Table 2. Insertion Success Rates for the Airway Device and Orogastric Tube, Oropharyngeal Leak Pressure, and Fiberoptic Position

* Not attempted in 1 patient because of air leak from drainage tube;

† not attempted in 23 patients because of failure to follow protocol;

‡PLMA  failed to form an effective airway in 3 patients;

§ problem with fiberoptic scope in 2 patients and data not collected;

# investigators failed to collect data in 78 patients.

Data are mean ± SD (range) or numbers (%).

PLMA ™= laryngeal mask airway ProSeal ™;LMA ™= laryngeal mask airway Classic ™; NS = not significant; UES = upper esophageal sphincter.
