Comparison Of the Clinical Performance of Two Second-Generation Supraglottic Airway Devices (I-Gel vs Ambu Auragain) In Adult Patients Undergoing Elective Surgery Under General Anesthesia

Background: Second-generation supraglottic airway devices are increasingly used as alternatives to endotracheal intubation because of their ease of insertion and improved airway sealing characteristics.

Aim: To compare the clinical performance of I-gel and Ambu AuraGain in adult patients undergoing elective surgery under general anaesthesia.

Methods: A prospective randomized observational study was conducted in 60 patients divided into two groups receiving either I-gel or Ambu AuraGain. Quality of insertion, oropharyngeal leak pressure, airway sealing quality score, gastric tube insertion, hemodynamic parameters, and postoperative complications were evaluated.

Results: Demographic characteristics were comparable between groups. Ease of insertion and number of attempts were similar; however, insertion time was significantly shorter with I-gel (15.87±1.36 s) compared to AuraGain (20±2.81 s). Oropharyngeal leak pressure was significantly higher in the AuraGain group (28.33±1.52 cmH₂O vs 22.57±1.01 cmH₂O). Gastric tube insertion required fewer attempts with AuraGain, while hemodynamic parameters and postoperative complications were comparable.

Conclusion: Both devices were effective and safe for airway management; I-gel provided faster insertion whereas Ambu AuraGain offered superior airway sealing and gastric tube insertion performance
