Abstract
Purpose
To assess epiglottic position after laryngeal mask airway (LMA) insertion with or without the use of a laryngoscope.
Methods
A double-blind randomized study. In 48 children an LMA (#2 for 6–20 kg, #2.5 for 20–30 kg) was inserted either blindly or with the help of a laryngoscope and its position assessed using fibreoptic endoscopy.
Results
An unobstructed view of the glottis, as assessed by fibrescope, was observed in 10 of 25 patients in the laryngoscope group, but only in 1 of 22 patients in the blind insertion group (P = 0.005).
Conclusion
This technique offers an alternative when the standard technique has failed, or when LMA insertion precedes bronchoscopy or intubation via the laryngeal mask.
Résumé
Objectif
Déterminer la position de l’épiglotte après l’insertion du masque laryngé (ML) avec ou sans laryngoscope.
Méthode
Etude aléatoire et en double aveugle. Chez 48 enfants, un masque laryngé (Nℴ2 pour les 6 à 20 kg, Nℴ2,5 pour les 20 à 30 kg) a été inséré à l’aveugle ou avec un laryngoscope et sa position vérifiée par fibroscopie.
Résultats
La visualisation non obstruée de la glotte, vérifiée par fibroscopie, a été constatée chez 10 des 25 patients du groupe laryngoscopie, mais chez seulement un des 22 patients dans le groupe intubation à l’aveugle (P = 0,005).
Conclusion
Cette technique constitue une solution de rechange quand la technique standard a échoué ou quand l’insertion du ML précède une bronchoscopie ou une intubalion à travers un ML.
