Effect of position on ProSeal™ LMA

Parameter Supine position Lateral position P
VTI (ml) 151.18±59.36 151.18±59.36
VTE (ml) 148.76±58.35 147.44±59.04 0.105
FVL (%) 1.51±2.83 2.76±4.06 0.040
Seal pressure (cm H2O) 17.53±5.04 12.76±3.36 0.000
EtCO2 (mmHg) 37.32±3.37 38.76±3.59 0.001

Data are expressed as mean±standard deviation. The P<0.05 is statistically significant. VTI – Inspired Tidal volume, VTE – Expired Tidal volume, FVL – Fractional volume loss
