A Prospective, Randomized Non- Crossover Investigation of the LMA Unique TM and the Self Pressurized Air-Q TM Intubating Laryngeal Airway in Children

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.
