The Ambu Auragain is a 2nd generation laryngeal mask airway that is widely used in adult and pedicatric patients. While its use is generally recommended in patients undergoing surgery in the supine position, depending on patient characteristics, type of surgery and experience of the anesthesiologist, it may also be used in the lateral or prone position. There have been reports of LMA use in patients undergoing short procedures in the prone position, but its safety in pediatric patients is not clear. This study was designed to compare oropharyngeal leak pressure between children undergoing surgery in the supine and prone position using the Ambu Auragain LMA.

Oropharyngeal leak pressure immediately after LMA insertion
Oropharyngeal leak pressure is commonly used as a parameter to assess the clinical performance of supraglottic airway devices (SADs). It is defined as the anesthesia circuit pressure at which a gas leak occurs around the SAD.
Time frame: During procedure (Immediately after AmbuAuragain LMA insertion)
Oropharyngeal leak pressure 10 minutes after positioning for surgery
