Study Overview
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

- Accepts Healthy Volunteers
- No
Inclusion Criteria
- •1. elderly adult patients (65-90 of age) scheduled for elective surgery undergoing general anesthesia using supraglottic airway
Exclusion Criteria
- •1. Patients with a potentially difficult airway, risk of aspiration such as gastroesophageal reflux disease, or active upper respiratory tract infection
Arms & Interventions
the i-gel group
After induction of general anesthesia, the i-gel will be inserted according to randomly allocated group.
Intervention: Insertion of the i-gel (Device)
the Air-Q sp group
After induction of general anesthesia, the air-Q sp will be inserted according to randomly allocated group.
Intervention: Insertion of the air-Q sp (Device)
Outcomes
Primary Outcomes
airway leak pressure measured after device insertion
Time Frame: 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 Outcomes
- insertion parameters (insertion time and ease of insertion)(During and 1 min after insertion of each device)
