Supraglottic airway devices (SAD) are routinely used for securing the airway. Clinical performance of three SAD in adult patients under general anesthesia was compared.
American Society of Anesthesiologists physical status I-III subjects were randomly assigned to I-gelTM (I), LMA supremeTM (L) or Ambu AuragainTM (A) group with 30 in each group. Time of insertion of SAD was the primary objective. Ease of insertion, number of attempts for insertion, oropharyngeal leak pressure (OLP), airway maneuver requirement, difficulty in placing gastric tube and complications were assessed.
Demographic data did not differ between the groups. Group I (16.9 ± 4.9 s) had significantly shorter time of insertion in comparison to Group L (19.6 ± 5.2 s) and Group A (22.1 ± 5.7 s) (P = 0.001). OLP for group A (29.8 ± 3.0 cmH2O) was higher than Group L (24.1 ± 6.3 cmH2O) and Group I (9.4 ± 6.1 cmH2O) (P < 0.001). No statistical significant difference was observed in terms of number of attempts for insertion (P = 0.232), ease of insertion (P = 0.630) airway maneuver requirement (P = 0.585), difficulty in gastric tube placement (P = 0.364) and complication (P = 0.730) in between the groups.
The study demonstrated that all three devices are convenient and effective to be used for airway management in adults under general anesthesia. However, shorter insertion time required for I-gel can be suitable during resuscitation and emergencies, while Ambu Auragain with maximum OLP can be useful in reducing the risk for aspiration.
