Primary outcomePrimary: Success of Insertion at First Attempt — 50; 60 participants
Summary
The purpose of this study is to compare two insertion techniques of large size ProSeal laryngeal mask airway. We hypothesized that insertion of ProSeal laryngeal mask airway with 90-degree rotation would reduce the contact surface between the device and pharyngeal wall and make it easy to advance the device over the smooth angle against the posterior pharyngeal wall.We compared the success rate and incidence of complication of the standard technique with the rotational technique.
