Design outcomes

Primary

MeasureTime frame
To measure the optic nerve sheath diameter in patients with PEEP compared to patients without PEEP at various time intervalsTimepoint: T1 Baseline before induction of anaesthesia in supine position. T2 2 mins after induction of anaesthesia in supine position T3 2 mins after creation of pneumoperitoneum T4 2 mins after steep head down tilt a)After 30 minutes b)After every one hour T5 2 mins after extubation—

Secondary

MeasureTime frame
