Parameter i-gel® (n=52) PLMA (n=34) P
Seal pressure (cm H2O) in Supine position 21.94±5.82 17.53±5.05 0.001
Seal pressure (cm H2O) in Lateral position 15.54±5.37 12.76±3.37 0.009
Difference in Seal Pressure (cm H2O) from supine to lateral position 6.40±4.87 4.76±4.6 0.004
Percentage change in Seal pressure from supine to lateral position -28.14±18.86 -24.06±19.75 0.339

Data are expressed as mean±standard deviation. The P<0.05 is statistically significant. PLMA – ProSeal laryngeal mask airway
