Comparison of clinical performance between Ambu Aura Gain™ and I-gel® inserted by trainee anesthesia residents: A prospective randomized control study

Background and Aims: Early training with supraglottic airway devices (SGAD) are imperative for training. This study was done to assess the oropharyngeal leak pressure (OLP) when 1 st year anaesthesia residents inserted Ambu Aura Gain™ and I-gel ® devices. Materials and Methods: A prospective randomized observational study was conducted on 200 1 st year anesthesia residents for SGAD insertion. The trainees were randomly allocated into groups (Group A: Ambu Aura Gain™ and Group I: I-gel ® ). The OLP was compared in each group along the first attempt success rate, total insertion attempt, insertion time, ease of SGAD insertion, ease of gastric tube insertion, fiberoptic view, and complications associated with Inflatable SGAD aura gain and noninflatable SGAD. Results: The mean OLP was 29.31 ± 5.93 and 30.03 ± 4.84 cmH 2 O for I-gel ® and Ambu Aura Gain™, respectively ( P = 0.348). The first attempt success rate was 96% for I-gel ® and 89% for Ambu Aura Gain™ ( P = 0.06). Effective device insertion time was 28.76 ± 7.74 s for I-gel ® and 38.42 ± 8.05 s for Ambu Aura Gain™ ( P < 0.001). In Group A 7%, 49%, 36%, and 8% of patients had 4, 3, 2, and 1 fiberoptic scores, respectively, and 9%, 54%, 32%, and 5% of patients in Group I had scores of 4, 3, 2, and 1, respectively. Conclusion: I-gel ® is better in terms of quicker insertion by anesthesia trainees than the Ambu Aura Gain™.
