Oropharyngeal leak pressures between devices.

Parameter Oropharyngeal leak pressure (cm H2O) value

Neutral28 ± 4.1922 ± 3.23<0.001
Flexion32 ± 4.11 25 ± 3.64<0.001
Extension24 ± 4.00 19 ± 2.61<0.001
Lateral rotation28 ± 3.1522 ± 2.74<0.001

Data shown are mean ± SD. < 0.05 is considered significant.
The oropharyngeal leak pressures were significantly higher for ProSeal LMA compared with the I-gel in neutral, flexion, extension, and lateral rotation positions.
