The Clinical Efficacy of Supraglottic Airway Device, Self-pressurized Air-Q Intubating Laryngeal Airway (ILA -SP) in Adult Patients: Comparison With Classic-laryngeal Airway (c-LMA)
Study Details
Study Description
Brief Summary
Supraglottic airway devices (SADs) are well established in anesthetic practice. Among these devices ,classic laryngeal airway has been typically widely used. The self-pressurised air-Q (air-Q) is newly developed supraglottic airway devices. It is a new single-use device that may optimise the airway sealing while reducing the potential for postoperative complications such as sore throat. The overall structure of the air-Q SP is identical to the original air-Q, except with regard to the inflatable cuff. The aim of this randomized trial was to compare the clinical performance of the classic LMA and the air-Q SP.

Outcome Measures
Primary Outcome Measures
- airway leak pressure measured after device insertion [within 5min to 10 min insertion of each device]
Airway leak pressure was determined by adjusting the expiratory valve of the breathing circle to 40 cmH2O (fixed fresh gas flow 3 L/min) and recording the pressure when equilibrium was reached.
Secondary Outcome Measures
- Insertion time [During and 1 min after insertion of each device]
Insertion time was defined as the time from the attending anesthesiologist picking up the LMA until the confirmation on capnography.
Other Outcome Measures
- Ease of insertion [During and 1 min after insertion of each device]
Ease of insertion was graded from 1 to 4.
