Background: Ambu AuraGain and i-gel have different characteristics in design each other. However, few reports evaluate which device has more benefits for ventilation in children undergoing paralyzed general anesthesia. This prospective, randomized controlled trial compared the clinical performance AuraGain and i-gel in anesthetized children.
Methods: Children aged between 1 month and 7 years undergoing elective surgery were randomly assigned to the AuraGain and i-gel groups. The primary outcome was initial oropharyngeal leak pressure (OLP). Secondary outcomes were OLP at 10 min post-insertion, first-attempt and total insertion success rates, number of attempts and ease of gastric suction catheter placement, peak inspiratory pressure, fiberoptic bronchoscopic view score, ventilation quality, requirement of additional manipulation post-insertion, and complications.
Results: Data of 93 patients were analyzed. The initial OLPs of the AuraGain and i-gel were 27.5 ± 7.7 and 25.0 ± 8.0 cmH2O, respectively (P = 0.130). The OLP was significantly increased 10 min post-insertion in both groups. The initial success rates of the AuraGain and i-gel insertion were comparable. Suction catheter placement via the gastric port was easier (P = 0.018) and fiberoptic bronchoscopic view was better with the AuraGain (P < 0.001). The i-gel required additional manipulations post-insertion (P = 0.038). The incidence of complications during the emergence period was 10.8% for the i-gel and 2.2% for the AuraGain (P = 0.1).
Conclusions: OLP is comparable between AuraGain and i-gel. The AuraGain would be more favorable than the i-gel for use in pediatric patients under general anesthesia considering other outcomes.
