Design outcomes

Primary

MeasureTime frame
Optic nerve sheath diameter (ONSD) in both the groups at T0, T1, T5 and T10 1. Baseline ONSD value before induction (T0) 2. ONSD value after 1 minute inserting ProSeal LMA/I-Gel (T1) 3. ONSD value after 5 minutes inserting ProSeal LMA/I-Gel (T5) 4. ONSD value after 10 minutes inserting ProSeal LMA/I-Gel (T10)Timepoint: Optic nerve sheath diameter (ONSD) in both the groups at T0, T1, T5 and T10 1. Baseline ONSD value before induction (T0) 2. ONSD value after 1 minute inserting ProSeal LMA/I-Gel (T1) 3. ONSD value after 5 minutes inserting ProSeal LMA/I-Gel (T5) 4. ONSD value after 10 minutes inserting ProSeal LMA/I-Gel (T10)—

Secondary

MeasureTime frame
1. Hemodynamic response (SBP, DBP, MAP & HR) in both the groups at T0, T1, T5 & T10 2. Co-relation of hemodynamic changes with changes in ONSD at T0, T1, T5 & T10Timepoint: T0 is baseline(before induction ) T1-after 1 minute T5-after 5 minutes T10-after 10 minutes—
