A Comparison of the I-gel and Self-pressurised Air-Q Intubating Laryngeal Airway (Air-Q sp) in the Elderly Patients

Yonsei University100 enrolled

Overview

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

Medical Language ↔ Plain English

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

Outcomes

Primary Outcomes

airway leak pressure measured after device insertion

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.

Time frame: within 5min after insertion of each device

Secondary Outcomes

insertion parameters (insertion time and ease of insertion)

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.

Time frame: During and 1 min after insertion of each device
