Supraglottic Airway Device
Conditions
Keywords
elective surgery, undergoing general anesthesia, elderly adult patients
Brief summary
Supraglottic airway devices (SADs) are well established in anesthetic practice. Among these devices, the i-gel has been typically widely used. The self-pressurised air-Q intubating laryngeal airway (air-Q sp) 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 similar to the original air-Q, except the inflatable cuff. The aim of this randomized trial was to compare the clinical performance of the i-gel and the air-Q sp in elderly patients
Interventions
DEVICEInsertion of the i-gel
After induction of general anesthesia, the i-gel will be inserted according to randomly allocated group.
DEVICEInsertion of the air-Q sp

Inclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| airway leak pressure measured after device insertion | within 5min after 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 parameters (insertion time and ease of insertion) | 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. Ease of insertion was graded from 1 to 4. |
