Comparison of the Clinical Performance and Safety of the Ambu®AuraGainTM Laryngeal Mask in Children Undergoing Surgery in the Supine and Prone Position - A Prospective, Noninferiority Clinical Trial
Comparison of the Clinical Performance and Safety of the Ambu®AuraGainTM Laryngeal Mask in Children Undergoing Surgery in the Supine and Prone Position - A Prospective, Noninferiority Clinical Trial
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.
Inclusion Criteria:
Pediatric patients undergoing surgery within 2 hours under general anesthesia in either the supine or prone position using the Ambu Auragain LMA.
Patients aged 2-12 years, weight 10-30 kg, ASA class 1~3
Exclusion Criteria:
Active URI, symptomatic lung disease (uncontrolled asthma, pneumonia etc), patients with history of difficult airway, anticipated difficult mask ventilation, risk of aspiration such as gastroesophageal reflux
