficult airway.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
