Abstract
Supraglottic airway devices have been increasingly used because of their several advantages. Previous studies showed that the small-sized i-gel provides effective ventilation for young pediatric patients; however, few studies have reported the use of AuraGain in these patients. Herein, we compared the clinical performance of AuraGain and i-gel in young pediatric patients aged between 6 months and 6 years old and weighing 5–20 kg, who were scheduled to undergo extremity surgery under general anesthesia. In total, 68 patients were enrolled and randomly allocated into two groups: AuraGain group and i-gel group. The primary outcome was the requirement of additional airway maneuvers. We also analyzed insertion parameters, fiberoptic bronchoscopic view, oropharyngeal leak pressure, and peri-operative adverse effects. Compared with the AuraGain group, the i-gel group required more additional airway maneuvers during the placement of the device and maintenance of ventilation. The fiberoptic view was better in the AuraGain group than in the i-gel group. However, the oropharyngeal leak pressure was higher in the i-gel group. AuraGain might be a better choice over i-gel considering the requirement of additional airway maneuvers. However, when a higher oropharyngeal leak pressure is required, the i-gel is more beneficial than AuraGain.

Supraglottic airway devices form a group of airway devices that are inserted into the pharynx for ventilation
The remaining 68 patients who agreed to participate were allocated into two groups, namely, the AuraGain and i-gel groups
One patient with laryngospasm during device insertion in the i-gel group was excluded from the analysis, since device failure was determined, and an endotracheal tube was inserted (Figure 1)
Summary
Supraglottic airway devices form a group of airway devices that are inserted into the pharynx for ventilation Since their introduction into medical practice, supraglottic airway devices have proven safe and efficient in various settings [1]. They have several advantages over endotracheal tubes. Some previous studies have reported that supraglottic airway devices reduce the incidence of postoperative airway complications [5,6,7,8]. Given these advantages, supraglottic airway devices have been increasingly used worldwide
