A randomized comparison the of the air-Q® intubating laryngeal airway and Ambu® AuraGain™ laryngeal mask for controlled ventilation in children

Abstract

Objective: to compare the effectiveness between air-Q® intubating laryngeal airway and Ambu AuraGain laryngeal mask for controlled ventilation in children up to 30kg
Design: Prospective, randomized controlled trial
Setting: Operating theatre of Hospital Universiti Sains Malaysia
Methodology: 64 pediatric patients underwent various short surgical procedures were randomly assigned to receive either an air-Q® or Ambu AuraGain supraglottic airway. Fibreoptic grades of laryngeal view were measured as the primary outcome. The secondary outcomes measured were oropharyngeal leak pressure (OLP), number of attempts, time of successful insertion, quality of airway during placement and maintenance of anesthesia, hemodynamic parameters, and complications.
Results: air-Q® has more favorable fiberoptic grades of view compared to the Ambu AuraGain (p = 0.047). OLP is significantly higher in air-Q® compared to Ambu AuraGain (19.41 ± 1.19 cmH₂O vs 17.56 ± 1.52 cmH₂O, p ≤ 0.001). There were no differences in terms of number of attempt, time of successful insertion, quality of airway during placement and maintenance of anesthesia and complications.

Conclusion: Air-Q^® offers more clinical advantages than Ambu AuraGain for controlled ventilation in pediatric patients as it provides higher airway sealing pressure and better fiberoptic grade of laryngeal view.
