Table 6.
Oropharyngeal leak pressures between devices.
| Parameter | Oropharyngeal leak pressure (cm H2O) | P value | |
|---|---|---|---|
| ProSeal LMA | I-gel | ||
| Neutral | 28 ± 4.19 | 22 ± 3.23 | <0.001 |
| Flexion | 32 ± 4.11 | 25 ± 3.64 | <0.001 |
| Extension | 24 ± 4.00 | 19 ± 2.61 | <0.001 |
| Lateral rotation | 28 ± 3.15 | 22 ± 2.74 | <0.001 |
Data shown are mean ± SD. P < 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.
