The purpose of this study is to compare the clinical efficacy of the air-Q ILA-SP with the current standard of care, the LMA Unique in anesthetized non-paralyzed pediatric patients.

The goal for this randomized, non-crossover investigation is to compare a disposable version of the standard LMA, LMA Unique TM,with the air-Q ILA-SP in pediatric patients. Oropharyngeal leak pressure is commonly used as an indicator of airway seal adequacy. Similarly, flexible fiberoptic bronchoscope examination is often employed to assess proper placement of airway devices. We hypothesize that airway leak pressures with the ILA-SP will be superior to the LMA upon initial device placement, and ten minutes after device placement. Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached. Ease of placement, fiberoptic grade of laryngeal view, and complications (airway related, gastric insufflation, trauma) will also be assessed.
