Randomized Controlled Trial Comparative StudyComparison of performance and efficacy of air-Q intubating laryngeal airway and flexible laryngeal mask airway in anesthetized and paralyzed infants and children.
Flexible laryngeal mask airway is a commonly used supraglotic airway device (SAD) during ophthalmic surgeries. Air-Q intubating laryngeal airway (ILA) is a newer SAD used as primary airway device and as a conduit for intubation as well. Available literature shows that air-Q performs equal or better than other SADs in children and adults. However, limited data is available using air-Q in infants and small children <10 kg. So, our aim was ‘To compare the performance and efficacy of these two devices in infants and small children’. Our hypothesis is that air-Q due to its improved cuff design will yield better airway seal pressures and improved laryngeal alignment as compared to flexible laryngeal mask airway. ⋯ We conclude that air-Q is superior to flexible laryngeal mask airway in providing higher airway sealing pressures and better FO grade of laryngeal view in infants and children.

Randomized Controlled Trial Comparative StudyThe randomized crossover comparison of airway sealing with the laryngeal mask airway Supreme(™) at three different intracuff pressures in children.
An intracuff pressure of 80 cm H2 O in the adult-sized laryngeal mask airway Supreme has been recommended to obtain a higher oropharyngeal leak pressure (OLP). However, the intracuff pressure for the higher OLP in the pediatric laryngeal mask airway Supreme could be different from that in the adult-sized laryngeal mask airway Supreme. Thus, we measured and compared OLP at three intracuff pressures of 40, 60, and 80 cm H2 O in the pediatric laryngeal mask airway Supreme. ⋯ Our results suggest that the use of an intracuff pressure of 60 cm H2 O in pediatric laryngeal mask airway Supreme provides a higher OLP compared with 40 cm H2 O.
