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.

Inclusion criteria
* Adult patients (20-75 of age) scheduled for elective surgery of short duration (less than 2 hr) undergoing general anesthesia using supraglottic airway
Exclusion criteria
* Patients with a potentially difficult airway, risk of aspiration such as gastroesophageal reflux disease, or active upper respiratory tract infection
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| Ease of insertion | During and 1 min after insertion of each device | Ease of insertion was graded from 1 to 4. |
