Overview
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.

Eligibility Criteria
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
Outcomes
Primary Outcomes
airway leak pressure measured after device insertion
Time Frame: 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 Outcomes
- Insertion time(During and 1 min after insertion of each device)
