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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 1)C-LMA group

Device: Insertion of C-LMA
After induction of general anesthesia, C-LMA or Air-Q was inserted according to randomly allocated group.

Active Comparator: 2)Air-Q group

Device: Insertion of air-Q according
After induction of general anesthesia, C-LMA or Air-Q was inserted according to randomly allocated group.

Outcome Measures

Primary Outcome Measures

  1. 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

  1. 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

  1. Ease of insertion [During and 1 min after insertion of each device]

    Ease of insertion was graded from 1 to 4.
